I Have a Research Support System

After chatting with Xu Qiu about the work of the PDI system for a while, Wei Xingsi suddenly asked, "How are Chen Wanqing and Han Jiaying doing? I haven't seen them much these days."

"Oh, the two of them are doing synthesis in Zhangjiang," Xu Qiu chatted with the schoolgirls every day and knew their current situation very well, so he replied for them:

"Han Jiaying is working on 3D-PDI materials. Before that, she only obtained tens of milligrams of the product, but now she is preparing it in large quantities. Chen Wanqing has obtained the raw material of 1,3-indenedione, and is synthesizing a newly designed A-D-A molecule, CH1."

Wei Xingsi nodded noncommittally, and suddenly said: "Speaking of synthesis, the microwave reactor contacted me today, and their engineer happened to be in Shanghai recently, and asked us if we could install it this Thursday or Friday. The time is awkward, It just happened that after I went abroad, someone had to check and accept it when installing the equipment, are you free these two days, if not, I will reject it first, and make an appointment when I come back."

'The school girl's current system may require a microwave reactor. If it is not installed this time, I don't know how long it will be delayed. After all, their engineers have traveled all over the country and will not stay in the magic city all the time. , if it is just acceptance, there should be no problem. '

After thinking for a while, Xu Qiu took the matter aside: "I'm free on Thursday, and I made an appointment for a TEM test on Friday."

"Okay, then tell them to install in Zhangjiang tomorrow afternoon, and the on-site acceptance work will be handed over to you and Chen Wanqing. I will report the contact information of the two of you to their engineer later." After a pause, Wei Xingsi asked again:

"Trpl has been used for a few weeks, with a new computer, and there is no problem."

"There is no problem for the time being. I used the activation code Qiu Heming gave on the new computer, and now the software has become permanent." Xu Qiu said.

"In a while, I will use Teacher Tang's funds to pay for TRPL's equipment." After finishing speaking, Wei Xingsi took out a box of honey grapefruit tea from the small refrigerator behind him and handed it to Xu Qiu, "Then you Go ahead and call Duan Yun over by the way."

...

"Senior Brother Duan Yun, Teacher Wei is looking for you." Back at 216, Xu Qiu said straight to the point.

"Why are you looking for me?" Duan Yun stopped browsing the webpage and raised his neck.

"I don't know, maybe it's something about the experiment?" Xu Qiu guessed casually.

"I guess, it's mostly ideological education before leaving." Duan Yun sighed softly, picked up an experiment notebook from the table, with a black pen pinned to it, and headed to 218.

After more than ten minutes, Duan Yun came back, still carrying the notebook in his hand, but the position of the fountain pen on it has not changed, obviously he has never used it, when he walked to Xu Qiu's side, he said something expressionless , "Please ask me to bring a prophet, that is, ideological education."

Then he threw the experiment notebook on the table, returned to his seat and sat down, and whispered in Tian Qing's direction: "Get ready, he will come over soon."

At this time, except for Sun Wo who was testing the device in the laboratory, everyone else was at the desk at this time, Xu Qiu was reading the literature, and Wu Feifei was typing, preparing her summary.

Tian Qing was originally using her IPAD to catch up on dramas. After getting the news, she calmly took out two documents from the folder, picked up yellow and orange highlighters, and began to read and write.

Half a minute later, Wei Xingsi appeared at the door of 216 with his briefcase in his arms. He looked around and greeted everyone:

"I'm catching a flight tomorrow, so I have to go back early today, and I won't come to school tomorrow. Remember to close the doors and windows when you leave, and contact me in time if you have anything to do."

"Okay." Everyone nodded in agreement.

When the sound of Wei Xingsi's footsteps disappeared in the corridor, Duan Yun shouted excitedly, "Liberation." Apparently, the ideological education Mr. Wei gave him didn't have much effect.

However, Mr. Wei doesn't like detours. It would be embarrassing for a mentor who would turn around and see this scene.

Duan Yun raised his head, and Tian Qing inserted the two documents back into the folder, took out the ukulele from the cabinet next to it, and started playing, which sounded a bit like the tune of a certain classic saxophone song "Going Home" .

