The location of the weekly meeting was changed to a large conference room on the third floor of Caiyi.

This time, a few undergraduates also participated, and Wei Xingsi had a total of 14 people, which looked mighty.

Wei Xingsi first announced the good news in front of everyone: “Congratulations to Chen Wanqing for accepting the AM article. This is a 4,000 yuan bonus.”

This is mainly for a few new undergraduate students, telling them in a “favorable” way that as long as they post an article, they will get a bonus.

Although the elder sister’s article dragged on for nearly a week, fortunately, there were no moths in the end.

The elder sister successfully published an AM article, which can be regarded as completing an important career task during her PhD study.

As usual, Feifei Wu reported her first two-dimensional perovskite work based on thiophene ethylamine organic spacer layer. The article was published and the target journal AFM.

Next, she plans to take Yan Hu and Yu Ya to continue to study the two directions discussed with Xu Qiu.

“The work of the ITIC transport layer is relatively easy to do. You only need to do the test and characterization according to the standard process. It is currently in order…”

In terms of thinking, this work is a bit similar to Chen Wanqing’s use of perovskite materials as the transmission layer in organic photovoltaic standards.

In fact, it is the “crossover” between different disciplines. Now ITIC is more popular, so let’s take a bright spot.

It’s better to post an article like this. Even if you can’t post AM or JACS, it’s good to post a CM or JMCA level article.

The key is that the workload is not large, and there is no need to find additional highlights.

If it takes a month to stably publish an article in a weak area, most researchers are willing, and professors are no exception.

“Another work that spin-coated an organic photovoltaic system directly on the two-dimensional perovskite. When the organic photovoltaic layer is thicker, the performance of the device decreases, which may be blocking the charge transport of the perovskite, and when the thickness of the organic layer When thinning, the device performance will slightly improve…”

Feifei Wu thinks that the organic photovoltaic layer here may act as a transmission layer, but after all, it is a blended layer with a mixture of donor and acceptor, and it can still be regarded as an effective layer.

How to explain specifically, she decided to join forces with Swedish Feng Shengdong to test TAS to see if she could tell a good story.

For an article, “excellent performance” or “good story” always account for the same amount. In other words, even if the device performance is worse, as long as the story is well told, a good article can be posted.

Duan Yun did not report. With the publication of his last article, he is now in a state similar to a free man.

Although he is usually sent out to deal with school-related matters occasionally, the research work-related matters have basically been completed. Now, he only has to deal with the ACSAMI article that was submitted, or modify or transfer it until the article is accepted. until.

Graduate students or post-doctoral graduates generally do not leave behind jobs that have been voted out but have not been accepted until they graduate/leave the research group.

Once a small tail is left, it will be more troublesome.

If you don’t deal with it, the article will be regarded as “my own child”. I don’t care about others and may not help you manage it. If others manage it, it will be replaced as soon as it is done.

If it is dealt with, without the equipment of the research group, if it is necessary to supplement the experiment, it will definitely not be able to make it, and if everyone is gone, it is not necessarily happy to help the boss.

Therefore, some students who are close to graduation will “sell” articles that they have not had time to deal with, that is, deliberately submit manuscripts to journals that are inferior to the grade, and strive to get the article accepted quickly, so that there is no need to modify or wait.

Duan Yun still has a lot of time, nearly half a year, and he is not in a hurry. For him, the top priority now is to find a job and get an offer.

It’s almost November now, and the large wave of resumes that Duan Yun cast out before has begun to have responses one after another.

In addition to ExxonMobil in the first round of testing on Friday, Dow Chemical, Warwick and other companies also sent Duan Yun an invitation for the first round of testing. After all, he is a doctoral student at Magic University, a top 5 school in China. It is not difficult to qualify for the first round of testing if you want to pass the resume screening.

The difficult thing is whether to enter the second and third rounds.

One of the disadvantages of Duan Yun is that he is a bit older, because he has worked for several years after graduating from his master’s degree, so he is now in his 30s.

The same Ph.D. graduates have similar qualifications, with an age of 30+, and a normal person of about 27 or 28. Unless they are experienced in technical positions, most companies will choose younger ones in other cases.

The performance of age discrimination among men is actually good. If you join a woman, a female doctor of about 30 years old, the company may consider many situations:

If you are single, the company will feel that you have a personality problem, otherwise why not get married? Will you get married after a while, will you take marriage leave and maternity leave? Work for a few months, leave for a whole year?

If you are married and have no children, the company will feel that you are about to give birth to a child, and then take maternity leave? Work for a few months in the same way, take leave for a whole year?

