Chapter 410: Sister got what she wanted?

At about 3 in the afternoon, Chen Wanqing was called to the office by Wei Xingsi, and her comments on the AM article of the -4F system returned.
The comments of the two reviewers are positive, and the comments given by the editor are minor changes, no additional experiments are required, and there are no difficult questions to answer.

Seeing this result, the elder sister burst into tears of excitement: "It should be stable this time, it's really difficult to post an AM."
Xu Qiu leaned over to look at the opinions and said in a positive tone: "Stabilize, stabilize. If you can't publish it like this, I will eat something, butterfly swim in something, pull something upside down..."
Chen Wanqing shrank her head and said, "You me so much, I'm a little panicked..."
"Don't panic, I'll help you change it again after you finish it." Xu Qiu said actively.
"Okay." Chen Wanqing smiled.
In the evening, Xu Qiu helped the senior sister to revise her revised draft and comment response document, and then submitted it to Teacher Wei.
On Tuesday, Chen Wanqing took Han Jiaying to Blue River to continue the scratch coating experiment.
This time, the device efficiency of the all-solution method has been further improved, breaking through 7%.
It's not because of the improvement in the operation method or the squeegee equipment, but because Blue River purchased a transmission layer material called polyethoxyethylene imine (PEIE).
Compared with the previously used PFN material, this material is more suitable for the blade coating system, and it is easier to obtain a uniform and dense transport layer film.
I have to say that the banknote ability is quite powerful.
The words that Blue River previously released were "As long as it is possible to improve the performance of materials, we will find channels to buy some and try them", and it really works now.
Even the efficiency of the device prepared by Han Jiaying that only scratched the effective layer has reached 9%, which is about to approach the 10% mark.
In addition, Yang Qin and the others have completed synthesis experiments including ITIC, 4F and other materials, and conducted device tests.
Although the device efficiency does not fully repeat the value in Xu Qiu's literature, it is not much different. The overall deviation value is 0.5%-2%, which is still acceptable.
Deviations are very normal, because Xu Qiu's experimental conditions were established through constant exploration and were only applicable to the current instrument state of the Wei Xingsi research group.
Moving to other places, even with the same system, the optimal conditions will change. Even with the help of school sisters, it is impossible to get the optimal results all at once.
Therefore, Yang Qin also contacted Xu Qiu to discuss the sale of materials.
Xu Qiu gave Yang Qin two sets of documents, one set is the ITIC-related documents published by the research group, and the other set is all the documents in the field of organic photovoltaics in the past two or three years.
The next task for Yang Qin is to find the contact information of the corresponding authors of each research group in these documents, and then sell them through mass emails.
The mass mailing will consist of four parts:
The first part is a summary of recent major documents, which is to summarize the main content of an article in one sentence.
It is similar to: "The synthesized XX material is different from the original YY material? What are the improvements compared to the original system? What are the reasons..." After that, the DOI number will be attached to facilitate colleagues to find this document.
It is also reminding them not to forget to cite the article when using our materials.
In theory, this part is to summarize all ITIC-related documents, including articles from other research groups, but in reality Xu Qiu intends to only put articles in his own research group.
On the one hand, he and Mr. Wei invested in Blue River Optoelectronics Material Company. They are my own family members and must give priority to promoting themselves;
On the other hand, in the current ITIC system, there is not much work done by other research groups, including Gong Yuanjiang, although he also published two AM articles, but the core is mainly on the whole small molecule system, not the non-fullerene receptor material. itself.
The second part is the product catalog and quotation.
Xu Qiu didn't plan to manage this personally, and directly forwarded the product catalog of Shencheng Optoelectronics Company to Yang Qin, and asked him to make a similar one.
Xu Qiu additionally urged Yang Qin that prices should be as consistent as possible with Shencheng Optoelectronics, not too high or too low, and it is best to be basically the same.
Then at the beginning of the opening, discounts such as 12% off can be provided, which is slightly cheaper than other homes.
The premiums of various materials in scientific research circles are generally very high, but people still eat this set.
If your materials are much cheaper than others, it may also make people feel that your things are not very good and the quality is problematic.
In fact, the main reason is that there are relatively few customers, and the road of small profits but quick turnover does not work.
Maybe when a customer disappears, we must shovel some wool down on them before they disappear.
The third part is the characterization test of materials. Monomers and finished materials must be characterized by liquid chromatography and infrared spectroscopy to characterize their purity. The finished materials must be supplemented with the JV curve of the device, indicating that our batch of materials will be shipped. The device efficiency can be at least as much as possible.
