I Have a Research Support System
Chapter 255 People sit at home, but articles come from heaven (for subscription)
On Friday morning, Xu Qiu entered the simulation laboratory II to check the photoelectric performance data of the senior sister's IDT-ICIN system.
After seeing the result, Xu Qiu stiffened slightly, no, he was slightly surprised.
The highest efficiency is actually 5.48%!
In the last IDT-IN system, it was only 2.87%, but this time it has almost doubled.
The key point is that the world record for photoelectric conversion efficiency of the current A-D-A type of non-fullerene system is only about 6%.
Of course, this is related to the fact that the field of A-D-A has just emerged. It has only a few years of research history, unlike the PDI system and the fullerene derivative system, which have been studied for more than ten or twenty years.
After being surprised, Xu Qiu discovered a rather embarrassing question.
For the new system of the senior sister, the efficiency range is within 4%-7%, and the upper limit of articles that can be published is actually fixed, basically stuck in the top journals of chemistry and materials such as AM, JACS, and EES .
It is nothing more than the higher the efficiency, the higher the probability of the article being accepted. If it can break through the existing record of 6%, it is about equal to stabilizing an AM. If it cannot break the record, for example, if there is an efficiency of about 5%, the article is well written and published. The probability of AM is also eighty to ninety percent.
But if you want to go further and publish the sub-journals of "Nature" and "Science", you must compete with other non-fullerene systems, that is, to compete with Xu Qiu's PDI system, and it must reach more than 8%... Now it is more than 8.4%.
Of course, these are articles aimed at mainstream sprint efficiency, and there are also other methods, such as putting the name of a big boss or something...
In any case, based on the current results, it should be safe for the senior sister to write an AM, unless someone else first reported the similar A-D-A receptor material based on ICIN, then it can only be said that there is no fate.
After analyzing it for the senior sister, Xu Qiu took a look at the bottle containing IDT-ICIN. It was different from the deep red 3D-PDI material he synthesized. The senior sister's material was a dark brown powder with a brown color. Very light, more black, somewhat similar to the color of PCBM, a fullerene derivative.
Xu Qiu casually threw the bottle away, and the glass bottle entered the glove box through the glass, and then he began to check the detailed experimental data.
For IDT-ICIN non-fullerene acceptor materials, the best matching donor is FTAZ with a wide band gap, and the second best matching donor is PCE10.
This is not surprising, and is consistent with the results of the last IDT-IN system.
However, the two results are still different. This time, the highest efficiency based on PCE10 is only 3.94%, which is far from the former 5.48%.
Xu Qiu thought to himself, at this time, if there are other wide-bandgap donor materials, or try several systems, the efficiency can be even higher, maybe it will directly break 6%.
It's a pity that I only have FTAZ for the time being. It seems that we still have to enrich the types of polymer donor materials in the future.
However, for this kind of thing, it is definitely not enough to rely on his own strength. It is necessary to mobilize scientific researchers in the entire field to work together.
The specific operation is not difficult, just need to develop a kind of star material, high-end articles are hung there, and people will naturally be moved by it.
The academic circle is very pure, if you let me post articles, I will follow you (direction).
If the senior sister’s IDT-ICIN material publishes high-end articles such as AM, many researchers will naturally develop matching wide-bandgap polymer donor materials and prepare similar structures based on the senior sister’s IDT-ICIN material A-D-A non-fullerene acceptor molecules.
Just like the AM article posted by Xu Qiu before, after reporting a new type of donor material PCE11, many people followed suit.
Even the optoelectronic material company in Shencheng kept pace with the times, synthesized PCE11 for sale, and sold it to him.
Moreover, Xu Qiu searched for the title of his AM article on the academic mirror of Google Dog some time ago, and found that the number of real-time citations of the article has reached 16 times.
You must know that the impact factor of AM is only more than 20, and the impact factor of journals is usually calculated as the average number of citations of articles published within two years.
And Xu Qiu's article has just been published, and it has only been published for half a year.
According to the current development situation, the number of citations of his article will definitely exceed the impact factor of the AM journal itself by a lot.
It was selected as the cover article before, and it is estimated that to a large extent, it is also because this article has attracted the attention of many researchers recently.
Teacher Wei has received four review articles on the PCE11 system.
The first one was from Yan Hu’s research group who had a collision with Xu Qiu before. They submitted to JACS. Because the content of the work was basically the same as his AM, Xu Qiu directly rejected the paper.
The second one is the review of JMCA. They mainly synthesized a new A-D-A type non-fullerene acceptor of Rao tannin system, using Xu Qiu’s PCE11 molecule as the benchmark donor material, and the efficiency is quite satisfactory, about 4%, Xu Qiu I gave them a suggestion for a minor revision, and their article was successfully published later.
The other two were reviewers of small journals in SCI District 3 and District 4, and Mr. Wei directly rejected them.
