I Have a Research Support System

While Xu Qiu was writing the review proposal, he also helped Chen Wanqing revise her article and added the missing abstract.

The senior sister's article was selected for AELM as she wished.

Teacher Wei did not intervene in the selection of journals to submit to. Xu Qiu felt that her work could be submitted to better journals. Maybe she was afraid that she would not be selected, so it would be too troublesome to change.

After the work in hand was over, Chen Wan was free and had nothing to do for the time being.

Now there is not much time before the Spring Festival holiday, and it is not appropriate to start a new experimental plan.

So, she asked Teacher Wei for instructions, and then went to help Xu Qiu complete the proposal for the review of non-fullerenes.

For this review, she also held similar ideas to him, trying to find the direction of future research from it.

At this time, although her heart was still wavering, she was still more inclined to challenge herself and publish a big article during her Ph.D.

Xu Qiu naturally had no objection to her joining, one more person would be more helpful.

Besides, he still recognizes the senior sister's strength in reading literature and summarizing theories, and her coming here will definitely be a great help.

As for Han Jiaying, after he helped her get started with her article some time ago, he told her to work it out slowly and come to him when she encountered a problem that she couldn't solve.

The school girl is very well-behaved, most of the time she spends her time studying hard by herself, and rarely comes to him, which saves him a lot of energy.

That's fine, if Xu Qiu intervenes too much, it will be detrimental to her growth, and the final ownership of the article is also a problem.

...

As soon as Teacher Wei finalized the review, Chen Wanqing hurriedly consulted with Xu Qiu:

"Student, how do we divide the work for this review proposal?"

Xu Qiu had already planned in his heart. If two people divide the work ahead of time, write each part separately, and then integrate them at the end, there is a high probability that there will be many differences due to the different writing ideas of the two people. In the end, many places may be different. rewrite.

So, without hesitation, he said: "I will be the chief writer, and then I will assign you a task to write a small part of the text each time. After you finish, I will add the text you wrote to the main text. In this way, no problem will be encountered. It's time to deal with it, what do you think?"

"Hmm..." Chen Wanqing lowered her head and pondered for a while, and said, "My original idea was to divide the work into two parts, and then splicing them together after each part is completed, but your method seems more feasible, it's just a requirement for you. It will be higher, can you handle it?"

"No problem," Xu Qiu said confidently, "I made some preliminary preparations a few days ago, and I have already constructed the general structure of the writing."

"That's good." Chen Wanqing said with a smile, "What is the first task you arranged for me?"

"The introduction part," Xu Qiu pointed to the text in the WORD document on the computer, and said, "I've roughly listed it, mainly including 'the development history of the field of organic photovoltaics', 'the development history of non-fullerene acceptors', 'Advantages and disadvantages of non-fullerene acceptors', 'The main content of this review and the differences with other similar review articles', 'Current problems and future development directions and prospects of non-fullerene acceptors ’.” It was a template he took from reviews written by others and applied it to non-fullerene systems.

After a pause, Xu Qiu continued: "For the time being, I have thought of these five parts. If the senior sister has new ideas in the process of writing, she can add some paragraphs flexibly. If she finds that some parts are not easy to write, she can also How about leaving it empty for now, and we can discuss it together after we finish writing it?"

"Okay, no problem." Chen Wanqing nodded in agreement.

She roughly judged that the writing ideas provided by Xu Qiu in the introduction part belonged to the well-regulated type.

This kind of writing method is more suitable for the two newcomers. If they are big names in the field, it doesn't matter if they write more wildly.

After finalizing the preliminary division of labor, Xu Qiu gave the senior sister a copy of the latest document WORD and PPT edited versions.

The cooperation between the two officially started.

...

After Xu Qiu packaged the introduction part, that is, the first part of the text, to the senior, he was mainly responsible for the latter part.

Although it is a plan, there is no need to describe it in detail, but it is still necessary to explain what each part is about.

