I Have a Research Support System

On Tuesday, at 8 o'clock in the morning, everyone in the research team came to Caiyi ahead of schedule and began to arrange the conference room on the third floor.

Sun Wo went to the fruit shop on a street in the North District to pick up the fresh fruit platter ordered yesterday;

Wu Feifei took a bag of tea leaves from Wei Xingsi, then boiled water to make the tea, and prepared disposable paper cups and plastic cup holders.

Duan Yun was responsible for carrying the whole box of mineral water, and placed a bottle in front of each teacher's seat;

Chen Wanqing, Han Jiaying and the others placed a triangular standing sign with their names in front of each teacher's seat, and distributed a meeting material.

Considering that there are enough people, Xu Qiu did not choose to help, but stayed in the 216 office downstairs, making the last preparations before the conference speech.

At the beginning, he prepared according to the English report by referring to the situation of attending the meeting at Gong Yuanjiang's side last time.

As a result, I found out later that today's meeting was reported in Chinese, because Bazan was present last time, but no foreigners participated this time.

This relieved Xu Qiu a lot of pressure.

In fact, this kind of conference, whether it is in Chinese or English, has little influence on professors and scholars.

They basically have a bilingual foundation for scientific research. After all, SCI papers account for the largest proportion of evaluation indicators. If English is not good, it is difficult to be evaluated as a professor if they cannot publish articles.

It is the students who are most affected.

Language application, including listening, speaking, reading and writing.

For the students of Shanghai Comprehensive University, they may be good at reading and writing. After all, if they can pass the exam, they will probably not be too bad in this aspect; but it is not necessarily the case in listening and speaking, and the differences between different students will be very different. big.

For non-English majors, it is estimated that only about half of them can communicate with Wai Guoren in English when they graduate from senior year.

That is to say, if foreign professors come to Shanghai Comprehensive University to give academic reports, half of the students will not be able to understand them.

Moreover, some students could not even pass the fourth grade.

Of course, this is mainly because the Shanghai Comprehensive University does not require CET-4 or CET-6 for undergraduate graduation, as long as you pass the comprehensive English test in the school.

The comprehensive English test in the school adopts the grade point system. Although the difficulty of this test is level 8, it is difficult to get an A, but as long as you do not miss the test, it is relatively easy to get a C or D, and you can graduate normally.

The only problem is that the grade point will be pulled down ugly. Taking a four-credit D is equivalent to failing a three-credit course.

At 8:50 in the morning, the layout of the venue was completed, and many teachers and students had rushed over one after another.

Wei Xingsi, in a neat suit, stood at the door of the conference room with a smile on his face, like a salesman, welcoming the visiting teachers.

The visiting teachers are mainly off-campus scholars in the field of organic photovoltaics.

Because there are rarely multiple research groups with overlapping research directions in a school, there are relatively few teachers in the school. Xu Qiu only saw Tang Yunkun.

In the venue, Tang Yunkun and Feng Shengdong were sitting together. After a dinner on Sunday, they were connected.

The two happened to be alumni, both of whom graduated from the Department of Physics of Shanghai Comprehensive University, but they were not at the same level. Tang Yunkun graduated three years earlier than Feng Shengdong, so there was no intersection before.

Although the paths chosen by the two are different now, one is to teach in China and the other is to develop abroad, but the research fields are related and there are still many opportunities for cooperation.

In addition, a meeting of this level had to be reported to the department, and the department also helped to carry out a wave of publicity warm-up.

Xu Qiu received a notice forwarded by the counselor Bao Wei in the class group, saying that as long as he participated in this conference, he could count as participating in eight academic reports.

This is still very attractive, because you only need to listen to 20 academic reports during the postgraduate period, and now this one is worth eight, which is very cost-effective.

Therefore, the number of people who came to the venue today was a little too high. There were more than 40 chairs in the meeting room, which were not enough, and the seats were filled up quickly.

Seeing this, Wu Feifei sent Sun Wo, Duan Yun and others to the meeting room next door to bring chairs.

But even so, the chairs just moved were not enough.

Therefore, those who came late could only stand and listen to the report.

Xu Qiu sat on the big conference table in the center, next to Wei Xingsi. There was also a special triangular stand in front of his seat, with his name written on it, and he was considered to be enjoying the treatment of a teacher.

Among the visiting crowd, Xu Qiu saw many familiar figures.

Including Mu Xue, the monitor of the Ph.D. class, holding an experiment record book in her hand with a sign-in sheet on it, which is probably used to count the students who come to listen to the report.

