Chapter 187: Summary plan

While Xu Qiu was writing the summary plan, he also helped Chen Wanqing revise her article and added the missing abstract part of the article.
The elder sister's article was as she wished and voted for AELM.
Teacher Wei did not interfere more with the choice of journals. Xu Qiu felt that her job could be better journals. Perhaps she was afraid that she would not be successful, so it would be too troublesome to change.
After the work at hand was over, Chen Wan relaxed and had nothing to do.
There is not much time until the Spring Festival holiday, and it is not appropriate to launch a new experimental plan.
So, she and Teacher Wei asked for instructions, and went to help Xu Qiu complete the plan of non-fullerene review together.
For this review, she also held similar ideas to him, trying to find the direction of future research.
At this time, although her heart was still swaying, she was still more inclined to challenge herself and published a big article during her Ph.D.
Xu Qiu naturally had no objection to her joining, one more person would make a difference.
Moreover, he still recognized the strength of the senior sister in literature and theoretical summary, and her ability to come here must be a big help.
As for Han Jiaying, after he helped her article some time ago, he confessed to her to polish the article slowly, and come to him when he encounters a problem that cannot be solved.
The school girl is very well-behaved. She spends most of her time studying hard by herself, and rarely comes to him, which saves him a lot of energy.
This is also good, if Xu Qiu intervenes too much, it will be detrimental to her growth, and the ultimate ownership of the article is also a problem.
...
As soon as she finalized the review with Teacher Wei, Chen Wanqing was busy discussing with Xu Qiu:
"Brother, this review plan, how do we divide the work?"
Xu Qiu had a plan in mind. If the two people divide their work in advance, write their own parts, and finally integrate them, because the two have different writing ideas, there will probably be many differences. In the end, many places may have to be different. Rewrite.
So he said without hesitation: "I will be the chief writer, and then I will give you a task. Write a small portion of the text each time. After you finish, I will add the text you wrote to the main text. In this case, any problems encountered What do you think of it?"
"Um..." Chen Wanqing lowered her head and groaned, and said: "My original idea was to divide the work into two parts, and then join them after each completion, but your method seems more feasible, but this is what you require. 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 writing structure."
"That's fine." Chen Wanqing smiled: "I don't know what is the first task arranged for me?"
"Introduction," Xu Qiu pointed to the text in the WORD file on the computer, and said: "I have roughly listed them, mainly including the development history of organic photovoltaics, the development history of non-fullerene receptors, 'Pros and cons of non-fullerene receptors','the main content of this review and the differences from other review articles of the same type','current problems with non-fullerene receptors and future development directions and prospects '." This is a template he summed up from reviews written by others, and then applied it to non-fullerene systems.
After a pause, Xu Qiu continued: "I think of these five parts for the time being. If the senior sister has new ideas in the process of writing, she can also add some paragraphs flexibly. If you find that some parts are not easy to write, you can also You can leave it empty and we will discuss it together after we finish writing, how about?"
"Okay, no problem." Chen Wanqing nodded in agreement.
She roughly judged that the writing ideas provided by Xu Qiu in the introductory part belonged to the proper type.
This kind of writing method is more suitable for the two of them. If you are a big man in the field, it doesn't matter if you write in a wild style.
After finalizing the preliminary division of labor, Xu Qiu copied the latest document WORD and PPT to the senior sister.
The cooperation between the two officially began.
...
After Xu Qiu packaged the introduction part, which is the first part of the text, to the senior sister, he was mainly responsible for the latter part.
Although it is a plan, there is no need to describe it in detail, but it should be clear what each part is about.
The theme of the second part is "Material Classification". Xu Qiu directly used the classification of non-fullerene materials in the previous summary.
There are four broad categories, including PDI derivatives, A-D-A, polymer receptor N2200 and others.
For each category, further breakdown is needed.
For example, the existing PDI derivatives include side chain modified PDI. The modified positions include in-situ, bay position, and nitrogen position. The modified side chain includes alkyl, aryl, alkoxy, etc., and also includes PDI Dimers include twisted dimers, bridged dimers, and so on.
After all the materials are classified and summarized, at the end of the second part, there is a large table called "Summary of the Optoelectronic 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 Literature number.
The workload of this part is not small, but it does not have too much technical content. The main test is carefulness and patience. The names of the corresponding materials must not be written incorrectly, the data must be accurate, and the references must not be cited or omitted.
...
Three days later, Xu Qiu completed the second part and entered the third part of the writing work, with the topic "Core Factors Affecting the Performance of Non-Fullerene System Devices".
He intends to analyze from three specific directions, including light absorption properties, charge transport, and film microscopic morphology.
This is actually an analysis method that is analogous to the traditional fullerene system. Xu Qiu didn't change it much and used it directly.
No way, he still doesn't have the ability to independently propose a set of theories. It is the simplest and most effective method to directly apply the work ideas of the predecessors.
Not long after this part started, Chen Wanqing brought her written introduction to see Xu Qiu.
"I have basically written the introduction. I added an introduction about the advantages and disadvantages of fullerene derivatives between the development history of organic photovoltaics and the development history of non-fullerene receptors. Used for transition." Chen Wanqing paused and explained in detail:
"Because of the well-known advantages, such as the excellent electron transport performance, I have briefly touched on its shortcomings, including almost no absorption of visible light, single molecular structure, difficulty in adjusting the energy level structure, and heat under air conditions. Instability and so on."
