Chapter 252: What kind of work efficiency is this?

In the next few days, Xu Qiu prepared a batch of devices on average every day, and also took time to test the data of atomic force microscope AFM and differential scanning calorimeter, and drew the latest light/dark state J-V curve and EQE curve.
　　 Around 4 pm on Thursday, Feifei Wu received a WeChat call from Teacher Wei.
　　 Wei Xingsi said that his exchange report abroad went very smoothly. He returned to the magic city on Friday afternoon and held a group meeting on Sunday, where he would check everyone's work progress.
　　 Everyone in the office got the news and started to take action, and work efficiency increased by 1%-50% on average.
　　 Tian Haru is the 50%. From her look, there is quite a feeling that the vacation is about to end, but the winter homework has not yet begun to write.
　　 And Xu Qiu is naturally the 1%, he is still very calm, because the recent experiments and articles are progressing smoothly.
　　 As for the improvement of work efficiency, it is purely infected by the motivated work state of other people.
　　 After Xu Qiu tested a batch of devices prepared today, he began to count the gains in the past few days:
　　 The third-generation 8 series and the second-generation DI system, in addition to the GIWAXS light source test, other characterization data have been completed, the highest efficiency of the two devices were optimized by him to 8.38% and 7.25%,
　　 Strictly speaking, this is not an optimization, but simply repeats the experiment according to the optimal experimental conditions.
　　 Top journals like NC have very high requirements for data reproducibility. To be less, five batches of devices must be repeated.
　　 For other researchers, repeated experiments are carried out many times, and at the same time, they have the idea of ​​breaking new highs in efficiency. Therefore, many research groups will repeat the preparation of ten or even twenty batches of devices.
　　 Unlike Xu Qiu, he has seen the efficiency boundary based on the two systems in advance in Simulation Lab II-the highest value is 8.42%, which is the result obtained by repeating hundreds of times.
　　 Now only four batches of devices have been made, which can reach 8.38%. Xu Qiu is very satisfied.
　　 Therefore, Xu Qiu is going to follow the minimum standards and evaporate a batch of devices tomorrow, so that five batches of devices can be obtained to meet the minimum requirements.
An average batch of five devices is made, and each has six independent batteries with an area of ​​0.09 square centimeters. Even if there are individual abnormal sample points that need to be discarded, there are more than 20 different battery devices and more than 100 data. Points are available, and the amount of data is not small.
　　 In his free time doing experiments, Xu Qiu is also simultaneously processing experimental data, drawing charts, and writing articles.
Up to now, the experimental description part of the article has been completed, including the GIWAXS test data that has not yet been obtained. Xu Qiu also guessed a general result and wrote it in the article. It will only be verified by going to the Magic City Light Source Test next week. .
　　 He did not guess the result of GIWAXS naturally, but obtained it through reasoning through the correlation between various experimental data.
In the results of DSC, the 3D-PDI molecules did not show obvious crystallization peaks, which means that compared with simple PDI molecules, the crystallinity of 3D-PDI molecules is obviously suppressed; and the image data shows that there is no obvious PDI in the effective layer film. The aggregation phase also supports the conclusion drawn by the DSC results; based on the results, it can be reasonably inferred that there will be no very obvious receptor crystallization signals in the GIWAXS results, otherwise it will be inconsistent.
　　 Of course, since it is an inference or inference, there is also the possibility of problems.
　　 For example, in case the GIWAXS test results are really inconsistent with other characterization methods.
　　 In such a situation, it is possible that a new experimental phenomenon has been discovered, which will overturn some of the existing theoretical frameworks, but this probability... is so small that it can be ignored.
　　 The greater possibility is that there is a problem in the sample preparation, test method, or other places, causing the experimental results to be distorted.
　　 What is the specific reason, it can only be investigated slowly.
　　 In the evening, Chen Wanqing and Han Jiaying took the school bus from Zhangjiang back to Handan campus at 8:30 to Caiyi 216.
　　 After entering the door, the senior sister digs out a garbage bag from her backpack, which contains several glass bottles, and walks towards the inner laboratory with the garbage bag.
　　 Han Jiaying glanced at Wu Feifei, who was wearing headphones and writing a review. Without disturbing her, she walked over to Xu Qiu and sat down.
　　 Apart from Wu Feifei and Xu Qiu in the office, everyone else in the room was doing experiments in the laboratory. Upon seeing this, Han Jiaying couldn't help asking, "What happened to them today?"
　　 School girl glanced at the time, and added: "It's past nine o'clock now."
　　 "Ms. Wei will be back tomorrow afternoon, and a group meeting will be held on Sunday." Xu Qiu briefly explained.
　　 "So that's the case." Han Jiaying understood in seconds. She was not well informed in Zhangjiang. Teacher Wei did not find her and Chen Wanqing this week, and Xu Qiu also reported on the progress of experiments in the organic field.
　　 "What about the product, isn't it finished?" Xu Qiu asked casually when she saw the school girl come back empty-handed.
　　 "It's too early, and the fourth step is only now," Han Jiaying spread her hands, "The molecular synthesis path of the third-generation B4T-5/6/8 series is too long, and the synthesis will definitely not be completed this week."
"That's true." Xu Qiu nodded, and then thought about it. In addition to experimenting, the school girl also worked on exploring microwave reactors and writing articles during this period. In addition, she has to take two classes a week, including one. It is also Zhou Mathematics' "Material Preparation and Processing", the work pressure is really not small.
　　 Thinking of this, Xu Qiu looked at her head with some worry. According to his observation, the school girl's hairline moved backwards by a few tenths of a millimeter.