In addition, former roommate Tao Yan also came over. His research group office is next door to 216, just upstairs.

Because it was relatively close, he almost got stuck, and when he entered, he found that the venue was full.

Tao Yan retracted his neck exaggeratedly, and he was still muttering something. From the shape of his mouth, Xu Qiu probably said Fuck.

In addition to Tao Yan, there were several other undergraduate graduate students who also came to the venue. Most of them were students in the research group who were in the first or second courses.

And roommate Sun Yifan, who is now in Zhangjiang, did not come over.

After all the teachers attending the meeting arrived, Wei Xingsi went back from the door and sat down at the conference table, and whispered to Xu Qiu, If I knew there were so many people, I would have applied for a large lecture theater.

Xu Qiu also responded in a low voice: The main reason is that our counselor sent a notice, and many students came to listen to the lectures. Because graduate students need to listen to a certain number of academic reports before they can graduate.

Wei Xingsi was stunned: So that's the case. I said why there are so many students I don't know.

Xu Qiu said casually: It is estimated that there will be fewer people after a while. Many people should come to sign in and then leave.

Wei Xingsi laughed: That's right, it's still a bit difficult for people from other fields to listen to our professional reports.

After chatting for a while, Wei Xingsi looked down at his watch and found that it was almost nine o'clock, so he got up and walked to the podium to preside over the meeting.

After adjusting the microphone, Wei Xingsi said calmly and frustratingly: I announce...the organic photovoltaic seminar has officially started...First of all, let me introduce the participating guests, namely Gong Yuanjiang from Kainan University...

When Wei Xingsi said this, he paused for a moment, Gong Yuanjiang got up tacitly, and waved to everyone. The others immediately understood and began to applaud.

After that, every time Wei Xingsi pronounced a name, the corresponding teacher stood up to say hello, and then the others applauded.

Although there was no rehearsal in advance, these professors all had rich experience in participating in meetings. Gong Yuanjiang took the lead, and everyone else understood.

Lu Changjun from the Chinese Academy of Sciences...

Bao Yuanyou from Jinghang University...

Zheng Xiao from Sichuan University...

Feng Shengdong from Lund University in Sweden...

Ma Weiwei from Ancheng Jiaotong University...

Liang Haoxian from Southern University of Technology...

Finally, the work of our research group will be reported by my student Xu Qiu...

When it was Xu Qiu's turn, the cracking sound from the audience was the most intense.

After all, many of the people present are Xu Qiu's classmates, and reporting at the conference as students will attract more people's attention.

Tao Yan also yelled Okay!, originally he saw such a crowd of people and planned to run away as soon as he signed, but now he heard Xu Qiu's name and decided to stay and listen. listen.

After graduating from the undergraduate course, although the two had contacted from time to time, and the research group office was very close, they were not as close as before.

Tao Yan also wants to see how far Xu Qiu has achieved scientific research.

After introducing the guests, Wei Xingsi continued to host the meeting:

First of all, we have invited Professor Gong Yuanjiang from Kainan University to report.

Gong Yuanjiang's main research direction is organic small molecule donor materials. His team has published more than 20 articles in top academic journals such as AM, JACS, and EES, with an H factor of 35. He was selected as a Changjiang scholar in 2013...

The topic of Gong Yuanjiang's report is the progress of all small molecule non-fullerene organic solar cells. Welcome!

Accompanied by applause, Gong Yuanjiang took the stage, took over Wei Xingsi's position, and began to report:

Good morning, everyone. It is a great honor to be the first to report at the conference. Today I will mainly share with you some of the work of our research group in the past year...

Xu Qiu was listening to Gong Yuanjiang's report while staring at his computer.

It was his turn to report soon, Xu Qiu was a little bit nervous, the main reason was that there was an unexpected unexpected situation, he had to face not only the teachers attending the meeting, but also his classmates them.

However, tension is tension, and the work that should be done cannot be left behind.

During Gong Yuanjiang's report, Xu Qiu simultaneously used the computer to record what the other party said.

Gong Yuanjiang heard that he is a veteran who often gives academic reports, and he has a very good command of the rhythm of the language. He was chosen to be the first to appear on the stage before, also to make a good start.

Now they are regarded as a successful transformation, and they have taken the ride of the ITIC series of non-fullerenes, and achieved remarkable results.

Gong Yuanjiang reported a total of five works, two AM, one AEM, one JMCA and one ACSAMI, which is a series of work based on the modification of small molecule donor materials.