"Well, yes, this is indeed more logical, and the contextual connection is smoother." 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. You said a bunch of fullerenes' shortcomings, but it has the advantage of high efficiency, so all the shortcomings are covered up. Most people will not Choose to study the field of non-fullerenes to forcefully challenge the difficult mode.
But now he is writing a review of non-fullerenes, to sing praises to non-fullerene materials, and he must write like this.
And this kind of narrative method of eschewing the most important is not uncommon in scientific research papers.
A simplest example, the photoelectric conversion efficiency reported by people in the organic field is the highest value presented by a device.
Why report the highest value, because people know that under most fullerene systems, the measured value is difficult to maintain. As the test time increases, ten minutes, one hour or one day, it will gradually gradually attenuation.
An attenuation of 0.5% is considered good. Some devices can even attenuate 1% to 3%. The device with the highest efficiency of 8% becomes 5% after continuous light. If this is reported as an efficiency of 5%, even the article may be published. stay home.
Relevant studies have shown that such a reason may be caused by the formation of dimers of fullerene under light conditions, which destroys the fiber morphology of the original battery device.
This is only rarely mentioned in most non-mechanical research literature, that is, literature that focuses on material design and synthesis.
"Any other changes?" Xu Qiu asked.
"There is no change. I wrote it according to your previous thoughts. However, you need to supplement the main content of the review." Chen Wanqing said.
"Okay, leave this part to me." Xu Qiu agreed directly, and then asked: "I am more concerned about the outlook part, how did you write it?"
"I haven't written this part yet. I think I can put it at the end. Write the outlook part of the main text first, and then come back to add the introduction part. Then we can discuss it together." Chen Wanqing said.
"Yeah." Xu Qiu nodded, this was an expected answer.
"Then let's continue to divide the work. In the third part, I will be responsible for the'light absorption performance' part, and you will be responsible for the'charge transport' and the'film microscopic morphology'. How about?"
"Okay." Chen Wanqing readily agreed.
In this way, the workload of the two is equal, because in the introduction, she also left a tail for Xu Qiu.
...
Three days later, the part Xu Qiu was responsible for had been completed, but the senior sister had not yet completed it.
He first enters the fourth part, 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 current problems, just refer directly to the papers published by other people.
These are all commonplace issues. The primary problem in the non-fullerene field is the low photoelectric conversion efficiency, and the secondary problem is the relatively small number of acceptor materials.
The latter is difficult to discuss, and the former can be further expanded to include the excessive crystallinity of PDI derivatives, the weak charge transport ability of ADA small molecules, and the poor morphology of the N2200 polymer system blend film. And it can also echo the content of the third part.
In short, there is a lot to say.
It's easy to find faults everywhere.
After all, it is the field of scientific research, not the field of industrial application, and there are major problems. Otherwise, what scientific research is still going on, this field has long been industrialized and listed.
But how to solve these problems, what is the future development direction of the non-fullerene field, that is, "looking forward", that is a difficult problem.
It can even be said to be the most difficult place to write in the entire summary plan. Other places can quote other people's work, but the author's point of view must be highlighted here.
In fact, what is put forward in the outlook section is only a solution to the problem, to be precise, it is a solution to a conjecture.
Of course, this is also normal.
If you already know how to solve the problem and write some prospects, you can do it directly, organize the experimental data, and publish the paper.
However, it must not be scribbled, and it must be reasonable, otherwise the picky editors and reviewers cannot be convinced.
In the process of writing the plan, Xu Qiu also subverted his impression of review articles.
When he looked at other people's reviews before, he felt that they were reviews, but it was just a summary of the recent work of other researchers and sorted them.
In fact, in addition to summarizing the work of others, it is more important to put forward the researcher's personal views.
This is not only reflected in the outlook part, but also in the body part of the formal review to be written in the future.
For example, two papers related to the work of other researchers, the structure of the PDI molecule is similar, one has four substituents in the bay position, and the other has the same four substituents in the in-situ, but the former has better photoelectric properties .
When he summarized, he could objectively explain the experimental phenomenon, "Under this system, the performance of the substituent position in the bay position is better", but such a description can only give a passing score.
Obviously, if you match a conjecture about the reason for 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, UU reading www.uukanshu.com. Resulting in reduced device performance" will give the article a lot of points.
He also understands why to review articles, editors usually like to choose experts in a certain field.
Because when writing a review, a big man can blend his own views and opinions with objective descriptions to inspire others.
This is where Xu Qiu's current weakness lies. He has been in the industry for less than a year, and after all, he lacks some accumulation.
He is very keen on this. The field of scientific research is a long-term front. It pays attention to accumulation and development. As long as the direction is correct, sooner or later, it will be a blockbuster.
As for Wu Feifei's EES review, it is a special case. At that time, the field of perovskite was just emerging. Teacher Wei was the first group of people to study perovskite in China.
Although her debut work was published on CM, it has been cited in hundreds of times. At that time, she was considered a leader in the perovskite field. In the plan, she mentioned a lot of wild concepts, and was able to get a piece of material. The top issue EES is not surprising either.
It's just that her success story is difficult for others to repeat.
