I Have a Research Support System

I need to report this matter to Teacher Wei, Chen Wanqing said.

The efficiency is only increased from 4.5% to 5%. Is it so important? Xu Qiu was puzzled.

Well... for the benchmark system of P3HT, 5% is a threshold, Chen Wanqing explained:

Like the article I'm writing now, it's actually not very innovative, and the grade is almost between the second and third SCI districts, but if I have 5% efficiency, then submit to a journal in the second district, and the reviewers will see it. If the efficiency is high, there is a greater chance of passing.

There is no other way to do this. There are too few measurement indicators in the field of optoelectronics. Apart from photoelectric conversion efficiency, there is no other reliable comparison method.

And except for industry leaders, most researchers are pouring water, so how to distinguish the quality of their work, comparing the level of efficiency is a simple method.

Of course, if there are any unique viewpoints and conclusions in the article, it will not be within the scope of the discussion.

Now there are a lot of scientific research workers, and if you want to graduate with a master's or doctoral degree, you must publish articles.

But most people don't have the strength and luck to do groundbreaking work, so they can only pour water.

The end result is that most people do the same routines, so when you have read a certain amount of literature in the same field, you can quickly read a lot of literature.

You just need to see what the story told by others looks like, and be careful not to repeat it exactly with him.

Well, there are so many unspoken rules in the academic circle. Xu Qiu said.

Hmm, doing scientific research is a bit like a card game.

There are SSR, SR, R, N and other cards in the card pool.

For most researchers, the probability of getting N card is more than 90%, and the probability of getting R card is less than 10%. As for SR and SSR, the probability is so low that it can be ignored.

The point is, you don't spend months to years doing experiments without knowing what cards you've drawn.

For the bosses, relying on their unique understanding of the industry, the probability of getting an SSR may reach 1%, but it is still too low.

Then, they will find other people to help them realize their ideas.

This is also the model of a large research group. One academician will lead several Changjiang students, one Yangtze River will lead several outstanding youths, one outstanding youth will lead several Ph. Chen Wanqing said.

It sounds like the model of large research groups is better, so why do most of our schools have small research groups? Why don't we form groups? Xu Qiu asked.

This has something to do with the school. Those who can enter our comprehensive university in Shanghai are all people who have achieved something in a certain field. Such people are often unwilling to be inferior to others easily.

There will be a difference between primary and secondary when merging into a large research group, so most of them do it alone, and at most find other people to cooperate, and they will not easily merge into a large research group.

But for the slightly inferior universities, they are not attractive enough for outstanding scientific research talents.

They may use a building or a large amount of scientific research funds to empty the resources of the entire department, poach an academician and the Yangtze River, and then form a large research group to work together to publicize a direction.

…………

The two came to Teacher Wei's office.

What's the matter, what's the matter? Wei Xingsi was a little surprised when he saw the two of them coming in at the same time.

It's like this. Xu Qiu discovered a new spin coating method. Now the efficiency of the P3HT:PC[60]BM benchmark system has reached 5%, and there is still room for further improvement. Chen Wanqing said cautiously.

Yes, this is a major breakthrough, Wei Xingsi said in admiration, Xu Qiu, tell me how to do the spin coating.

It's just to let the homogenizer rotate first, and then use the pipette gun to quickly spray the solution onto the substrate. Xu Qiu said.

Well, is the repeatability good? Wei Xingsi asked.

It's not bad. I made three pieces, all of which are higher than the ordinary spin coating method. Xu Qiu said.

Wei Xingsi nodded, then stood up, paced in the room while thinking, and suddenly said:

Chen Wanqing, according to Xu Qiu's method, try your current six systems and see if you can improve the efficiency a little bit, for example, by 6%.

When Chen Wanqing heard 6%, she stayed where she was, not daring to answer.

Wei Xingsi ignored her and continued:

Xu Qiu, you've been helping her with the experiment recently, and when the time comes, her article will be a second one for you.

Mr. Wei, I will enter the exam month next week, so I don't think I have much time to do experiments. Xu Qiu said.

Oh, I forgot, Wei Xingsi said, Then let's do this, teach Chen Wanqing the method in the past two days, and let her do it.

Okay, Teacher Wei. Xu Qiu said.

Okay, you guys go get busy. Wei Xingsi took out two boxes of drinks from the refrigerator and handed them to them.

…………

Back in Lab 216, Chen Wanqing couldn't help complaining: 6%, this is more than the world record, he really dares to think about it.

I also think it is impossible. Why do we use the P3HT benchmark system? Xu Qiu said: I see that the PTB7-TH used in the latest published papers can reach a maximum efficiency of more than 10%.

P3HT has been used for more than ten years, and it is the most widely studied. It is usually used by new researchers to practice various experimental operations. Chen Wanqing said:

Its molecular structure is simple, its scientific name is poly-3-hexylthiophene, and its cost is low. If it can be used to make stable and efficient battery devices, it is hopeful to realize industrialization.

After this article is published, I will also do research related to PTB7-TH. Our research group just spent 7,000 yuan in scientific research funds and bought 500 mg of PTB7-TH. After the laboratory is built, it will design its own synthetic materials.

I see, Xu Qiu jokingly said, Mr. Wei was worried about you wasting your research funds, so he asked you to use the cheap P3HT first.

What nonsense are you talking about? Chen Wanqing punched Xu Qiu after she finished speaking.

While the two were laughing, the sound of da da da leather shoes came from the corridor.

Chen Wanqing quickly pretended to be discussing the issue with Xu Qiu:

Approximately how far is that pipette tip from the substrate?

What? Xu Qiu realized when he saw Mr. Wei walking in, and replied:

The position of the pipette tip is about five or six centimeters away from the substrate. It can be closer, but it can't be too far anyway.

Wei Xingsi glanced at the two of them and said, Where is Tian Qing, are you going back first?

Yeah, she just left not long ago. Chen Wanqing said.

Okay, I have something to go back earlier today, Wei Xingsi said, By the way, that one came here to start a project before, but then he ran away. Chen Wanqing, do you have the project information?

Yes, he copied all the project materials to me before he left. Chen Wanqing said.

Xu Qiu, this is a small school project. It's not difficult. It will be finished in November this year. You can take over, do experiments, and make a final report. The project for undergraduates is very simple. Wei Xing thought.

Okay, no problem. Xu Qiu thought for a while and nodded.

Then I'll leave first. When you leave, close the doors and windows. Wei Xingsi said.
