I Have a Research Support System

Xu Qiu returned to 216 and began to prepare the PPT needed for the conference.

This conference was different from the one they had attended at Gong Yuanjiang's side at Kainan University before.

At that time, the number of articles in the research group was limited, only a few.

Therefore, at that time, Wei Xingsi directly put all the work, even the less relevant PDI and PCE11, side by side, and talked about it all at once.

Now, there are a lot of articles related to organic photovoltaics in the group, reaching about 30 articles.

If you talk about everything in detail, you won't be able to finish it in an hour.

Therefore, there is a need to make a choice, and I will focus on a few representative works, and I can only briefly mention other works.

Moreover, the current work is systematic, and it is also necessary to build a good story line and connect them in series, so that it can be easily told to colleagues.

When the research group develops to a certain level in a certain field, it must start to establish its own system and create a series of work.

When someone mentions a certain material or a certain type of material, they can think of the corresponding research group: "XX is the material of the XX research group."

This is very important. On the one hand, it can increase the influence of the research group in the field; on the other hand, from a utilitarian point of view, it can also make it easier for the research group to survive and grow stronger.

Because if you keep digging a series, you can form a small barrier, so that your research group can maintain an advantage in this series, so that there will be no sudden fault in the article, and there is an expectation of the output of the article, and it is easier to attract graduate students and postdoctoral fellows. .

For example, Xu Qiu has many ideas in his mind, about Y-series receptors, about stacking, and about translucent devices.

From his point of view, these ideas are easy to come up with. If you try, it is very easy to produce scientific research results, but other research groups may need to spend several times as much time as him if you want to think about them. This is the existence of barriers.

The theme of Xu Qiu's speech at this conference is relatively easy to establish.

The previous research on the PDI system has been temporarily abandoned, and the subsequent Y-series receptor articles have not been published, and they need to be hidden. These are not suitable.

So definitely around the ITIC series of non-fullerene acceptors.

Since it is the ITIC series...

Xu Qiu suddenly had an idea, thinking of the previously published "Joule" review article, it seems that it can be used directly, and it fits the scene in front of him very well.

Therefore, he decided to plan the sequence of his reports by referring to the story line summarized in "Joule". He only needs to grasp the details of each part, that is, the approximate reporting time of each task.

Xu Qiu created a blank PPT file, intending to make a whiteboard PPT first, and then apply a ready-made template.

For templates, you can contact Tian Qing. She has collected a lot of PPT templates. It is said that she has paid for PPT templates online before.

In this regard, Xu Qiu said that we don't understand the world of rich women. If it were him, there would be a high probability that he would "do it by himself and have enough food and clothing".

The PPT on the first page is naturally the cover. Xu Qiu casually wrote the title "Development of ITIC Series Non-Fullerene Solar Cells", and then wrote down the reporter "Xu Qiu" and the reporting time "December 14th". The school name and school emblem LOGO of Shangmodu Comprehensive University.

The second page is the table of contents, which is left blank for now.

Xu Qiu started planning from the main text on the third page. He planned to take the summary of "Joule" first, and put a screenshot and TOC of the article, which took about 30 seconds to introduce.

Another review, that is, the non-fullerene review previously published on ACSEL, does not need to be mentioned, and it is not highly relevant to the ITIC series.

The next step is the specific experimental work.

First of all, it is the AEM article of the senior sister, which developed the IDT-ICIN material.

This is also the origin of ITIC. Although the performance of the device at that time was not high, it was the first time that ICIN, the A-unit terminal group, was reported and later used in more than a dozen materials.

Xu Qiu doesn't plan to spend too much time on this work. He mainly introduces the structure of ICIN and the problems existing in IDT-ICIN materials, paving the way for the introduction of ITIC. The introduction time is tentatively scheduled for 1 minute.

