I Have a Research Support System

On Wednesday morning, after sending Han Jiaying to the school bus, Xu Qiu came to Caiyi 216 more than 20 minutes early.

Taking advantage of no one in the laboratory, he entered the spin-coating glove box and began to prepare the solution of the effective layer.

The lab friends came one after another.

Sun Wo was the first one to come besides Xu Qiu, almost ten minutes earlier. After entering the door, he took the initiative to say hello to Xu Qiu, then sat at his desk, took out a few documents from his schoolbag, and read them.

Wu Feifei, Duan Yun, and Tian Qing were still the same, showing up at half past nine, and Tian Qing was two or three minutes late.

The two even-numbered rooms 216 and 218 are adjacent to each other. From whether the lights in 218 are on, we can roughly infer whether Mr. Wei has come.

Seeing that the lights in Teacher Wei's office were dimmed, Duan Yun and the others had no intention of starting the experiment, and sat chatting on chairs.

Even Sun Wo put down his literature and joined the paddling army.

After a while, Wei Xingsi's unique BGM sounded in the corridor.

Everyone got into the mood one after another, Tian Qing began to read the literature, Duan Yun picked up a lab coat and put it on himself, and Sun Wo and Wu Feifei discussed "tin-based perovskite".

Teacher Wei stood at the door of 216, glanced around, saw Xu Qiu who was doing an experiment, his eyes lit up, and he walked over.

I haven't seen him for two days. Teacher Wei seemed to miss Xu Qiu very much. He patted him on the shoulder and said, "Come and see me in the office when you have time."

"Okay." Xu Qiu agreed casually.

Teacher Wei didn't say anything more, turned his head and poked the control panel of the glove box with his finger, the panel canceled the screen saver, and showed the data of water value and oxygen value, both of which were less than 0.1ppm, and 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 kind of consumables, the color of the remaining zinc oxide prepolymer solution from last time has turned yellow like the first bubble in the morning...

Apparently it doesn't work anymore.

It is obviously not important for Mr. Wei to find him, otherwise Mr. Wei would have said it face to face with his character.

Therefore, Xu Qiu was not in a hurry. After preparing the solution, he left the glove box. He walked to the ultrasonic cleaner and cleaned some ITO substrates. Then he took off his lab coat and walked towards 218.

'Since Han Jiaying came, it seems that I haven't cleaned the substrate myself for a long time. '

'On the Nth day when the school girl is away, I miss her. '

...

Room 218.

"Come on, I've submitted the cover of the article to the editor," Wei Xingsi said with a smile on his face, "How is Zhang Jianghege doing?"

"It's okay." Xu Qiu was noncommittal, and now he is going to report to Mr. Wei that he is used to keeping 100 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. On the one hand, this is indeed a rumor in the circle, on the other hand, it is also His habit is to make students work harder by putting appropriate pressure on them.

"What about the molecular structure, didn't you collide with us?" Xu Qiu asked subconsciously. He had already seen Teacher Wei's PY ability, so he didn't doubt the authenticity of the news at all.

"You can't find out such specific details." Teacher Wei shook his head.

"That's true." Xu Qiu thought for a second, this kind of work belongs to the core of other people's work, and no one will disclose it casually. At most, they can reveal a general direction.

"Based on your current system, how much room for further improvement do you expect? It's really not possible..." Wei Xingsi paused and said:

"Just achieve 5% of the molecular structure before you die, try to see if you can optimize the device to 6%, and then submit an article to CM or Wiley's new journal Adv. Sci."

CM is an ordinary journal in the first district, with an impact factor of around 10. Wu Feifei published an article before, and Wiley’s new journal Adv. The advantage is that there is a lack of manuscripts and it is easy to get in, but it is embarrassing for the students. After the division is released, everyone may graduate.

"Hmm..." Xu Qiu thought deeply, "Teacher Wei doesn't know that I have optimized the efficiency to 6% now, which is an important watershed, and the first district is basically stable." '

'And his perspective is different from mine. According to the normal situation, the independent design and synthesis of a new PDI system is carried out in a cycle of molecular structure optimization and device optimization. The time for each iteration will not be short, and it may take one month each time. , if multiple iterations are required, the synthesis time scale will be very long, even more than half a year is possible. '

‘Now there are two clear competitors and several unknown competitors. In addition, my molecular structure is relatively simple, so there is a possibility of colliding with others. This is Teacher Wei’s main concern. '

'Comparatively speaking, the structure of the two molecules of the school girl is more complicated in design, so there is no need to worry about the risk of crashing. '

‘However, 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, so there is room for escape. '

'And the existence of a system can greatly shorten the time of trial and error, and 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 better articles in the first area. '

‘However, we need the help of our juniors to catch up with the progress, so let’s play it safe…’

Thinking of this, Xu Qiu pondered for a while and said, "Give me another month, I am confident that the efficiency will reach more than 6%, and I will spend another month supplementing the data and writing articles."