　　 Such a beautiful girl would not be bald young.
　　 Han Jiaying was seen by Xu Qiu somewhat inexplicably, always feeling that he was thinking about something weird, but there was no evidence.
　　 She paused and asked: "Brother, how is the article written."
　　 "The progress is okay." Xu Qiu was sorting and reviewing the five pictures used in the article on the computer at this time. After all, the pictures are the facade of an article, and there should be no omissions.
The specific method is to directly drag the picture drawn from the software to the PPT for saving, so that if you need to modify the picture in the future, you can directly double-click the picture from the PPT to automatically hyperlink to the related software for modification. The modified result will also be synchronized in the PPT, and then saved as a picture in BMP format. The original picture can be replaced by cutting off the white edges.
　　 Xu Qiu looked at the taskbar at the bottom of the computer screen and found that the WORD draft file of the article was not closed, so he switched to the WORD document directly, sliding the mouse wheel to show the school girl his work progress over the past few days, and at the same time introduced:
　　 "In addition to the light source, the data processing, graphics, and description of the text of the other experimental characterization have been completed, and the introduction is about half written, and the abstract, conclusions, experimental details, references and supporting information are still missing."
　　 "So fast!" Han Jiaying exclaimed. If the article is written to this level, it is considered to be more than half completed.
The school girl recalled her progress. She started writing on this Monday, and she took one week less time than Xu Qiu, but now the total progress of the article is only about 20%. This is still in Xu Qiu’s help. She processed part of the data.
　　 You must know that she hasn't fished in the past few days. She writes articles as long as she is free, and she is conceiving the frame of the article even on the school bus.
　　 I still remember that last Sunday, the senior brother said that this article had a chance to impact AM, and she instantly ignited fighting spirit.
　　 Within a few days, the senior brother told her that she had broken the world record of the PDI system and achieved an efficiency of 8.3%. At that time, she was not surprised, as if it were taken for granted.
　　 Now, after five days, my brother has made five batches of devices, supplemented four or five experiments, almost completed the data, and even wrote half of the article.
　　 What kind of work efficiency is this? Meow meow meow?
　　 She has always wanted to catch up with her brother, but now it seems that the gap is still quite big, she is a cat cat.
　　 Xu Qiu didn't hear the school girl's movement for a while, so he turned his head and looked curiously, and found that the school girl's expression was constantly changing, so he shook his hand in front of her, "What do you want?"
　　 "Ah, nothing..." Han Jiaying quickly changed the subject, "Brother, how can I write articles to get up quickly."
　　 Xu Qiu naturally knows the method. It is nothing more than writing and reading, practice makes perfect, but this is obviously not the answer that the school girl wants to hear.
　　 He thought for a while, gestured with both hands and said, "First...and then...in the end, have you lost your studies?"
　　 "It's a waste, it's a waste." Han Jiaying leaned back in the chair, tilted her head, and made a "broken play" look.
　　 At this time, Chen Wanqing came out of the inner laboratory, looked at the two playing around, and said:
　　 "My CH3 has been synthesized, about 30 mg, and it has been placed in my lock box in the glove box."
　　 "Well," Xu Qiu casually cares: "Senior sister did not encounter any danger when using malononitrile."
"There is no danger, but the reaction was not smooth at the beginning," Chen Wanqing sighed lightly, "I failed twice in the cyano group, but there was no product. The third time was successful. Fortunately, I left some The inventory of aldehyde-based D units, otherwise it is estimated that the final product will not be available this week."
　　 "At least the result is good," Xu Qiu comforted, and said: "I will help you make the device tomorrow."
　　 "Okay," Chen Wanqing said with a smile: "Then I will do some basic characterization tomorrow, and then send samples for nuclear magnetic and elemental analysis."
Xu Qiu suddenly suggested: "Senior sister, do you want to consider changing the name of your molecule? Forget it before. Now it becomes CH. C and H can easily be misunderstood to refer to carbon and hydrogen. It will definitely be inconvenient to put it in the article later."
"I also found this problem," Chen Wanqing stuck out her tongue awkwardly, "I didn't pay attention at the beginning. Now I look at my ~EbookFREE.me~ and it feels like looking at Methyl. In the case of CH4, it becomes methane again..." At the end, the senior sister couldn't help but smile and asked, "Do you have any suggestions?"
　　 "I think it can be named directly with the D and A structural units of the A-D-A molecule," Xu Qiu said of his previous naming method, enumerating: "CH1 can be renamed and renamed IDT-I."
　　 "This is a relatively common naming method in the world." Chen Wanqing nodded, "Actually, I still prefer simple naming, but it is not appropriate to use CH. It is a pity that I am a surname."
　　Senior sister thought for a while, shook her head and said: "I can't think of a better naming method for the time being, so let's name it your way first."
　　 "Yes." Xu Qiu was noncommittal.
　　 At ten o'clock in the evening, the laboratory is still brightly lit, and a few of them still haven't come out.
　　 Sun Wo is testing the device in the vapor deposition glove box, Tian Qing squatting in front of the CELIV instrument and busy, Duan Yun's thermoelectric instrument is also in operation.
　　 Insert a sentence, the book-chasing app I am using recently, cache reading, offline reading!
　　 Sun Wo is a special one. He is so busy now that it is not the reason for paddling, but because he gave Xu Qiu the glove box.
　　 Xu Qiu walked into the laboratory and greeted them with a smile, and copied the IDT-I product of the school sister to the simulation laboratory II, and handed it over to the simulation experimenter for device performance exploration.
　　 Then, he and his school sister returned to the dormitory.