The theme of the second part is "classification of materials". Xu Qiu directly used the classification of non-fullerene materials in the previous summary.

A total of four categories, including PDI derivatives, A-D-A category, polymer receptor N2200 category and others.

For each category, further subdivisions are required.

For example, the existing PDI derivatives include side chain modified PDI. The modified positions include in-situ, bay, and nitrogen atom positions. The modified side chains include alkyl, aryl, alkoxy, etc., and PDI Dimers include twisted dimers, bridged dimers, and so on.

After classifying and summarizing all the materials, at the end of the second part, there is also a large table titled "Summary of Photoelectric Properties of Existing Non-Fullerene Systems".

This large table covers the names of donor materials and acceptor materials used in all recently published non-fullerene systems, the short-circuit current density, open-circuit voltage, fill factor, photoelectric conversion efficiency of solar cell devices, and references cited Document number.

The workload of this part is not small, but there is not much technical content. It mainly tests carefulness and patience. The corresponding material names must not be wrongly written, the data must be accurate, and references must not be misquoted or omitted.

...

Three days later, Xu Qiu finished the second part and entered the writing work of the third part, with the theme of "core factors affecting the performance of non-fullerene system devices".

He intends to conduct analysis from three specific directions, including light absorption properties, charge transport and microscopic morphology of thin films.

This is actually an analysis method analogous to the traditional fullerene system. Xu Qiu did not change much, and directly used it.

No way, he still doesn't have the ability to independently propose a set of theories. Directly applying the work ideas of his predecessors is the simplest and most effective method.

Not long after this part started, Chen Wanqing brought the introduction part she had written to find Xu Qiu.

"I basically finished the introduction part, and I added a section about the advantages and disadvantages of fullerene derivatives between the 'development history of organic photovoltaic field' and 'development history of non-fullerene acceptors' It is used for transition." Chen Wan paused, and explained in detail:

"The advantages are well-known, such as excellent electron transport performance, etc., I will briefly mention it, and focus on its disadvantages, including almost no absorption of visible light, single molecular structure, difficult to adjust energy level structure, and heat dissipation under air conditions. Instability and more."

"Well, yes, this is indeed more logical, and the context is more smoothly connected." Xu Qiu agreed: "It is precisely because of a series of problems with fullerenes that we have to develop non-fullerenes."

In fact, people in the field of organic photovoltaics, including Xu Qiu, understand that you have mentioned a lot of shortcomings of fullerene, but its high efficiency covers up all the shortcomings, and most people will not Choose to study the field of non-fullerenes to forcibly challenge the difficult mode.

But now that he's writing a review of non-fullerenes, singing the praises of non-fullerene materials, he has to.

And senior sister's narrative method of avoiding the important and trivial is not uncommon in scientific research papers.

As a simple example, the photoelectric conversion efficiency reported by people in the organic field is the highest value presented by a device.

Why is the highest value reported, because people know that under most fullerene systems, the measured value is difficult to maintain. As the test time is extended, ten minutes, one hour or one day, it will soon gradually attenuation.

Attenuation of 0.5% is considered good, and some devices can even attenuate 1%-3%. The device with the highest efficiency of 8% becomes 5% after continuous illumination. If the efficiency of 5% is reported, even the article may be published stay home.

Relevant studies have shown that the reason for this may be that fullerenes form dimers under light conditions, which destroys the fiber morphology of the original battery device.

It is only rarely mentioned in most non-mechanism research literature, that is, literature that focuses on material design and synthesis.

"Are there any other changes?" Xu Qiu asked.

"There are no changes, and the overall writing is based on your previous thinking, but you need to supplement the 'summary main content'." Chen Wanqing said.

"Okay, leave this part to me." Xu Qiu agreed directly, and then asked: "I am more concerned about the part about Zhan Wang. How did you write it?"