Xu Qiu took a look and found that the device efficiency of the first batch of ITIC materials to be sold has been able to stabilize more than 10%, and the device efficiency of -4F material can be more than 11%, and the purity of the material is more than 99%.
For example, Shencheng Optoelectronics does not indicate device efficiency data when selling materials, and some do not even indicate purity.
If a new customer encounters these two optoelectronic companies, they will most likely choose the one with the device efficiency, because there is a guarantee, and this guarantee is not low.
11% efficiency, buy the materials back, just find some other materials to mix, it is not difficult to write a small article in the second district.
In addition, Blue River Optoelectronics is currently the only company selling series of materials, which is also a great advantage.
However, the dominance period will not be too long, and may be at most one or two months.
Time has dragged on, and other companies will follow up with these materials.
After all, there is no patent protection, papers are public, anyone can synthesize them and sell them.
The fourth part indicates that Blue River Optoelectronics and the Wei Xingsi research group of Modu Comprehensive University have cooperation, and at the same time, they will provide high-quality after-sales service. Any problems encountered in device preparation can be communicated at any time, and we will serve you wholeheartedly.
Here are some polite remarks. There are basically no 7 days for unreasonable returns in the scientific research circle. First say good things to fool you when you bought them. As for the after-sales service, look at your mood.
Of course, you still have to maintain a "good mood" at the beginning, after all, you have to accumulate customers.
The only problem at the moment is that the article of Xuejie-4F has not been officially published. When propagating -4F, the referenced documents can only be temporarily empty, and we will talk about it after the article is published.
In the past few days, Xu Qiu's main job is to write a review of "Joule".
On Wednesday night, the overall progress of his article reached about 70%. The previous "review" part has been basically completed, except for the later "view" part. This is also the core of this article and needs to be refined.
On Thursday, the light source test.
Xu Qiu didn't go because he was going to class, but this didn't affect the smooth progress of other people's experiments.
Now, the combat effectiveness of the organic photovoltaic team has become very powerful. Everyone has the ability to be unique. Even if they leave Xu Qiu's backbone for a while, they can still operate normally.
In this test, Han Jiaying and Chen Wanqing carried the film prepared by blade coating. It is said that the GIWAXS and R-SoXS results obtained on site are significantly different from the previous spin coating test results, but the data has not been processed yet.
On Friday, the senior sister's comments on the revision of the AM article still did not come back. Chen Wanqing looked quite calm on the surface, but she didn't know what her true thoughts were.
By convention, if the first review of the article is a minor revision, and the reviewers’ comments are relatively positive, if the editor thinks the revised manuscript is good, the article will be accepted directly within two or three working days.
Four days have passed, and there is still no news. There are two possibilities:
One is that the editor has been busy recently and has not seen the revised draft;
The other is that the editor reads the revised manuscript, but is not sure whether to accept the article, so he sends the article to the reviewer for re-review.
As for the specific type, it is not known.
On Friday afternoon, close to get off work, everyone was sitting around their desks.
Duan Yun suddenly said mysteriously: "Everyone is free tonight, don't hurry to leave after get off work, I have something to ask you."
Chen Wanqing raised her head, then lowered her head again without responding.
Xu Qiu asked curiously: "What's the matter?"
"I voted for a bunch of resumes before, and I finally got one back today." Duan Yun explained with a smile: "It's ExxonMobil's first round of school recruitment test. It needs to be answered online. My roommate said that this kind of test is a problem. The difficulty is not low, UU reading www.uukanshu.com I am afraid I can't handle it alone, so I want to find some helpers to help me."
Xu Qiu asked: "I heard that this kind of online test requires a camera, right? You won't be caught?"
"Some need to turn on the camera, and some don't. I'm also the first time to participate. I'm not sure." Duan Yun shook his head, and then said: "But even if you need to turn on the camera, you can help me by your side. As long as it doesn’t appear in the lens."
It was the first time that Xu Qiu came into contact with the school recruitment test, and he immediately became interested: "When will it start?"
Duan Yun checked the email and said, "It's seven o'clock in the evening."
Xu Qiu turned to look at Han Jiaying, made eye contact with the school girl, nodded knowingly when she saw her, and said, "Brother Duan Yun, I will help you after dinner with Han Jiaying tonight."
"Great," Duan Yun said happily: "At that time, we will each prepare an experiment log for drafting, while keeping the computer always on, ready to use the search engine at any time."
"No problem." Xu Qiu nodded in response.