Then, Xu Qiu’s AM article and Xuemei’s JACS article developed ITIC, and combined it with the traditional narrow-bandgap PCE10 donor and the emerging wide-bandgap donor H22, the efficiency broke through all the way, from 8% to 10 %.

This part is a sign that the ITIC series is emerging. You can talk about it a little more. Xu Qiu reserved about 3 minutes.

Next, for ITIC, Xu Qiu led the organic photovoltaic team of the research group to improve it through four paths, namely:

The modification of the terminal group of A unit has developed several representative derivatives, mainly the work of Xu Qiu, including IT-M, IT-4Cl and IT-4F, etc.;

The modification of the conjugated unit of the D unit is mainly the work of Wu Shengnan, including FNIC, etc.;

The modification of the side chain of the D unit is mainly the work of Xu Qiu, including IDIC, ITIC-Th, m-ITIC, etc.;

Drawing on the idea of ​​Xu Zhenghong's research group IDTBR, the development of the AπDπA structure is mainly the work of Chen Wanqing, including IEICO.

Each part is tentatively scheduled for 2 minutes, adding up to a total of 8 minutes.

Among them, use 1.5 minutes to focus on one of the representative works, and the other 30 minutes to briefly introduce other works of the same type, simply mentioning the name.

Then, there are further studies on these four paths, that is, the mutual intersection and expansion of the four paths.

The modification of the end group of the A unit is widely used in other systems.

The most eye-catching in the early stage is the fluorine-substituted ICIN-2F end group, which is used in FN-4F, IEICO-4F and other systems.

Afterwards, chlorine-substituted ICIN-2Cl came from behind, which not only greatly reduced the synthesis steps, but also maintained the photoelectric performance without significant reduction.

The highlight time system of ICIN-2Cl is in the Y-series receptors, so it must not be reported here.

Therefore, Xu Qiu planned to bring the senior sister's IEICO-4Cl and talk about it, tentatively for 1 minute.

The modification of the conjugated unit of the D unit was further extended to later translucent devices, as well as Y series materials.

The Y series materials cannot be reported. Xu Qiu chose the FN-4F material developed by her post-doctorate sister for translucent devices. This part is tentatively scheduled for 1 minute.

The modification of the side chain of the D unit, the IDIC system stands out, and becomes the first ITIC derivative acceptor that can be used to prepare large-scale, thick-film devices, tentatively for 1 minute.

After further optimization, the obtained IDIC-4F has an efficiency of 13.5%, setting a world record for efficiency in the field of organic photovoltaics.

Xu Qiu was a little conflicted, whether to tell this work, after all, the article has not been officially accepted yet, it is a little risky, but as the host's report, there must be some work that can shake the field, otherwise all of them will be published Work, that's too mundane.

After thinking about it for a while, Xu Qiu decided to put this part in the PPT first. After writing the details, he can find Wei Xingsi and listen to his opinions.

This part of the work is very important, and there is a lot of content. Xu Qiu directly arranged the longest time, tentatively 5 minutes.

The AπDπA structure, the IEICO series of acceptors, and the IEICO-4F material in it are further extended to semi-transparent devices, which is the AM article that has just been accepted, tentatively for 1 minute.

In addition to the modification of ITIC series acceptors, there is also the development of donor materials, which is mainly the work of Han Jiaying.

Including the synthesis of wide bandgap donor materials of H series and J series, each part takes 1 minute tentatively, adding up to 2 minutes in total.

In addition, there is Mo Wenlin's ternary system. There are three ternary systems in total, namely 2D/1A type, 1D/1NFA (non-fullerene acceptor)/1FA (fullerene acceptor) type and 1D /2NFA type, add up to 2 minutes.

These are all related to ITIC, but not directly related to the acceptor material, so Xu Qiu doesn't plan to spend too much time on it.

Finally, the outlook part, this part Xu Qiu arranged for a total of 5 minutes, mainly referring to some ideas in the previous "Joule" review, and made some additional minor modifications.