It's not that the article was rejected, but the editor's review request was declined. Wei Xingsi didn't accept all reviewers from any journal, only the reviewers from the journals he would submit to would be interested.
This can be regarded as an unspoken rule in the industry. As a scientific researcher, if you help the editor review a lot, you can get acquainted with the editor. When you submit a manuscript next time, unless the quality of the article is too poor, otherwise the editor will There is a high probability that you will also be given a chance to submit your manuscript for review, so that you will not reject the manuscript directly.
This is a world full of PY, and foreigners are not so rigid, and to a certain extent, they can also talk about human feelings.
In addition to the four articles that Mr. Wei encountered when reviewing manuscripts, there are many "fish that slipped through the net" that other reviewers reviewed.
Not to mention the articles in the third and fourth districts of SCI, just published in the journals of the first and second districts, Mr. Wei downloaded a total of eleven related articles.
Five papers are from the research group, including two papers by Xu Qiu, respectively, on the original PB4T material and the side chain regulation of PCE11, two papers on the P3T and P5T systems, and one paper on the crystallinity of the PCE11 system .
Among the remaining six papers of other research groups, one is based on PCE11 to make a ternary blending system, which is similar to what my senior sister used to do;
One article made some fine-tuning on the basis of the molecular structure of PCE11, and synthesized a semi-new structure, similar to the P3T and P5T made by the school girl;
Two other articles were inserted in the introduction part when referring to the recent progress in the field of organic photovoltaics, and PCE11 materials were not used in the main text;
As for the last two articles, they are from Yan Hu's research group.
I don't know how Yan Hu felt when he submitted an article. He could happily win the first place, waiting for others to cite his own article, but he wanted to cite someone else's because he was one step late, and JACS was gone.
As the saying goes, if you lag behind, you will be beaten. In the academic circle, if you lag behind, you will quote other people's articles.
...
After Xu Qiu carefully studied the data in the simulation laboratory, he discovered another phenomenon, but it was not based on the senior sister's system, but about the simulation laboratory itself:
As his device preparation technology becomes more and more proficient, the intelligence of simulation experimenters is getting higher and higher.
In other words, the preliminary exploration results given by the simulation experiment system are getting closer and closer to the real photoelectric performance of the material.
However, there are gains and losses, because there are more conditions for exploration, and the time consumed has also increased. Just like this initial exploration, it took about seven hours. Usually, a single system only takes about four to six hours. For more refined exploration experiments, the time will be further extended.
Fortunately, some exploration results can be used repeatedly, such as the thickness of molybdenum trioxide and the processing conditions of the zinc oxide layer. These optimizations for the device transmission layer are common to most systems.
Generally speaking, Xu Qiu is constantly improving, and any form of his progress will be simultaneously fed back to the simulation laboratory.
Xu Qiu couldn't help thinking that one day in the future, his experimental skills will be perfected, and the donor receptor bank in the system will be complete.
Once the newly synthesized organic photovoltaic materials are sent to the system, within a day, the best device processing conditions and device performance can be directly obtained.
It would be great if the simulation experimenters could also automatically process data, draw graphs, write articles, cite references, and submit articles...
People sit at home, and articles come from heaven.
Ah, I seem to be thinking of peaches.
Xu Qiu shook off the unrealistic fantasy in his mind and exited the simulation laboratory.
Afterwards, he bounced off the bed, washed up briefly, did morning exercises and had breakfast with his junior, and then sent the junior to the school bus, while he strolled to Caiyi.
When he arrived at Caiyi 216, it was about 9:20, and there were already many people in the office.
Xu Qiu looked around, Tian Qing was operating the ORIGIN software, apparently processing data, Duan Yun was doing experiments in the inner laboratory, and Chen Wanqing was sitting at the desk in a daze.
Thinking of the results of the simulation lab in the morning, Xu Qiu went to sit next to Chen Wanqing and smiled mysteriously at her senior.
The senior sister blinked and blinked her eyes, she didn't know why and said, "What are you laughing at?"
Xu Qiu smiled and said nothing, he hadn't considered how to tell her the good news.
Chen Wanqing also responded with a smile: "By the way, don't forget to help me make devices, please."
"Okay," Xu Qiu nodded and said, "Then I'll make a solution now." After speaking, he got up and went to the inner laboratory.
After much deliberation, Xu Qiu decided to experiment with the PCE10 system first.
Although the efficiency is only about 4%, it is not too low. At least it can give the senior sister the motivation to continue optimizing the molecular structure.
Afterwards, she can be slowly guided to consider light absorption and complementarity, and let her personally "discover" wide-bandgap donors such as PTAZ, which is safer.
After preparing the solution, Xu Qiu began to spin-coat, vapor-deposit, and test the device. At the same time, he did not stop writing the article, and took the time to complete the abstract, conclusion, and introduction.
At four o'clock in the afternoon, Teacher Wei appeared at the door of 216 with a green suitcase.