The modification method is somewhat similar to Xu Qiu's optimization of the ITIC series of acceptor materials.

At the beginning, a material was developed as a benchmark, and then the molecular structure was continuously fine-tuned through the feedback obtained during device preparation and experimental characterization.

Every time it is adjusted, an article is published.

If the performance improvement is relatively large, it is a large article, and if the performance improvement is relatively small, it is a small article.

This is also the essence of applied research. To put it bluntly, it is constant trial and error.

Excluding cheating factors, the difference between big guys and ordinary researchers is that big guys have a higher success rate when they try and make mistakes.

Therefore, they will get more resources, so that the expectation of the final result is the highest.

Half an hour passed quickly, and Gong Yuanjiang successfully completed the first report. After answering a few questions from the audience, Wei Xingsi seamlessly joined the stage and continued to host the meeting:

Next, please ask Xu Qiu to report for everyone.

Xu Qiu is a direct Ph.D. student in our research group, a first-year student, and is currently the leader of the organic photovoltaic team in the group. His main research direction is non-fullerene acceptors. He has published in Nature Energy, Joule, NC, AM Published more than 10 academic papers as the first author in other journals...

The topic of Xu Qiu's report is the progress of non-fullerene organic solar cells. Welcome!

Xu Qiu deliberately wore a formal suit today, and adjusted his collar before going on stage.

Then, he glanced at the members of the research team at the side and rear, and the junior girl responded with a full smile, and Duan Yun gave him a thumbs up...

When he and Wei Xingsi crossed each other, Teacher Wei also gave him an encouraging look.

He looked into the distance again, Tao Yan and other students also nodded at him, most of them did not leave.

Seeing so many people supporting him, Xu Qiu suddenly became less nervous.

Good morning, teachers and students...

Initially, we designed a molecule called IDT-ICIN...

Afterwards, we upgraded IDT to IDTT, expanded the conjugate length of the central D unit, and developed a material called ITIC...

Now, based on ITIC's latest derivative IDIC-4F, which is just accepted by Nature Energy, the device efficiency reaches 13.5%...

Finally, we summarize the recent work in the Joule review, and at the same time look forward to the future of the field of organic photovoltaics...

Xu Qiu reported in the order previously scheduled, and the time control was very good, ending in twenty-nine minutes.

When one article after another was displayed like a revolving lantern, the teachers and students in the audience discussed in low voices.

Xu Qiu's classmates, although they had heard that Xu Qiu had won the national award as the first doctoral student, they didn't know the process and details of the award, only the final result.

Now after hearing this report, they all immediately understood why Xu Qiu's ability surpassed the orthodox second and third year seniors and won the first place.

Just looking at the number of achievements, it is estimated that it is several times that of the second place.

As for the teachers present, especially the teachers who didn't have much contact with Wei Xingsi, although they knew that Wei Xingsi's group had published a lot of articles, they were still taken aback when they saw the number of these articles.

In just one year, a team of less than ten people has produced nearly thirty high-quality articles, which is simply a high-yielding competition sow.

And, crucially, these articles were all about the man on stage.

Xu Qiu is either the first author of the article or the second author of the article.

People who belong to the same academic circle, they are very clear about the meaning of the ranking of the authors of the articles.

For most research groups, if 30 articles are published, from 5 students in the group, then the average distribution is roughly 10 articles per person, one or two articles, which is relatively scattered.

And if a student puts all 30 articles in the group on the first or second work, it means that the student is the main participant in all the work in the group.

This is a very exaggerated phenomenon, indicating that the actual contribution of this student has most likely exceeded that of the tutor of the research group.

The teachers present immediately understood why Wei Xingsi pushed Xu Qiu hard.

If the title of the article was based entirely on his contribution, Xu Qiu's achievements are already higher than Wei Xingsi's.

After Xu Qiu's speech was over, the audience burst into warm applause, one after another, which lasted for about half a minute before stopping.

Xu Qiu was also very satisfied with his report. He was in a very relaxed state at this time, and complained in his heart: This is because I only talked for 29 and a half minutes, so do I need to use applause to force it into 30 minutes?

After the applause stopped, Wei Xingsi stood up and said, Do you have any questions about Xu Qiu's report?

As soon as the words were spoken, several people raised their hands. Wei Xingsi looked around and finally chose one at random.

The selected lucky guy Xu Qiu didn't know him. He was male, about 30 years old, and had no distinctive appearance. He might be a green pepper scholar, or he might be a postdoctoral fellow sent by the research group to attend the conference.