Except for some specific and feasible scrap work that Xu Qiu gave up due to insufficient manpower in the team, the other parts are Xu Qiu's vision for the field of organic photovoltaics. The overall goal is to clear the way for commercialization.

Xu Qiu still maintains his previous thinking—now that he has the ability and influence, he should show his perspective to his peers and lead them to the path that Xu Qiu believes is correct.

The development of human society to the present, most of the period is a small group of pioneers, to lead the majority of ordinary people forward.

After planning the story line of the conference speech PPT, Xu Qiu added up the estimated time for each part.

The total time is estimated to be 30 minutes and 30 seconds, which is just right.

At this time, Wu Feifei came in from the outside, holding three postal EMS express envelopes in her hand, and said to Xu Qiu and Han Jiaying: "I just went to the concierge to pick up the express, and the passports of the three of us have already been mailed back. "

"Thank you." Xu Qiu took his envelope, opened it and took out his passport, only to find that the visa had been affixed on page 39 of the passport.

The visa is in English, which is somewhat similar to the style of a passport/ID card.

In the upper left corner is a white "VISA (visa)" on a blue background, and in the upper right corner is the full spelling of the beautiful country USA.

On the left is a black and white photo of the US visa, and on the right is various information, including the place of visa issuance, visa number, name, passport number, gender, date of birth, visa type, nationality..., and the validity period of the visa. Expires on November 29, 202x.

Seeing that Xu Qiu and the others had obtained their passports, Tian Qing came over and asked, "How long is your visa valid for?"

Xu Qiu responded, "Ten years."

Han Jiaying answered, "Me too."

Wu Feifei smiled: "Me too."

Tian Qing's expression was strange: "Uh...you are all ten years old?"

The three of Xu Qiu nodded in response, and Tian Qing exclaimed: "It's amazing, it's been ten years, by the way, don't forget to update the EVUS information."

Xu Qiu originally wanted to say something: "The agreed five-year period is very long."

But after thinking about it, I still didn't make up the knife.

On the previous page of the visa page in the passport, that is, page 38, there is also a blue stamp and a sticker that read:

"All travelers who hold a florist passport and hold a 10-year valid B1/B2, B1 or B2 Beautiful Country visa must enter the electronic visa renewal system. EVUS website for information registration. For more information about this project, please visit

For information registration, please visit:

"

The following is the introduction of the English version. The full name of EVUS is Electronic Visa Update System (Visa Update Electronic System), and there is a big EVUS icon and a QR code.

Xu Qiu wanted to complain about the broken sentences and punctuation marks in the Chinese part. I'm afraid the staff didn't translate it directly from Gugou, and probably didn't check it carefully.

Because of Arita Haru's previous reminder, Xu Qiu didn't use Qiandu search to enter EVUS, but directly typed the URL, logged in to the website, and began to register information.

Similar to the previous process of applying for a US visa, there is also a lot of information to be filled in, including passport information, visa information, personal information, contacts in the beautiful country, security issues, and so on.

But this time it is not as cumbersome as last time, you only need to fill in seven pages of information.

After filling, click Submit and wait for review.

During the filling process, Xu Qiu also learned that EVUS was implemented on November 29, 2016, and florists who hold a 10-year US visa are required to register.

It is said that it is a bilateral reciprocal arrangement between the flower planter and the beautiful country, which will help to speed up the entry of domestic tourists to the beautiful country.

Every time the information is updated on the EVUS website, it can be kept valid for two years. Within the valid period, there is no need to update the information when you go to the beautiful country again.

Those who hold visas with other validity periods are not forced to update their personal information.

But it's better to register as well, for example, Tian Qing's five-year visa was also registered before.

After all, one more thing is worse than one less thing. If you are checked when you go through customs because you don’t have registration information, and you can’t speak the language and can’t communicate, it will be embarrassing.

After dealing with the EVUS matter, Xu Qiu approached Wu Feifei and asked, "Who are the experts coming to the meeting this time?"

