I Have a Research Support System

In the evening, everyone in the research team went out to have dinner, and the place was chosen at a shop called Gua Lai Da.

The signature of this store is the charcoal-fired copper pot bullfrog. A group of more than a dozen people in the research team sat down at two tables and ordered a total of four double-layer copper pot bullfrogs.

During the meal, Xu Qiu asked Tian Qing who was sitting at the same table: We will go to the beautiful country for a meeting in April, and now we need to prepare the luggage to carry. Do you have any suggestions, Senior Sister Tian Qing?

Tian Qing stopped picking up vegetables, thought for a while, and responded: First of all, I suggest you bring more domestic fast food products, because you may not be used to the food in the beautiful country.

However, it's best to check the customs regulations of the beautiful country online, because not everything can be brought over. I remember that most meat products except fish are not allowed. Tian Qing paused and continued. said:

Of course, this is only so strict when you go through customs. If you just board the plane, most of the food can be carried, but the premise is that you have to finish eating on the plane, or leave the food on the plane when you leave the plane. For example, I brought two boxes of Zhou Huiya with me when I went to the beautiful country, and I finished eating them on the plane...

Sister Tian Qing, can we talk about the key points, do you have any specific recommendations? Xu Qiu asked.

Specific recommendations... Tian Qing said without hesitation: Instant noodles, the three of you can bring ten or fifteen packets of instant noodles, which can cover three or five meals, and eight-treasure porridge is also a good choice.

Instant noodles... eight-treasure porridge? Xu Qiu asked in a bit of astonishment, These things don't sell in the supermarket in the beautiful country?

Tian Qing said Yes, nodded and said: The supermarkets in the beautiful country rarely sell instant noodles and eight-treasure porridge, because their citizens don't like these things very much.

Although there are Chinese supermarkets over there, or the Asian commodity section of some large supermarkets, and Chinese settlements like Chinatown, they will sell these things, but it is hard to say whether they will be sold near the MRS venue where you are.

If there is no sale near the venue, it will be more troublesome. You have to go to other business districts. Because the public transportation in Beautiful Country is not developed, so if you want to go to other business districts, you will probably have to take a taxi, and the cost of taking a taxi will be very high. It costs tens of dollars at every turn, so it’s better to bring it from China by yourself, saving worry and effort.”

Speaking of travel experiences, Tian Qingyue became more and more excited, and added: By the way, when buying food, you should pay attention to meat products such as sausages that are not allowed to enter the country. There is a high probability that marinated eggs are not allowed, and there are instant noodles. It is best not to choose Tang Shuaibo Braised Beef Noodles, you can choose Xin La Noodles and the like...

Xu Qiu complained: I don't buy Tang Shuaibo's braised beef noodles because I'm afraid there is beef in it...

Yes, Tian Qing nodded: If it is found that there are any meat ingredients in the food, it will be fined and confiscated. The same is true for sausages. Although most of the domestic ham sausages are starch, there will always be You can’t bring some meat.”

At this time, Wu Feifei interjected: If we are afraid that we will not get used to eating, we can also eat fast food such as Kaifeng dishes.

Yes, yes, but... Tian Qing paused, and then changed the topic: There are not many Kaifeng dishes in the beautiful country, and the taste is so-so. I ate there last time, and the deep-fried ones were not good. It’s also very oily and salty. Of course, even if there are no Kaifeng dishes around the MRS venue, there are likely to be many other similar fried chicken and burger restaurants around, but eating fried chicken and burgers every day will definitely not get used to it.”

That's true, Wu Feifei thought deeply, and then asked, Apart from food, is there anything else that needs to be prepared?

Tian Qing thought for a moment, and said: If you go to the beautiful country, you will take a long flight, you'd better bring a U-shaped pillow, and a pair of slippers, because sitting for a long time will cause the feet to swell, so you can use it on the plane. Take off your shoes, it will be more comfortable, of course, as long as it doesn't disturb other passengers.

Other aspects... Tian Qing continued: You have already bought the voltage conversion plug before; for the Internet, Mr. Wei has rented WIFI for you; the rest is to bring a change of clothes and a laptop. , mobile phones, credit cards, passports, banknotes and other necessary supplies.”

