I Have a Research Support System

Monday morning, 9:40.

Eight members of the research team went to Caiyi 218 together, and found that Wei Xingsi was on the phone with someone, and raised his hand to signal to them, Sit down first, and wait for me for a while.

Like the last group meeting, Xu Qiu walked to the desk next to Wei Xingsi. There was a swivel chair here, which made it more comfortable to sit on. Others sat down in rows next to the large computer in the office.

Wei Xingsi didn't turn on the speakerphone, but Xu Qiu was relatively close to him, so he could tell that the person calling him was Gong Yuanjiang.

Wei Xingsi: Well, Mo Wenlin is doing pretty well, and now I've placed her in a postdoctoral fellow in our group for a temporary stay.

Gong Yuanjiang: That's good. By the way, you have seen Xu Zhenghong's EES article. The efficiency of their IDTBR system has broken 11%.

Wei Xingsi: Of course I saw it. The small boss in their group, Liang Haoxian, even sent me an email to show off the article. Don't talk about him. Xu Qiu told me a few days ago that Mo Wenlin came over and did it. A ternary system with an efficiency of 10.5%. I decided to give her this work and plan to vote for AM. The system is also quite simple. It is a donor and an acceptor developed by our group, plus PCBM...But it may take a while, our article on this binary system has not been published yet.

Gong Yuanjiang: Hey, just give me an AM? You guys are too fierce, are you hiding other big moves that haven't been released yet? Let me know, how far is the material development now?

Wei Xingsi: What's the big deal? We don't have many systems developed at the same time, just a few. Moreover, the highest efficiency of the system based on ICIN units is just over 10%. However, I think our ICIN series should be better than Xu Zhenghong's. Their BR system has more potential, and you can refer to the AEM we published earlier for the structure.

Gong Yuanjiang: Okay, okay, do you want to consider accepting a few more exchange students or something? I'm short of everything here, but there is no shortage of students...

Wei Xingsi: Hey, hey—hey, the signal doesn't seem to be very good. I'm going to hold a group meeting here. When you come to my side, I'll treat you well, so I'll hang up first.

Gong Yuanjiang:? ? ?

Everyone in the research group:? ? ?

It was the first time Xu Qiu saw Teacher Wei like this. It seemed that the relationship between him and Gong Yuanjiang was really good.

There was a wave of blowing on the friend's side, and Wei Xingsi was full of joy: Let's start the meeting.

After looking around at the people sitting in rows, Wei Xingsi asked, Wu Feifei, have you written your reply to the big revision of the AM?

Wu Feifei responded: It's still a little short, and it should be done tonight.

Okay, Wei Xingsi nodded, Finish it as soon as possible.

Wu Feifei previously contributed AM's article Isobutylamine Organic Spacer Layer Two-Dimensional Perovskite System. Xu Qiu helped analyze the GIWAXS data and also submitted a second work. However, the GIWAXS part he was in charge of did not have any problems, so the article was revised. The matter has nothing to do with him.

Wu Feifei began to report: Last week, the final efficiency of the two-dimensional perovskite system based on the p-phenylenediylamine organic spacer layer reached 11%. Now, except for the light source and TAS data, other characterizations have been prepared. The side has already sent samples, and they said they will arrange a test as soon as possible...

Seeing Teacher Wei turning his head, Xu Qiu knew that he was asking about the light source, so he took the initiative to add: The light source will be tested during the day on this Thursday.

Wei Xingsi gave a hmm and then said: This light source test, except for Duan Yun and Tian Qing, everyone else should go there, learn all the test methods first, and then use the shift system in the future, each time... four people .”

Okay. Xu Qiu replied, the shift of four people is relatively reasonable, just one car can fit in it, and their samples are generally not many, so it is enough for four people to alternately test.

Duan Yun’s JMCA article is preparing to finish, and another ACSAMI article is sorting out the data, but the latter ACSAMI, that is, the performance of thermoelectric devices after adding one- and two-dimensional materials is average, and the work’s novelty is also average. The article hits the street The probability is relatively high.

After Tian Qing's review article on Chem. Soc. Rev. was submitted, Wei Xingsi assigned her a new job, Mechanism research on two-dimensional perovskite materials with standard organic spacer layers such as n-butylamine and phenylethylamine.

Others in the group drew up a preliminary project direction by themselves, and then discussed with Wei Xingsi to improve the experimental plan, but Tian Qing was a special case, and the instructor directly arranged the project.

This is also Wei Xingsi's helpless move, because if she is not assigned a job, she will not spontaneously carry out the experiment...

Xu Qiu was mainly writing two articles last week, and he was interviewed when he took the time to get out of the circle. He designed a device with a new ITO pattern and tested it. There is no experimental data to report, so I will briefly talk about it. A few sentences: The new ITO pattern, the initial test result is about 10%-20% lower than the standard sample, but the sample data is insufficient, and further exploration is needed.

Chen Wanqing reported: The articles of the IEIC system are basically completed, only need to fill in the light source data.

The IEICO system has carried out a series of basic characterization tests, and its light absorption has been red-shifted compared with IEIC, and it has approached the near-infrared region...

Currently combined with the PCE10 system, the efficiency can reach up to 9.56%...

The further optimization direction is to further red-shift its light absorption by introducing electron-withdrawing groups, and plan to develop IEICO-4F/4Cl/DM, etc...

Xu Qiu muttered to himself below, he just mentioned it casually before, but the senior sister remembered it well, and directly brought out her previous thoughts.

Wei Xingsi said casually, Well, keep going.

Now Teacher Wei's presence in the group meeting is getting lower and lower. The main reason is that every student's work is proceeding steadily and orderly. It's a mess.

After all, he is not a front-line experimenter, and he is not necessarily better than the students in specific work experiments. At this time, it is a wise choice to choose to be a cheerleader and mascot.

Han Jiaying and Wu Shengnan synthesized H4x series donor materials and three acceptor materials IT-4F, IT-DM and FN-4F respectively last week.

It was originally planned to conduct device performance tests, but Xu Qiu requisitioned the glove box on Sunday to conduct device tests with new ITO patterns. Therefore, the devices of these systems have not had time to do it, and the two have no data to report.

Finally, Mo Wenlin appeared on the stage. The ternary system she was in charge of had already been reported to Mr. Wei, so she didn’t talk about it any more. Instead, she conducted a literature review report, which was also the first step that every newcomer had to go through.

The direction of the review was given by Xu Qiu, about the development of ternary blending systems in the field of organic photovoltaics in recent years.

She performed well in general, she was generous, and she was able to grasp the key points when reporting.

Because he is a new member, Wei Xingsi added a few words of encouragement, and kept asking warmly: Are you still used to coming to Shanghai?, How is the living?, Did Xu Qiu and the others teach you well?

Mo Wenlin responded with a smile: I have studied at Dongfa University for seven years, and I am quite used to living in Shanghai, Senior Wu Shengnan's dormitory is very good, Xu Qiu and the others treat me well. very good.

Xu Qiu silently complained beside him: Teacher Wei, stop pretending, you have already been exposed.