Wu Feifei pointed to the computer screen: "Here, see for yourself."

Xu Qiu looked at her computer screen, and there was an open WORD file, on which was the meeting schedule, which was still empty, and below was the list of experts who would give reports at the meeting.

There are a total of eight experts on the list, most of which are familiar names.

Including Gong Yuanjiang from Kainan University, Lu Changjun from Chinese Academy of Sciences, Zheng Xiao from Sichuan University, Bao Yuanyou from Jinghang University, and Feng Shengdong who flew over from Lund University in Sweden.

There is also Liang Haoxian, the small boss of Xu Zhenghong's research group and the developer of IDTBR materials.

Xu Zhenghong did not come to this meeting. After all, he was really old, and he had basically retreated to the second line. He would not appear in person on most occasions, but sent Liang Haoxian to appear.

The last time Xu Zhenghong went to the meeting held by Gong Yuanjiang, it may be because they have a good personal relationship.

The friendship between Wei Xingsi and Xu Zhenghong is relatively weak. After all, Teacher Wei has just returned to China not long ago, and Gong Yuanjiang has been operating in China for many years.

In addition, there is an interesting name, Ma Weiwei.

Ma Weiwei was the only female scientist at this conference, and she was also an old acquaintance of Teacher Wei. I don't know if she was invited by Teacher Wei on his own initiative.

In the end, it was Xu Qiu. This time Wei Xingsi did not write his own name, but wrote Xu Qiu's name and sent it to Wu Feifei.

Xu Qiu was also the only speaker at this conference who did not have a professional title. The rest of the speakers were all professors, and many of them were at the level of "Jieqing" and "Yangtze River".

The schedule of the meeting is similar to the meeting organized by Gong Yuanjiang last time:

On Sunday, some people who have a good relationship with Mr. Wei, such as Gong Yuanjiang and Feng Shengdong, will come early.

On Monday, it is mainly for everyone to go around the campus, go around, visit the laboratories, and chat in private.

On Tuesday, the conference officially started. There were a total of eight experts who reported. Xu Qiu asked Wu Feifei to arrange him as the second in the morning, Gong Yuanjiang as the first in the morning, and Feng Shengdong as the fourth in the morning.

The order of others is not too important, Wu Feifei arranges directly according to the way of ROLL points.

30 minutes for each person to report, 15 minutes for questions, four sessions in the morning, starting at 9:00 and ending at 12:00, and four sessions in the afternoon, starting at 2:00 and ending at 5:00, from 9 to 5, the time is relatively tight of.

After negotiating the meeting arrangements with Wu Feifei, Xu Qiu continued to improve his PPT. The skeleton had been built before, but now he still needs to fill in the content.

After working all afternoon, at night, Xu Qiu finally finished the ppt of the conference.

He asked Tian Qing for a template, decorated the PPT, and then took the PPT to Wei Xingsi to discuss and revise.

After reading it, Wei Xingsi only changed some formatting issues, and expressed his satisfaction with the content.

Including Xu Qiu's plan to disclose their IDIC-4F work on "Nature·Energy" at the conference, Wei Xingsi did not raise any objections.

The main reason is that this "Natural Energy" is basically stable. Even if others hear their reports during this period of time, it will be difficult for others to take this job away.

In addition, Wei Xingsi also had the same considerations as Xu Qiu, that is, as the host, there must always be some work that can be offered.

Although there is a "Joule", but it is a review article after all, the weight is not heavy enough, and a system with an efficiency exceeding 13% will be even more shocking.

After finishing the PPT of the conference, Xu Qiu did not continue to prepare the speech, but planned to play it on the spot.

These articles were published through his hands, so it is unlikely that they will not be published at that time.

Xu Qiu didn't plan to continue the experiment this week. Last week, he used too much force and needed to slow down.

However, the simulation laboratory is still running as usual, based on the directions he envisioned at the group meeting.

