Chapter 233: Suddenly stopped inspiration

On Wednesday morning, after sending Han Jiaying to the school bus, Xu Qiu arrived at Caiyi 216 more than twenty minutes earlier.
???? With no one in the laboratory, he entered the spin-coating glove box and began to prepare the effective layer of solution.
???? The lab friends came one after another.
???? Sun Wo was the first one outside of Xu Qiu to come. Almost ten minutes in advance, he took the initiative to say hello to Xu Qiu after entering the door, then sat at the desk, took out a few documents from it, and read it. stand up.
???? Wu Feifei, Duan Yun, Tian Qing are still the same, appearing at 9:30, Tian Qing is still two or three minutes late.
???? The two even-numbered rooms of 216 and 218 are adjacent. You can roughly infer whether Teacher Wei has come over by whether the light is on at 218.
I caught a glimpse of the lights in Teacher Wei's office. Duan Yun and the others did not intend to start the experiment. They sat on the chairs and chatted.
???? Even Sun Wo put down the literature and joined the paddling army.
???? After a while, Wei Xingsi's unique BGM sounded in the corridor.
Everyone entered the state one after another. Tian Qing began to read the literature, Duan Yun picked up a lab coat and put it on himself, while Sun Wo and Wu Feifei discussed "tin-based perovskite".
???? Teacher Wei stood at door 216, glanced around, saw Xu Qiu who was doing the experiment, his eyes lit up, and he walked over.
I haven't seen him for two days. Teacher Wei seems to miss Xu Qiu very much. He patted him on the shoulder and said, "Come to the office when you have time to find me."
???? "Okay." Xu Qiu agreed casually.
???? Teacher Wei didn't say anything. He turned his head and poked the control panel of the glove box with his finger. The panel released the screen saver, revealing that the water value and oxygen value were less than that, so he left with satisfaction.
????‘No gloves, bad review. Xu Qiu complained about Mr. Wei's irregular operation and continued to prepare the zinc oxide prepolymer solution.
???? Han Jiaying is not in the Handan laboratory now. No one has prepared this consumable. The color of the remaining zinc oxide prepolymer solution last time has turned yellow like the first bubble in the morning...
???? Obviously it is unusable.
???? Obviously it is not important for Teacher Wei to find him, otherwise he would speak directly to him with his personality.
So Xu Qiu was not in a hurry. He finished preparing the solution and left the glove box. He walked to the ultrasonic cleaner. He cleaned some ITO substrates. Then he took off his lab coat and walked towards 218.
????‘Since Han Jiaying came? I don’t seem to have cleaned the substrate myself for a long time. ’
????‘The Nth day when the school girl is away? Miss her. ’
????......
???? Room 218.
???? "Come on, I have submitted the cover of the article to the editor?" Wei Xingsi hung a smiling face, "How about Zhang Jiangshen's work?"
???? "It's okay." Xu Qiu is noncommittal? Now I'm looking to Teacher Wei to report that he is used to keeping a hundred million hands.
???? "Well? I got some inside information. At least two groups in China are doing 3D-PDI, so we have to hurry up." Teacher Wei said in a deep voice, this is indeed a rumor in the circle? On the other hand, it is also his habit? By giving students appropriate pressure, students can work harder.
???? "The molecular structure, didn't you crash with us?" Xu Qiu asked subconsciously. He had already seen Teacher Wei's PY ability, so he didn't doubt the news at all.
continue reading! Authenticity.
???? "I can't inquire about such specific details." Teacher Wei shook his head.
???? "That's true." Xu Qiu changed his mind to the core of other people's work. No one would disclose it casually. At most, it would reveal a general direction.
???? "Based on your current system, how much room for further improvement do you expect? It really won't work..." Wei Xingsi paused:
???? "Just do the 5% molecular structure before you die, try to optimize the device to 6%? Then vote for a CM or Wiley's new publication Adv.Sci."
???? CM is an ordinary regional journal? The impact factor is about 10? Wu Feifei published an article before, and Wiley’s new journal Adv.Sci. targets AM’s sub-journals AEM and AFM, similar to ACSEnergyLetter. The advantage of the new journal is that it is short of manuscripts and it is easy to get in, but it is more embarrassing for students. When the division comes out, everyone may graduate.
???? "Hmm..." Xu Qiu thoughtfully said, ‘Ms. Wei still doesn’t know that I have optimized the efficiency to 6%. This is an important watershed. The first district is basically stable. ’
????' And he and I have different perspectives. According to normal conditions, we independently design and synthesize a new PDI system, which is carried out in a cycle of molecular structure optimization and device optimization. The time of each iteration will not be short, and it may be necessary every time. In a month, if multiple iterations are required, the time scale of synthesis is very long, and it is possible for more than half a year. ’
????‘Now there are two clear competitors and a number of unknown competitors. In addition, my molecular structure is relatively simple, and there is a possibility of collision with others. This is the main concern of Teacher Wei. ’
????'Relatively speaking, the two molecular structures of the school girl are more complicated in design, so there is no need to worry about the risk of collision. ’
????‘But my structure has been developed for three or four generations, and there is a high probability that other people’s paths will not be exactly the same as mine, and there is still room for it. ’
????’And the existence of a system can greatly shorten the trial and error time, one day can beat others for three or four days. ’
????‘In this way, I should be able to publish the article within a month at the earliest, and the efficiency may reach 7% or more, and I have the opportunity to publish a better section of the article. ’
????‘But you need the help of the school girl to make progress in this way, so let’s be steady...’
