Chapter 431: Work together

This week Xu Qiu is rarely "free" and has nothing to do with trivial matters.
So, from Monday to Thursday, he had four consecutive days of articles, and finally on Thursday night, he submitted the article "non-fullerene standard sample to scratch the effective layer" for the target journal AM.
In this article, he and Han Jiaying are the same, and the division of labor between the two is relatively clear. Xu Qiu proposed experimental ideas and wrote articles, and the school girl was responsible for the experiments.
After completing the submission, Wei Xingsi said with emotion: "Another AM submission, I remember that you also had an AM last month?"
Xu Qiu nodded and responded: "Yes, regarding translucent devices, we have reported the first high-efficiency translucent organic photovoltaic system."
"The problem shouldn't be big, and the opinions are coming back soon," Wei Xingsi finished speaking, and handed over a stack of documents: "You can read some recent documents. There are many good articles from other people."
Xu Qiu took the document, and Wei Xingsi pointed to the gift box in the corner and said, "Fang Guangwu brought me some lo-mei when he came back from a business trip. You can share it with the people in the group."
"Okay." Xu Qiu responded, then holding the document in his left hand and the lo-mei gift box in his right hand, returning to 216.
Entering 216, Xu Qiu put the gift box directly in front of Duan Yun: "Ms. Wei gave it to us to eat."
Duan Yun, who was originally a little depressed, saw the gift box and swept away the previous gloom, he smiled, his eyes shone, he started directly, and peeled off its clothes layer by layer...
The lo-mei gift box contains mainly "duck goods", including duck necks, duck feet, duck wing roots, duck gizzards, duck intestines, etc...
Xu Qiu took a box of duck necks, returned to his seat, and gnawed the duck necks with gloves while reading the literature.
As usual, he first ranks articles according to the influence of the journal, and then ranks the articles from high to low according to influence
There are indeed quite a few good articles recently. Although there is no orthodox
Nature
article above the magazine level, there is a
Joule
of comparable grade.
The research group who published this "Joule" article is Xu Zhenghong. They have developed a new derivative based on IDTBR material called IDTBR-CN.
The molecular structure of IDTBR-CN is similar to IDTBR. The central D unit and π unit have not changed at all. The only change is the introduction of two cyano groups on the end group of the A unit Rao Danning. This is why they added a "to the material name" -CN (cyano name suffix reason.
Xu Qiu took a closer look at their synthetic route and found that the synthetic idea of ​​IDTBR-CN molecule is very similar to that of ITIC. The method of introducing cyano groups also used malononitrile.
However, Xu Zhenghong and the others did not hide it, but rather generously pointed out the fact that "we have borrowed from the ICIN structure in the ITIC molecule" in the main text, and quoted several articles from the Wei Xingsi research group. Representative works include Xu Qiu's ITIC, and the early IDT-ICIN molecules of Sister Sister.
In the end, their device performance based on IDTBR-CN acceptor and P3HT donor materials, the efficiency broke through to 8%, and the device efficiency based on PCE10 donor materials broke through to 12%.
In addition, they have also done a lot of device stability research, including preparing the device in the air, applying continuous light to the device, storing the device in a glove box for a long time in the dark, and storing the device in the constant temperature and humidity air for a long time. The curve of photoelectric efficiency versus time is very detailed.
At the same time, the illustrations in their articles are really good. They are not directly derived from the ORIGIN software. They look very exquisite. Obviously they were produced after a second time. I don’t know if they are the drawings made by the students themselves or they are specialized. Find a company that undertakes this kind of business, or have a professional artist in your own group.

For large research groups, especially for research institutes with a large number of people, the division of labor unions is more detailed and specializes in raising a laboratory administrator, security officer, or art worker. This situation still exists.
Of course, even if you have your own art artist, you usually do it part-time. After all, a research group is not that easy to repair.
Just like Tian Qing in the group, she is usually busy with her own scientific research work. When it is necessary to make the cover of a cover article or submit a high-end article, she will be drawn and modified.
After reading the "Joule" article by Xu Zhenghong's group, Xu Qiu felt that it was okay on the whole, but he still felt that it was a little bit inferior.
Xu Qiu believes that it is normal for them to publish journals at the AM, EES, JACS, and NC levels. If they publish "Joule", it is a bit reluctant. After all, the 12% efficiency is not very competitive at this stage. , And he didn’t see much new things coming out in this article.
If you are a reviewer, you will probably reject the manuscript.
However, now that other people's articles have been published, Xu Qiu can't say much.
After all, there are many factors that affect the journal in which an article will be published. The quality of the article itself is only one factor. For most articles, this factor may account for less than 50%.