The strange green pepper scholar first commented: The published articles are very powerful, and the work is also very systematic.

Then he asked: Did this Nature Energy article just be accepted? I didn't find it on the Internet just now.

As soon as Xu Qiu heard this question, he knew that the other party was probably not familiar with Wei Xingsi, otherwise he would most likely receive a printed copy of the Nature·Energy article from Teacher Wei.

However, Xu Qiu still responded seriously: Yes, I just received news from the editor last Friday, and it is estimated that the electronic version of the article will be online in a month.

The strange green pepper scholar asked: Is it convenient to send me a copy of the literature? There is also a review article on Joule, can you also give me a copy?

No problem, I'll give you a copy after the meeting. These are trivial matters, Xu Qiu immediately nodded in response.

Not every school will buy all the journal resources. For example, Shanghai University of Technology did not buy the electronic version of the Nature series of journals, probably because it is too expensive.

Usually Xu Qiu and the others want to download articles in the Nature series. They either turn to the library for help, use the academic resources of universities and research institutes across the country to find documents, or send emails to find the authors themselves.

Just like the Natural Energy article that Xu Qiugang received, if he wants to read his own articles in the future, he will have to pay to read them.

It’s a bit similar to an online article. If the author wants to read his own work, or publish this chapter in the paid chapter, he must subscribe first before posting. It’s... normal, because the copyright does not belong to the author.

Thank you, the unfamiliar green pepper scholar thanked, and finally got to the point: Xu Qiu, I saw that you listed a lot of content in the prospect section, can you talk about the stability of the device specifically?

Of course. Xu Qiu speculated that this green pepper was probably doing stability-related research, so he responded by adding examples and ideas: There are still many methods, and polymer receptors can be introduced as the third group. points, such as adding a small amount of N2200 to the binary system..., can design receptor molecules with non-conjugated central units..., and also...

Xu Qiu didn't hide his secrets. He analyzed all the common methods to improve device stability, and at the same time, he also shared his recent inspiration from Xu Zhenghong's NC work.

The polite green pepper scholar digested for a while, nodded and said, Thank you, I have no problem.

Later, Wei Xingsi called another student who raised his hand to ask a question.

Xu Qiu still had a slight impression of the student who was called up. He had met each other when he attended Gong Yuanjiang's meeting last time. He was a student of Jinghang University Bao Yuanyou.

As for the specific name, he couldn't remember.

Bao Yuanyou's student did not comment on Xu Qiu's work, but asked directly: I saw that Xu Qiu's report mentioned the scrape-coating experiment... I am doing scrape-coated devices recently, but the success rate is not high , would you like to tell me how your scraping experiment was carried out? And are there any problems that need to be paid attention to in operation?

Xu Qiu operated the laser pointer and transferred the page displayed on the PPT to the scratch-and-paint AM article just published.

Although the scratching experiment is mainly in charge of the seniors and juniors, Xu Qiu also often plays with these instruments in the simulation laboratory, so he is no stranger to this. He thought for a moment and responded:

For scraping, the experimental operation itself is not difficult, but the requirements for the instrument are relatively high. If there are problems such as uneven blades and low precision in height control, it is easy to cause the thickness of the obtained film to be very uneven, and it is easy to appear. The phenomenon of short circuit or open circuit, now there are manufacturers specializing in the production of scraping machines...

Not all systems are suitable for scraping coating. It is better to choose a system with high charge mobility and insensitive to battery size and thickness to perform scraping operation. The performance of the scraping coating device obtained by such a system will not be better than that of traditional Spin-coated devices are too poor...

In addition to scraping the effective layer, it is also possible to scrape the electrodes and transport layer materials, such as PFN, PEIE and other solution processable transport layer materials, and silver nanowires and other solution processable electrodes. Scratch...

Okay, okay... Bao Yuanyou's student nodded again and again, and asked again: Then is there any scraping machine that you recommend?

Xu Qiu was about to mention Blue River's company, planning to help promote it, but saw Wei Xingsi winking at him.

After thinking about it carefully, at the academic exchange meeting, it seemed that it was not very good to discuss business, so he changed his words:

As for the instrument, we can talk about it in detail after the meeting, or you can also read the AM article published by our research group, and the model of the instrument used is also marked in the supporting information.

Okay, thank you. Bao Yuanyou's students finished asking questions, and Wei Xingsi chose the third questioner again, which was Mu Xue, monitor of Xu Qiu's doctoral class.