???? Thinking of this, Xu Qiu deliberated and said: "Give me another month, I am confident that the efficiency will be above 6%, and spend another month to supplement data and write articles."
???? "Okay, okay." Wei Xingsi nodded in satisfaction. According to previous observations, every time Xu Qiu said this, it is likely to be successful, "By the way, I have bought the special computer for TRPL and put it in. In the utility room, you have time to install the software, and then ask Qiu Heming for a permanent activation code."
???? "Okay, I will contact him later." Xu Qiuying said peacefully.
"There is also a microwave reactor. I have already contacted the manufacturer. They should install it at the door next week. Zhang Jiang will need someone to answer it." After a pause, Wei Xingsi continued: "How about the review? Up?"
???? "The third part of the review will be written right away," Xu Qiu remembered the things about PY before and asked actively: "When should I discuss it with Teacher Tang?"
???? "I will contact Tang Yunkun later," Wei Xing thought for a while and said, "Tentatively, tomorrow, you will be in Handan tomorrow.
continue reading! Right. "
????"I'm here."
???? "Okay, go ahead and work."
There was a delay in Teacher Wei’s office. The glove box was already occupied by Sun Wo, and Feifei Wu was instructing him to spin-coat the effective layer of perovskite.
???? Xu Qiu is not in a hurry, he first went to the ultrasonic cleaner to change the cleaning fluid to acetone, then contacted Qiu Heming via WeChat to ask for the group activation code, copied the TRPL software installation package from his computer, and returned. 218. Installed the software on the new computer, activated it successfully, tested it, no problem, and finally got the message of "discuss with Tang Yunkun at two o'clock tomorrow afternoon" from Teacher Wei.
???? Back to 216, because the senior sister and the senior sister were not there, Xu Qiu sat next to Tian Qing, and chatted with her a few words about the cover of the article, and learned that Teacher Wei gave her extra 200 yuan cost.
???? Speaking of, Tian Qing has never gone to Zhangjiang to do the synthesis of perovskite quantum dots since he crashed into him and Han Jiaying last Monday.
???? Combined with her performance during the group meeting, Xu Qiu roughly guessed the reason. She didn't want to be exposed to chemical experiments.
???? Teacher Wei seems to be indifferent, I don't know if the two of them have negotiated.
???? But Xu Qiu didn't think much about it, none of this had much to do with him.
????......
In the afternoon, Xu Qiu prepared a batch of devices based on three 3D-DPI molecules, namely his third-generation 5 series, and Han Jiaying's first-generation B3T and B4T series.
???? This time he did not deliberately compress the efficiency as before, but directly started with the best results of the simulation laboratory II-the donor materials are all P3TEA, the solvent is chloroform, the solvent additives are used, etc...
???? Further optimization based on this condition, such as regulating the speed, the addition ratio and so on.
???? On the one hand, because the school sister and the school girl are not in Handan, no one pays attention to his experimental results in real time. After measuring the high value, it is possible to report a lower value first.
???? On the other hand, he still has three generations of 6/8 series on the road. The school girl system can also develop the second and third generation ~EbookFREE.me~ There is room for significant improvement in device efficiency, not There is no need to hide the final product.
???? The final result, the photoelectric performance of this batch of devices, in addition to the first-generation B4T series, the other two series have improved compared with the results in the simulation laboratory II.
???? Among them, the efficiencies of the third-generation 5 series, the first-generation B3T and B4T series are %,% and% respectively, and the previous values ​​are %,% and% respectively.
????The performance degradation of the first-generation B4T series devices is not unexpected, Xu Qiu, because it was added before spin coating. At that time, a little more was accidentally added. Time was too late to reconstitute a bottle of solution, so I had to bite the bullet. Do it down.
???? Although the performance is reduced, at least one experimental conclusion is obtained, "The performance of the 3D-PDI system device is greatly affected by solvent additives", which can be regarded as a gain.
In addition, during the experiment, Xu Qiu stared at the effective layer film he spin-coated, vaguely feeling what he had caught, "solvent...solvent additive...crystallinity...blending morphology... "
???? "I see... a mallet." The experimental inspiration seemed to gush out, but it stopped abruptly.
???? Not going up and down, making him very uncomfortable.
???? I thought about it, it's actually normal, and many experiment inspirations have to be repeated
continue reading! It can be realized in the experiment.
???? Recently, he has relied too much on the simulation laboratory, and the frequency of practical operations other than organic synthesis has dropped significantly.
???? This is not a good thing, because the limitations of the simulation experimenter can only simulate based on Xu Qiu's ability.
???? If his ability does not improve, the upper limit of the simulation experimenter is always fixed.