Even Chen Wanqing slacked off, moved her fingers and head, and stretched her waist.

After Teacher Wei left, the few people who usually stayed in Handan all got the DEBUFF that reduced their work efficiency by 20-100%.

Duan Yun looked at the time, and it was just half past eight, so he suggested, "How about we go out and play now?"

"He may call me later to inquire about the situation, and Chen Wanqing and Han Jiaying are not here today, so there are not enough people." Wu Feifei shook her head, and then she changed the subject, "However, if you want to go out to play, you can wait until tomorrow At night, he got on the plane, there was no signal, and it was absolutely safe at that time."

"It makes sense," Tian Qing echoed with a smile, "We haven't gone to sing for a long time, let's make an appointment tomorrow night, Xu Qiu, call Chen Wanqing and Han Jiaying back."

"Okay." Xu Qiu hesitated for a moment but nodded in agreement, "Tomorrow afternoon Zhangjiang will install a microwave reactor, but we should be able to come back before evening."

After all, this is also a rare team building activity in the research group. Usually, on Friday night or Saturday, everyone has their own arrangements, and it is difficult to get together. This kind of working day when Teacher Wei is not around, on the contrary, everyone available.

After get off work in the evening, the organic trio met at the school bus stop. Xu Qiu passed on the matter of the microwave reactor tomorrow and the team building to the seniors and the school girls, and the two said "team building is possible".

...

On Thursday morning, Xu Qiu entered the simulation laboratory II, and the tasks assigned to the simulation experimenters had been completed.

Among them, the first priority is to control the thickness of the transport layer molybdenum trioxide.

The previous standard thickness was 10 nanometers. Xu Qiu tested a range of 7-13 nanometers, with a gear of 0.5 nanometers, a total of 13 groups of conditions. Each condition made 3 batches of devices, and each batch of devices had 2 systems. The system made 3 repeated samples, a total of 234 battery devices.

The final results have been summarized by the simulation experimenters. The two systems of him and Xuemei have the highest device efficiency when the thickness of molybdenum trioxide is 12 nanometers and 12.5 nanometers, respectively, reaching 7.73% and 6.88%, the previous value 7.50% and 6.58% respectively.

The second priority is to regulate the preparation conditions of zinc oxide.

Because it is the second priority, the simulation experimenter automatically applied the conclusion of the first priority when exploring, that is, the thickness of molybdenum trioxide was adjusted to 12 nanometers and 12.5 nanometers respectively.

The results show that the annealing temperature of zinc oxide reaches 160 degrees Celsius, and the annealing time reaches more than 1 hour. Further increasing the annealing temperature or prolonging the annealing time will hardly affect the photoelectric performance of the battery device (the maximum efficiency and the average efficiency change range \u003c0.05%).

The film thickness of zinc oxide will have a slight impact on the device performance. The initial value is 5000r.p.m., and the film thickness is about 30 nanometers.

Xu Qiu experimented between 3000-6000r.p.m., with a gear of 250r.p.m., a total of 13 sets of conditions, and a total of 234 battery devices, but the batch was doubled.

As a result, the two systems of him and Xuemei have the highest device efficiency when the zinc oxide rotation speed is 4000r.p.m., which can reach 7.83% and 7.03% respectively.

Considering the actual device manufacturing conditions, it is very troublesome to use two kinds of molybdenum trioxide thicknesses, so Xu Qiu unified the new standard as "12nm molybdenum trioxide thickness, 4000r.p.m. zinc oxide speed".

At this time, the maximum efficiency of the school girl's system is slightly lowered to 7.00%.

The third priority is the attempt of positive structure devices. The highest efficiency of Xu Qiu's system has just broken 7%, which is not very competitive.

After leaving the simulation laboratory, Xu Qiu summarized today's results:

"The system of my junior and I both broke through 7%!"

"My system hit 7.83% and improved by another 0.33%."

"It is only the last step away from the world record of 8% (the actual value is 7.92%), and it is just a step away."

If you want to establish a new world record, you must be significantly higher than the original value. The results of 7.93% and 7.94% are tied at most.

At least it must start with 8, which is why Xu Qiu and Mr. Wei have always set 8% as the threshold.