"Okay, okay." Wei Xingsi nodded in satisfaction. According to previous observations, every time Xu Qiu said this, there was a high probability of success, "By the way, I have already bought the dedicated computer for TRPL and put it in the utility room. Install the software when you have time, and ask Qiu Heming for the permanent activation code."

"Okay, I'll contact him later." Xu Qiuying agreed.

"There is also a microwave reactor. I have already contacted the manufacturer. They should come to install it next week. At that time, Zhang Jiang will need someone to respond." After a pause, Wei Xingsi continued: "How is the review going?"

"The third part of the review will be finished soon," Xu Qiu recalled the previous PY incident, and asked, "When shall I discuss it with Teacher Tang?"

"I'll contact Tang Yunkun later," Wei Xing thought for a while and said, "Tentatively decide tomorrow, you'll be in Handan tomorrow."

"Here I am."

"Okay, you go to work first."

After a delay in Mr. Wei's office, the glove box has been occupied by Sun Wo, and Wu Feifei is instructing him to spin-coat the effective layer of perovskite.

Xu Qiu was not in a hurry. He first went to the ultrasonic cleaner to replace the cleaning solution with acetone, then contacted Qiu Heming on WeChat to ask for an activation code, copied the installation package of the TRPL software from his computer, returned to 218, and gave it to the new The software was installed on the computer, activated successfully, tested, and there was no problem, and finally got the news from Teacher Wei that "discuss with Tang Yunkun at 2 o'clock tomorrow afternoon".

Back at 216, because the seniors and the juniors were not there, Xu Qiu sat next to Tian Qing, had a few polite words with her, chatted about the cover of the article, and learned that Teacher Wei gave her an extra 200 yuan for the workbook fee.

Speaking of which, Tian Qing has never gone to Zhangjiang to synthesize perovskite quantum dots since she broke him and Han Jiaying last Monday.

Based on her performance during the group meeting, Xu Qiu roughly guessed the reason. She didn't really want to get involved with chemical experiments.

Teacher Wei didn't seem to care about it. I don't know if the two of them have negotiated.

But Xu Qiu didn't think much about it, as none of this had much to do with him.

...

In the afternoon, Xu Qiu prepared a batch of devices based on three kinds of 3D-DPI molecules, namely his third-generation 5 series, and Han Jiaying's first-generation B3T and B4T series.

This time he did not intentionally compress the efficiency as before, but directly took the optimal results of the simulation laboratory II as the starting point - the donor materials were all P3TEA, the solvent was chloroform, DIO solvent additive was used, etc...

Based on this condition, further optimization is carried out, such as adjusting the speed, the addition ratio of DIO, and so on.

On the one hand, it is because the senior sister and the junior sister are not in Handan, and no one pays attention to his experimental results in real time. It is completely possible to report a lower value after measuring a high value.

On the other hand, he still has three generations of 6/8 series on the way. The system of the school girl can also develop the second and third generations. There is room for a substantial improvement in device efficiency. It is not the final generation of products, and there is no need to hide them. tucked in.

In the final result, the optoelectronic performance of these devices, except for 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 were 6.22%, 4.17% and 4.38%, respectively, and the previous values ​​were 5.98%, 4.08% and 4.87%.

Xu Qiu is not surprised that the device performance of the first-generation B4T series has decreased, because DIO was added before spin coating. At that time, I accidentally added some more, and there was no time to prepare a new bottle of solution, so I had to bite the bullet and do it down.

Although the performance has been reduced, at least one experimental conclusion has been obtained, "The performance of the 3D-PDI system device is greatly affected by the solvent additive", which can be regarded as a gain.

In addition, during the experiment, Xu Qiu stared at the effective layer film he had spin-coated, and vaguely felt that he had caught something, "Solvent...solvent additive...crystallinity...blend morphology..."

"I understand... a mallet." The inspiration for the experiment seemed to be gushing out, but it stopped abruptly.

He couldn't get up and down, which made him very uncomfortable.

After thinking about it, it is actually quite normal. Many experimental inspirations can only be realized through repeated experiments.

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 of the limitations of the simulation experimenters, they can only conduct simulations based on Xu Qiu's ability.

If his abilities don't improve all the time, the upper limit of simulated experimenters will be fixed forever.