Although no experiment is done, paddling is impossible.

During this period of time, some other things have accumulated, and Xu Qiu needs to deal with them one by one.

On Tuesday morning, Xu Qiu sorted out the fund summary reports written by others in the organic photovoltaic team, in order to get the final version that can be submitted.

This job is not difficult to do. Just when I made the PPT of the conference on Monday, I sorted out the story line of the ITIC series.

Now Xu Qiu's perspective is very clear, just like a jigsaw puzzle, putting the assigned work in the assigned position, occasionally correcting a few mistakes in expressions, repeating words, and adding a few sentences.

In the afternoon and evening, Xu Qiu began to summarize this year's work, after all, it was the end of the year.

Same as last year's work summary, the English version, organizing each published article into a PPT is not difficult, but it is a little trivial.

On Wednesday, Xu Qiu helped revise the fund book, including the key projects on Wei Xingsi's side, and the outstanding youth fund on Wu Shengnan's side.

The submitted articles are reviewed by reviewers. As long as the work is not too bad, there is a chance to accept it after revision.

There is also a "reviewer" in this book, but because the competition among research groups for project funds is very fierce, especially for books such as key projects and outstanding youth funds, poor writing will be directly ignored, and almost no revisions will be made. Opportunities must be polished very well.

On Thursday, while Xu Qiu was in class, he took the time to read the recently published literature.

In general, the popularity of the organic photovoltaic field has not diminished recently.

Among them, one of the more interesting works was published on AEM, and the corresponding author is Ma Weiwei.

The materials they used were two non-fullerene acceptor materials, ITIC and IEICO. The main highlight was the non-halogen solvent, which also took into account the stability test of the non-fullerene system.

They pointed out in the introduction: "At present, the preparation of high-efficiency organic solar cells generally uses halogenated aromatic hydrocarbon solvents, such as chloroform, chlorobenzene, dichlorobenzene, etc. , will bring great harm to the health of researchers.

Moreover, these solvents are directly discharged into the atmosphere, which will also cause pollution and harm to the environment.

The cost price of these solvents is also high from the standpoint of production cost. These unfavorable factors limit the large-scale production and industrial application of halogenated solvents in the preparation of organic solar cells, and run counter to the purpose of current green chemistry.

Therefore, starting from health and environmental protection, it is imminent to develop low-toxic or even non-toxic non-halogenated aromatic solvents to prepare organic solar cells, and it is also the only way for organic solar cells to be commercialized. "

At first glance, what he said is quite reasonable, and the righteousness is awe-inspiring.

Then, Xu Qiu looked at the solvent used in the article.

I thought there would be some surprises, but it turned out that they used toluene...

Changing chlorobenzene to toluene always feels a bit of a joke.

After all, the harm of toluene is not small...

But at least it is a first step, remove the chlorine first, and then consider whether it can be replaced with a greener solvent.

In the supporting information of this article, they mentioned Blue River Photoelectric Material Company, saying that ITIC, IEICO and other materials were purchased from here.

Speaking of this, when Xu Qiu bought optoelectronic materials before, he originally planned to choose Blue River Optoelectronic Materials Company, but Wei Xingsi stopped him later, saying: "We have participated in Blue River Optoelectronic Materials Company, and doing so may be risky."

Xu Qiu thought about it carefully, and found that it was true, and some of the scientific research funds he spent brought benefits to himself.

Although they are definitely not greedy for money, if someone really compares the truth, it is not easy to explain.

The squeegee coating equipment I bought was not a big problem, because Blue River's main company did not have a shareholding.

It's no wonder that Wei Xingsi chose to invest in Blue River's company in a low-key manner.

It is said that some colleges and universities do not allow professors to open companies in private, but there is no such regulation in Shanghai University, probably because they are afraid that outstanding professors will leave together?

After all, the salaries of college professors are not high, and many bigwigs from the School of Economics have assets in the hands of over 100 million yuan.