In the end, Tian Qing smiled: Don't imagine how difficult it is to go abroad. It's quite easy if you have an advantage in English language. As long as you don't go out at night or go to slums, it's actually similar to being in China. It's not as dangerous as it says on the Internet, bullets are flying above my head every day...

‘Is it easy to go abroad? ’ Xu Qiu complained in his heart: If I hadn't personally applied for a visa before, I would have believed in your evil.

...

Time passed quickly, and in the blink of an eye, it was March 31st, the day before Xu Qiu and the others went to the beautiful country to attend the meeting.

This morning, Wei Xingsi organized a simple group meeting in the conference room on the fourth floor of Jiangwan Xiancai.

In the perovskite team, Wu Feifei led Sun Wo, Yu Ya, and Deng Hu to make several batches of devices.

As a result, based on the two-dimensional lead-tin mixed perovskite system, the efficiency was barely increased from the previous 6.6% to 7.0%.

There is very little room for further improvement.

Therefore, Wu Feifei directly chose to organize the article.

With complete experimental data for this kind of small article, Wu Feifei only spent one week writing, revising, and successfully submitting the article to the target journal ACSAMI.

As for future research directions, Wu Feifei listed several new lead-tin mixed systems.

But to be honest, Wu Feifei didn't think the directions she mentioned were better directions. She just proposed the directions first and let Sun Wo do it.

The main reason is that Wu Feifei's recent scientific research ideas are somewhat lacking. This time, she went to the beautiful country to take advantage of the opportunity of the MRS meeting to see if she could find ideas from other people's reports and posters and find a high-quality research direction.

In the current photovoltaic field, the popularity of perovskite photovoltaics is still very high.

Attending the MRS conference this time, there are many bigwigs from the field of perovskite, many of whom are well-known domestic and international scholars who have published articles on CNS. If they leak something in their hands, it is enough for others to drink Mouth soup.

Compared with the perovskite field, there are not many people in the domestic organic photovoltaic field who participated in the MRS conference every year, mainly because the organic photovoltaic field is not a very popular field, so there are not many big names who give reports at the conference .

And if there is no big boss to make a report, it will be difficult to attract ordinary researchers.

Because the meeting, on the one hand, is to listen to the report of the boss and find the future research direction, on the other hand, it is also to make contacts and establish a cooperative relationship between researchers.

Without big bosses, the willingness of ordinary researchers to participate in the conference will be greatly reduced.

Moreover, domestic researchers also need to spend a certain amount of money to go abroad to participate in conferences. Including round-trip air tickets, hotels, meals, and conference registration fees, participating in an international conference costs about 20,000 to 30,000 yuan.

Although most of this cost can be reimbursed, if two international conferences are held every year, 50,000 soft sister coins will be spent a year. It is impossible for most weak chicken research groups to have so much travel expenses that can be reimbursed.

For a general project of 800,000 yuan in four years, the travel expenses are only about 10%, which is about 100,000 yuan in four years.

As for the general project, even a professor can't say with confidence that he can apply for it.

Therefore, there are also thresholds for participating in international conferences.

Unless the tutor is not short of money and can participate at his own expense, otherwise, for the research group with no projects in hand, the students in the group are basically insulated from going abroad to participate in the conference.

Although the number of scholars in the field of organic photovoltaics was bleak in previous years, the situation this year should be different.

Because Xu Qiu's team has repeatedly made breakthroughs in the field of organic photovoltaics, the popularity of the field of organic photovoltaics has soared rapidly.

Now that Xu Qiu is going to give a lecture at the MRS conference, there is a high probability that there will be many more researchers participating in the organic photovoltaic field this year than in previous years.

At least as far as Xu Qiu learned, Gong Yuanjiang, Feng Shengdong, and Ronald would all be there.

Chen Wanqing and Duan Yun have already written their graduation thesis and uploaded the blind-reviewed version of the thesis. Wei Xingsi did not hold them back and let them pass the review.

The next step is to check the plagiarism and submit for review by the department. Because it is all blind review, it is relatively easy. There is no need to manually find review experts, and the department will arrange it directly.

Based on Xu Qiu's stacking system and the results obtained by Ronald's team, Tian Qing began to sort out the Nature Optoelectronics article on the correlation between the device structure, interfacial charge recombination and device performance of stacked devices. Progress... 10%.