If you are married and have children, the business side will feel that you have a child. Are you busy with your family? Can you devote normal energy to your career? I have doubled the work, and will I only get half a person in the end?

This is where the female doctor is more embarrassing.

Of course, the elder sister does not need to consider these issues. Now she is basically connected to the Blue River. The company has Xu Qiu’s shareholding, and it shouldn’t be closed immediately.

Sun Wo began to write his first article, on “The influence of different processing technology in the two-dimensional perovskite standard sample system on the device morphology”, the target journal ACSAMI, the progress is relatively slow, a week has passed, only 10% completed about.

Wei Xingsi is not harsh, but encourages Sun Wo to “continue to cheer” because he knows that for novices, the first article does not count as time for experimentation. It takes one or two months to write and modify the article alone. These are all normal things.

Tian Qing continued to write the work of “Multiple systems of exciton binding energy and exciton diffusion distance”, the target journal ACSEL, the progress of the article is about 70%, she has some strokes, and there is no code word to go all out, otherwise according to her ability , This week’s article progress is estimated to reach 80%, or more than 90%.

Chen Wanqing began to report: “Last week, we mainly prepared all-solution translucent devices on the Blue River side, and replaced the PEIE transmission layer material. The device efficiency broke through to 7.17%…”

“At the same time, we tested and compared the molecular stacking structure of the thin film prepared by spin coating or scraping with the same effective layer material in the QuMudu light source test…”

“The data is integrated in-plane and out-of-plane, and the results show that the (100) and (010) signals of the film obtained by blade coating are stronger than those obtained by spin coating…”

“It can be explained that the squeegee is a slow moving squeegee, and the film naturally forms a film. The time for crystallization in this process is very sufficient, and it is easier to form a highly crystalline film. During the spin coating process, the film is on a high-speed rotating platform. When the solvent evaporates, the film-forming time is very long, which is not conducive to crystallization…”

“In addition, this is the light absorption spectrum…”

Seeing that Xuejie only listed the light absorption image of the effective layer film, Xu Qiu suggested: “You can compare the light absorption spectra of the effective layer film obtained by the two preparation methods of scraping and spin coating. I mean Compare in the same picture to see if there are any differences.”

Chen Wanqing thought a little, and nodded: “Okay, I will draw them together and compare them.”

“Well, I speculate that the position of the absorption peak of the light absorption spectrum of the scratch coating method may be red-shifted relative to the absorption peak of the spin coating method, and theoretically the peak should be more’sharp’, that is, the half-value width will be smaller. “Xu Qiu first added a few words, and then changed the subject: “Of course, if the experiment results are not like this, then I don’t say it.”

Everyone originally thought that Xu Qiu’s analysis was very reasonable after listening to the first half, but they didn’t expect to add such a sentence at the end, and they all laughed.

Xu Qiu’s “Joule” review has been initially written, and the finalization and article revision are in progress. It is expected to be published this week.

He and Wei Xingsi are the only authors of this article. You can’t ask other people to help revise this article. Before consulting Teacher Wei, I have to read it a few times.

Han Jiaying completed the synthesis of H5 and J4 materials last week, and made a batch of devices at the weekend, using receptor materials such as IT-4F and IDIC-4F to match them.

The results show that the device performance of H5 material is about 1% lower than that of H22, while the performance of J4 and J2 has not changed much. Xu Qiu has repeated experiments in the simulation laboratory, which also confirms that the school girl is in Experimental results in reality.

Among them, for the work of ~www.mtlnovel.com~, there is a high probability that no very good articles will be published. The upper limit is almost a weak area, or if an AM sub-journal is concerned, there is hope to publish an AM-level article, although the device performance has not been significantly improved However, the idea of ​​replacing fluorine atoms with chlorine atoms has solved the problem of difficulty in material synthesis, which is also a big bright spot.

Wu Shengnan’s IDIC-M article has been written and submitted, and the target journal is EES.

In addition, she got two new materials, IHIC and 4TIC, both of which were modified with the conjugate structure of the D unit relative to ITIC, and the goal was to obtain a narrow band gap near-infrared light absorption acceptor.

The final result is not surprising. The light absorption edge of the two materials is around 900-1000 nm, and the device performance is quite satisfactory. The combination of the two acceptors and PCE10 and PCE11 donor materials can achieve a maximum efficiency of more than 10%.

The postdoctoral sister is planning to move towards translucent devices next. Xu Qiu has already paved the way for her in advance, and the difficulty of exploring experimental conditions has dropped a lot.

Mo Wenlin continues to write her third ternary article, the target journal AEM, and the progress is now about 50%. Xu Qiu didn’t bother her much last week, and her writing speed has also increased.