Xu Qiu also roughly analyzed the reasons why Xu Zhenghong's "Joule" article could be published:
It may be simply because of good luck, the reviewers I met are more NICE;
Or a large group of halo, the name of the boss is hung in the position of the corresponding author, who dares to reject my manuscript;
It may also be because the journal "Joule" focuses more on the field of organic photovoltaics and has lower requirements for the quality of articles in the field of organic photovoltaics. Similar to NC, it is more inclined to theoretical research than pure materials. Work is more welcome;
Or maybe "Joule" is a new journal, which is relatively short of manuscripts, and just invited Xu Zhenghong to contribute to their journal, just like Wei Xingsi was invited to write a review before;
It's also possible that "Joule" likes some gimmicky, bells and whistles. For example, Xu Zhenghong used concepts such as "classic donor P3HT" and "various stability tests", and made the article with pictures very delicate.
Thinking of this, Xu Qiu suddenly had an idea. No matter what the reason, the "full solution, colorful, translucent device" job that he had handed to the senior sister before was full of gimmicks. If Tian Qing help make some beautiful ones Perhaps you can also try to hit a wave of "Joules."
Now the impact factor of "Joule" is about to rush to 30. As long as the article can be hit, there is a high probability that you will not lose.
Moreover, Wei Xingsi's research group actually has a "big group halo." The previous "Joule" review was personally invited by the editor in chief. As long as the quality of the submitted manuscripts this time is not too hip, there is basically no problem in submitting the article for review.
This can be regarded as the default interpersonal relationship in the academic circle.
You invited me to contribute, and I responded to your call to submit your paper, so when you submit it again later, I have to give it some convenience.
A similar situation also includes the usual "gratis" review of manuscripts for journals, which seems to be free, but is actually paid.
When you review a lot of manuscripts for a certain journal, and then submit your article to this journal, as long as it is not the kind of article that will make people "reject at a glance," the editor will most likely give you a chance to submit it for review instead of rejecting it immediately.
It is important to know that many people submit manuscripts at the first step, that is, they are directly rejected by the editor after submission. The probability of direct rejection by editors of many journals is as high as 30%, or even more than 50%.
Of course, general favors will stop there. After the article is submitted for review, whether your peers will spray you into a sieve depends on the quality of your work.
In addition to Xu Zhenghong's "Joule", Gong Yuanjiang also published an ACSEL.
The research team of Gong Yuanjiang is doing this time is to design and synthesize small molecule donor materials, and combine them with non-fullerene receptors to realize photovoltaic applications.
They developed an organic small molecule donor material with metal zinc ion coordination, named Z7.
I have to say that this Z7 material is quite interesting.
On the one hand, its molecular structure is relatively unique. In the field of organic photovoltaics, it is not said that the molecular structure with coordination bonds is rare, but it is also not common.
On the other hand, the light absorption spectrum of organic photovoltaic materials is generally in the shape of a "convex" character, that is, a peak.
The light absorption spectrum of Gong Yuanjiang's Z7 molecule has a "concave" shape. Specifically, it absorbs light in the range of 400-600 nanometers, 800-1000 nanometers, and almost no light is absorbed in the middle 600-800 nanometers.
Therefore, this Z7 material can just complement the light absorption of ITIC, which has a light absorption range of 600-800 nanometers, and combine unevenness.
After thinking about it, Xu Qiu came up with the reason:
The material exhibits light absorption characteristics, mainly due to the existence of specific groups in the molecular structure. Then when there are two groups with large differences in light absorption properties in a photoelectric material at the same time, these two groups will naturally appear in the Z7 molecule. Absorption peak situation.
In addition, there are two AM work, one of which is the Lu Changjun research group of the Chinese Academy of Sciences.
This AM of theirs mainly focuses on the design and synthesis of polymer donor materials. UU Reading www.uukanshu.com also uses ITIC for acceptor materials.
There are a total of four newly developed donor materials, all of which are DA binary conjugated copolymers. The D unit uses BDT and TT, and the A unit uses TPD and TZNT. Then they are combined in pairs. Finally, the donor is studied. The change of the material's molecular structure will affect its intrinsic optical and electrical properties, as well as the morphology, transport and optoelectronic properties after blending with ITIC.
In the scientific research circle, different research groups encounter the same problem, and they can have different solutions.
For example, for the current efficiency breakthrough in the field of organic photovoltaics, Xu Qiu mainly focuses on the design and modification of acceptor molecules, while Lu Changjun and the others have a background in the development of polymer donor materials, and they tend to optimize through the design of donor structures. .
Speaking of which, some structural units in donor materials such as Xuemei H series and J series are relatively old structures. At the beginning, these structures were developed with the credit of Lu Changjun's research group.
On the whole, although there is competition among different research groups in the scientific research circle, in the same field, the general direction is that everyone works together to make progress.