It was not surprising that Mu Xue was selected, because there were few girls present, and she was the only female student who raised her hand.

Xu Qiu, I would like to ask you a question on behalf of my classmates. How can I publish ten articles a year like you? Mu Xue asked.

Uh... this is really a 'good' question... Xu Qiu thought for a moment, and decided to shake his head: I won't talk about hard work, talent, opportunity, etc., which are commonplace, but I can provide you with a Feasible suggestions, so that you can also publish ten articles a year...

What suggestion? Mu Xue suddenly became interested, and the other teachers and students present were also attracted by Xu Qiu's words.

Xu Qiu said solemnly: Why don't you change your supervisor, come to our research group, and join the embrace of organic photovoltaics...

As soon as this remark came out, the teachers and students present were amused, and Wei Xingsi added additionally: Mu Xue, if you are willing to come to our research group, I will talk to Mu Zhengchuan and ask him for someone.

Mu Xue blushed, hurriedly waved her hands and said, No, no need.

After dealing with Mu Xue, the time for asking questions has passed for more than ten minutes.

But there were still a lot of people raising their hands in the audience. Wei Xingsi saw that Liang Haoxian had also raised his hand, so he asked him to ask the last question.

Generally, in this kind of meeting, students ask a lot of questions, and the teachers are relatively cold, unless they come out to ask questions when they encounter something of great interest.

I won't comment on the work in detail. Everyone can see this achievement. Liang Haoxian changed the subject and asked directly: Xu Qiu, where do you think the upper limit of the organic photovoltaic field will be in the next year or two? Device efficiency How much can you do?

Liang Haoxian's question is also a question that the scholars present are more concerned about.

Except for Gong Yuanjiang who had learned some inside information, no one else was aware of Wei Xingsi's research group, or the latest progress of Xu Qiu's current research.

But it's not easy to ask questions directly, asking them to make their latest achievements public.

Therefore, asking questions in this roundabout way is a better choice.

In addition, after learning that Xu Qiu is the hidden boss hidden in Wei Xingsi's research group, they also value Xu Qiu's forward-looking views very much.

In the academic circle, except for the top existence of academicians, there is almost no age discrimination at other times. As long as you are NB enough, you can get the respect of others.

Moreover, the scientific research ability of researchers does not improve steadily with age. The general trend is almost a rapid increase first, then a slow increase, and finally a slow decline.

Many people, the age of key scientific research achievements, are all within 40 years old.

Including many Nobel Prize winners, if they solve a Nobel Prize-level problem in their 30s, there may be no other outstanding achievements after that.

‘Now the first-generation results in the simulation laboratory have reached more than 14%, and there is not much room for improvement. Xu Qiu hesitated for a moment, and decided to keep a low profile, not to say too much: It is expected to break through 15% soon. In the future, I think 16% and 17% also have a chance. As for the threshold of 18%, it is not yet available. can not see.

His personality is different from Wei Xingsi's, he doesn't like to boast about Haikou that hasn't been realized, especially in front of a large crowd, bragging is cool for a while, and it will be embarrassing if Yuan doesn't come later.

Maybe it's because he is still relatively young. Although Xu Qiu has matured a lot with the emergence of the system and various scientific research experiences, he is still a boy in his early twenties in essence.

It is estimated that after a few more years, after graduating with a Ph.D., the last greenness will fade away, and the skin will be thicker.

Liang Haoxian nodded thoughtfully, indicating that he has no other questions.

At the end of the questioning session, Xu Qiu returned to his seat under the applause of everyone, feeling a little emotional in his heart: The questions raised by other people at the meeting can be described as strange and strange, and there are all kinds of them.

But if you think about it carefully, today's meeting is actually just a part of the whole meeting.

When attending a meeting, most of the things are actually done outside the venue.

For example, the efficiency of one-on-one academic exchanges in private is obviously higher for individuals, and it is also possible to chat about things that are inconvenient to chat in public.

Most people don't report on unpublished work in public. They usually report on published articles. For colleagues, these articles have already been seen, so they don't have much meaning.

Only a pioneer like Xu Qiu who is far ahead of others will choose to talk more about his own ideas and provide others with some research ideas.

Wei Xingsi continued to chair the meeting.

The third player in the morning was Ma Weiwei.

After she appeared on the stage, she heard sparse applause, and saw that the audience below had left for about a third of the time after Xu Qiu's speech, and their expressions remained unchanged.