Tian Qing was still paddling as usual, she belonged to one of the special groups who didn't work hard but made a lot of scientific research achievements.

To be honest, this relaxed state is quite enviable, but reality does not allow people to stop working hard.

This is related to historical reasons and also to the current situation. The former is due to the tradition of florists, and the latter is the price that latecomers have to pay to catch up with the pioneers.

Xu Qiu rested for a few days after the Nature article was submitted.

Of course, he is not completely idle, mainly improving the PPT and speeches reported at the MRS conference.

When Xu Qiu contributed to MRS, a lot of work had not yet been published, and now he wants to post the latest work progress.

Including Natural Energy and two Joule articles. Anyway, as an invited expert, I have 30 minutes of speech time, and I can talk more, so I don't have to worry about overtime.

As for the general content of the two contributions of Science and Nature, Xu Qiu also sorted them out, but they did not put them in the official report PPT. He planned to share these unpublished works with them if he met acquaintances. It's fine if you talk to strangers, but you must be on guard against others.

Speaking of which, Xu Qiu was still preparing for the return of the review comments of Science in the middle and late March, but now the review comments have not been returned until the end of March. This work has been reviewed for more than two months .

However, there is no way, who let him vote for Science.

The rest of the organic photovoltaic team continued their original experimental work after Xu Qiu completed the submission of the Nature article.

The articles of Han Jiaying's PTQ2 system have been sorted out and submitted to the target journal JACS.

Now the school girl has developed the ability to write articles. Compared with when she first joined the research group, her writing skills have improved a lot. Basically, the articles she writes do not need to be revised.

Next, Xuemei intends to continue the research on PTQ series donor materials. On the basis of PTQ1, fluorine atoms, chlorine atoms and alkoxyl side chains are respectively introduced into Q units to develop PTQ3, PTQ4, and PTQ5 donor materials.

Although the previous L2, L6, and S1 series materials also showed good performance, they are other people's systems after all, and it is okay to use them once in a while. If they are forced to study, it is a bit of malicious touch. necessary.

This is also the reason why large research groups in the scientific research circle generally focus on a certain subdivision field and will not easily change research fields.

If the direction is changed frequently, if the research directions of two large research groups accidentally overlap, it will cause a waste of scientific research resources.

Wu Shengnan is very happy recently.

Although Xu Qiu's two CNS-level articles are not secondary authors, she inherited nine Y-series materials, Y11-Y19, from Xu Qiu, and can sort out at least two or three AM-level works.

If it is exaggerated, the nine systems can even produce nine small articles in the second district. However, the pursuit of postdoctoral sisters has become higher now, and they are unwilling to go to the second district to write articles.

According to this development, Wu Shengnan has a chance to stay in school.

Of course, the high probability is still relatively difficult. Her situation and Xu Qiu's situation are still different.

On the one hand, it is his background. Xu Qiu’s masters and doctorates are all in Shanghai University of Magic City, belonging to the direct line of Shanghai University of Magic City, and the school where the post-doctoral senior sister has the first degree of undergraduate degree is still somewhat different from that of Shanghai University of Magic City. .

On the other hand, post-doctorate seniors do not have a job that can be one-shot. In other words, there is no CNS, and there is no job at the level of a major sub-journal of Nature.

Now the scientific research circle is getting more and more complicated. When Wei Xingsi returned to China, the era when a few AMs could be admitted to the University of Magic City has passed. If he returns to China now, he may only be able to enter an ordinary 985. The published work does not have N It is still difficult to get involved in the scientific research circle.

In addition, if the number of people staying in the same research group is too large, it may also cause some unfavorable effects, and the departments will also consider this factor.

Mo Wenlin continues to work on the preparation of Y series stacked devices, and now the device efficiency of this system has increased from the previous 15.5% to 16.0%.

The speed of performance increase has begun to slow down, and there is a high probability that the bottleneck has been reached.

Xu Qiu had already found the way to solve this problem, which is to develop Y-series materials with ultra-narrow bandgap.

Therefore, after discussions between Mo Wenlin and Wu Shengnan, they decided to try to develop an ultra-narrow bandgap Y-series material, named Y21, and apply it to stacked devices.