"I haven't written this part yet. I think it can be put at the end. Write the outlook part of the main text first, and then go back and add the introduction part. We can discuss it together at that time." Chen Wanqing said.

"En." Xu Qiu nodded, which was the expected answer.

"Then let's continue to divide the work. In the third part, I will be in charge of the 'light absorption performance' part, and you will be in charge of the two parts of 'charge transport' and 'film microstructure'. How about it?"

"Okay." Chen Wanqing readily agreed.

After being divided in this way, the workload of the two is equal, because she left Xu Qiu a tail in the introduction part.

...

Another three days later, the part that Xu Qiu was responsible for had been completed, but the senior sister hadn't finished yet.

He first entered the fourth part, which is the "Summary and Prospect" part, which includes not only a summary of the main problems in the current field, but also an outlook on key research directions in the future field.

It is relatively easy to raise the current problems, just refer to the papers published by others.

These are common problems. The primary problem in the field of non-fullerenes is low photoelectric conversion efficiency, and the secondary problem is that there are relatively few types of acceptor materials.

The latter is difficult to discuss, and the former can be developed in detail, and further expanded to the problems of too strong crystallinity of PDI derivatives, weak charge transport ability of A-D-A small molecules, poor morphology of N2200 polymer blend film, etc. And it can also echo the content of the third part.

All in all, there is a lot to say.

It's easy to find faults anywhere.

After all, it is the field of scientific research, not the field of industrial application, and there are major problems. Otherwise, if there is any scientific research, this field has long been industrialized and listed to make money.

But how to solve these problems, what is the future development direction of the non-fullerene field, that is, "prospect", that is a difficult problem.

It can even be said that it is the most difficult part to write in the entire review proposal. Other people's work content can be quoted elsewhere, but the author's point of view must be shown here.

In fact, what is put forward in the prospect section is only a solution to the problem, to be precise, it is a solution of conjecture.

Of course, this is also normal.

If you already know how to solve the problem, and you still have to write an outlook, you can do it directly, sort out the experimental data, and publish the paper.

However, you can't write indiscriminately, you still have to be reasonable, otherwise you won't be able to convince picky editors and reviewers.

In the process of writing the proposal, Xu Qiu also overturned his impression of the review articles.

When he was reading other people's reviews before, he felt that the review was just a summary of the recent work of other researchers, and it would be fine to classify it.

In fact, in addition to the summary of other people's work, it is more important to put forward the researcher's personal point of view.

This is not only reflected in the prospect section, but also in the text of the formal review to be written in the future.

For example, two works involving other researchers have similar structures of PDI molecules, one has four substituents at the bay position, and the other has the same four substituents at the in-situ position, but the former has better photoelectric properties .

When he summed up, he could objectively explain the experimental phenomenon, "Under this system, the performance of the substituent at the first position is better", but such a description can only give a passing grade.

Obviously, if there is a conjecture about the cause of this phenomenon, such as "under this system, the in-situ substituents will hinder the charge transport between the donor/acceptor due to high steric hindrance, resulting in a decrease in device performance." It will add a lot of points to the article.

He also understands why review articles, editors usually like to choose to invite big names in a certain field.

Because when the boss writes a review, he can integrate his own views, opinions and objective descriptions to inspire others.

This is also where Xu Qiu's current shortcoming lies. He has been in the industry for less than a year, and after all, he lacks some accumulation.

He is very optimistic about this. The field of scientific research is a long-term front, and it pays attention to accumulation. As long as the direction is right, it will be a blockbuster sooner or later.

As for Wu Feifei's EES review, it is a special case. At that time, the field of perovskite was just emerging, and Mr. Wei was the first group of people who studied perovskite in China.

Although her debut work was published on CM, it has been cited hundreds of times. At that time, she was also considered a leader in the perovskite field. She mentioned a lot of unconstrained concepts in the proposal, and she was able to request a paper. The top issue, EES, is no surprise either.

It's just that her success story is difficult for others to repeat.
