Chapter 30: Take over the project

　　 "This matter should be reported to Teacher Wei." Chen Wanqing said.
　　 "The efficiency is only increased from 4.5% to 5%, is it so important?" Xu Qiu 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. The grade is almost between the second and third SCI regions, but if I have 5% efficiency, then I will submit it to the second-region journal and the reviewers will look at it. When the efficiency is quite high, there is a greater chance of passing.
　　 There is no other way. There are too few measurement indicators in the field of optoelectronics, and there is no other reliable method of comparison except for photoelectric conversion efficiency.
　　 In addition to industry leaders, most researchers are irrigating, so how to distinguish between the pros and cons of their work, the level of efficiency is a simple method.
　　 Of course, if there are any unique viewpoints or conclusions in the article, then they will not be discussed.
　　 Nowadays there are a lot of scientific research workers, and if you want to graduate with a master's degree or a doctoral degree, you must post articles.
　　 But most people do not have the strength and luck to complete the groundbreaking work, so they can only irrigate.
　　 The final result is that most people do the same work routines, so when you have reached a certain level of literature reading in the same field, you can quickly read a lot of literature.
　　 Just look at what the story told by others is like, and be careful not to repeat it completely with him. "
　　 "Well, there are so many unspoken rules in academic circles." Xu Qiu said.
　　 "Well, doing research is a bit like a card game.
　　 There are SSR, SR, R, N, etc. cards in the card pool.
　　 For most researchers, the chance of getting an N card is more than 90%, and there is less than 10% chance of getting an R card. As for the higher SR and SSR, the probability is negligible.
　　 The key is that you don’t spend months to years to complete the experiment, and you don’t know what card you got.
　　 For the big guys, with their unique understanding of the industry, the probability of getting 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 brings several Yangtze Rivers, one Yangtze River brings several outstanding young people, one outstanding young people brings several Ph.Ds and post-doctoral fellows, and one post-doctoral post-doctoral fellow brings several undergraduates. "Chen Wanqing said.
　　 "It sounds like the model of a large research group is better, so why are most of our schools small research groups, why don't you hold a group?" Xu Qiu asked.
　　 "This is related to the school. Those who can enter our Magic City University are all people who have achieved achievements in a certain field. Such people are often unwilling to succumb to others easily.
　　 When merged into a large research group, there will be a difference in priority. Therefore, most of them do it alone, and at most find other people to cooperate, rather than easily merge into a large research group.
　　 But for the lesser universities, they are not attractive enough for outstanding research talents.
　　They may use a building or a large amount of research funding to empty out the resources of the entire department, dig an academician, the Yangtze River, and then form a large research team to work together in public relations. "
　　…………
　　 The two came to Teacher Wei's office.
　　 "What's wrong, what's the matter?" Wei Xingsi was a little surprised when they saw the two coming in at the same time.
　　 "That's it. 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 exclaimed, "Xu Qiu, tell me how to spin coating."
　　 "It is to turn the homogenizer first, and then use the pipette gun to quickly spray the solution onto the substrate." Xu Qiu said.
　　 "Well, is the repeatability good?" Wei Xing thought.
　　 "It's okay, I made three pieces, all of which are higher than ordinary spin coating methods." Xu Qiu said.
　　 Wei Xingsi nodded, then stood up, pacing in the room while thinking, suddenly said:
　　 "Chen Wanqing, you follow Xu Qiu's method and try your current six systems to see if you can improve efficiency, such as 6%."
　　 Chen Wanqing heard 6% and stayed where she didn't dare to answer.
　　Wei Xingsi ignored her, and continued:
　　 "Xu Qiu, recently you helped her do experiments together, and then her article will be a second article for you."
　　 "Ms. Wei, I will enter the exam month next week. I don't think there is much time for experimentation." Xu Qiu said.
　　 "Oh, I forgot," Wei Xingsi said, "Well then, you teach Chen Wanqing the method these two days and let her do it."
　　 "Okay, Teacher Wei." Xu Qiu said.
　　 "Okay, you go to work." 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 but vomit: "6%, this is all over the world record, he really dare to think about it."
　　 "I also think it's impossible, so why do we use the P3HT benchmark system?" Xu Qiu said: "I see that the highest efficiency of PTB7-TH used in the latest published paper can reach more than 10%."
　　 "P3HT has been used for more than ten years, and the research is the most extensive. 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 that it can be industrialized.
　　 After this article is published, UU read www. uukānshu. com I will also do research related to PTB7-TH. Our research team just spent 7,000 yuan in research funding and bought 500 mg of PTB7-TH. I will wait until the laboratory on the Zhangjiang campus is completed in the next semester. Design synthetic materials by yourself. "
　　 "I see," Xu Qiu joked, "Ms. Wei is worried that you will waste scientific research funds, so I let you use cheap P3HT first when you get started."
　　 "What nonsense is it?" Chen Wanqing gave Xu Qiu a punch after she finished speaking.
　　 As the two laughed, the sound of leather shoes came from the corridor.
　　 Chen Wanqing quickly pretended to discuss issues with Xu Qiu:
　　 "How far is the pipette tip from the substrate."
　　 "What?" Xu Qiu reacted when she saw Teacher Wei walk 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, go back first?"
　　 "Yeah, she just left." Chen Wanqing said.
　　 "Okay, I have to go back sooner today if I have something to do," Wei Xingsi said, "By the way, who came here to open a project before, and then he ran away. Do you have the project information, Chen Wanqing."
　　 "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 completed in November this year. Come take over, do the experiment, and make a final report. The undergraduate project is very simple." Wei Xing thought.
　　 "Okay, no problem." Xu Qiu thought about it for a while and nodded.
　　 "Then I will go first, and the doors and windows will be closed when you leave." Wei Xing thought.