Ma Weiwei didn't have much work, and only published two articles after returning to China.

However, these two articles were spoken by her for half an hour abruptly.

The main reason is to gain a sense of presence. Of the eight guests attending the meeting, she was the one with the least achievements. It may be because of Wei Xingsi's relationship that she was able to attend the meeting.

The academic circle, because of the special system of peer review, is not very objective.

Therefore, it is more important to have more presence. If others know you and have a good impression, they may be more relaxed when reviewing manuscripts.

Of course, those who can be relaxed are generally small articles from the second district, and they will almost be given.

If it is a top journal such as AM and JACS, it will basically be critical.

Because if you want to post articles of this level, everyone is participating in an approximate zero-sum game. If you post more, I will post less.

The fourth in the morning is Feng Shengdong.

He brought some theories and case studies of TAS, TRPL, and THz.

Among them, most of the work is in cooperation with Wei Xingsi, and of course there are some works where he is the first author and Tnu is the corresponding author, which is basically purely theoretical research.

Feng Shengdong came here mainly for cooperation, and he gained a lot.

In the questioning session at the end of the report, several teachers immediately expressed their interest in this research and they wanted to keep in touch with each other.

At noon, everyone went to the cafeteria for a meal, rested for a while, and returned to the venue to continue the meeting.

The first game in the afternoon was Liang Haoxian from Xu Zhenghong's group.

He will talk about the synthesis of ITIC series derivatives and the synthesis of matching donor materials.

From the perspective of research direction, there is a great overlap with Wei Xingsi group.

Therefore, on Monday, Liang Haoxian went to communicate with Wei Xingsi, mainly talking about their general thinking, so as to prevent collision with Wei Xingsi's work.

This is also a purpose of the conference communication, to avoid duplication of effort and waste of resources.

The second session in the afternoon was Bao Yuanyou from Jinghang University.

Not to mention his work, what impressed Xu Qiu the most was his speech ability.

Last time at Gong Yuanjiang's side, Bao Yuanyou reported in English, but he was stuttering.

As a result, Bao Yuanyou also did not speak well in Chinese at this conference, and he was still stuttering.

Xu Qiu guessed that Bao Yuanyou might have obstacles in his own language function.

Probably, this can be regarded as a certain degree of physical disability.

God closed a door for him, and opened a window for scientific research?

The third is Lu Changjun from the Chinese Academy of Sciences.

Lu Changjun mainly reported the research progress of transport layer materials, such as the well-known organic transport layer material PFN that can be processed by solution method, which he and Zang Chaojun of Qingbei University jointly researched.

Now based on continuous optimization of PFN, a series of transport layer materials have been formed, including PFN-Br, PFN-Na, and another system about PDIN, including PDINO, PDIN-Br, etc...

However, regarding the synthesis of donor and acceptor materials, Lu Changjun has not published any major articles for a long time, and he may also be in a low period.

The output of articles by professors in universities and research institutes is also cyclical.

The reason is also very simple. Professors generally do not conduct experiments in person, and students do the work. If the students are good, then there will be more articles. If the students are hip, then the articles will naturally be less.

The powerful or hip stretching here is result-oriented.

If it is deduced forward, for each student, talent, effort, and luck are all considerations that affect the results.

As much as one might hate to admit it, luck is at the heart of it all.

In an industry like scientific research that depends on the sky, no matter how talented you are, no matter how hard you work, no one will be able to stand it if God jokes with you.

Xu Qiu's acquisition of the system is probably a manifestation of his luck.

The last one was Zheng Xiao from Sichuan University.

Their research group did not choose to follow the trend to develop ITIC acceptor materials, but continued to develop the PDI system. This year, they designed and synthesized many kinds of PDI molecules.

Now the holder of the world record of the PDI system has been changed to Zheng Xiao's research group. Their achievements have broken through the device efficiency to more than 10%, using a new type of 3D-PDI molecule.

To some extent, it also inherited Xu Qiu's previous mantle, including the concepts of condensed rings they used, all referring to the AM article on 3D-PDI published by Xu Qiu at that time.

In addition, although Zheng Xiao did not develop ITIC materials by himself, he also used ITIC materials to make a ternary system blended with PDI and published an article on AEM.

It is somewhat similar to the ACSEL article by Mo Wenlin, but Zheng Xiao and the others published it later.

Finally, after five o'clock in the evening, Wei Xingsi announced: The meeting is successfully concluded.

PS: It is recommended on the Internet, let's have a small explosion.
