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

"Oh, the two of them are doing compositing in Zhangjiang." Xu Qiu chats with school girls every day, knowing their current situation very well, and helping them reply:

"Han Jiaying is working on 3D-PDI materials. Previously, he only obtained tens of milligrams of products. Now it is being prepared in large quantities. Chen Wanqing has obtained 1,3-indenedione raw materials and is synthesizing a newly designed A-D-A molecule, CH1.

Wei Xingsi nodded noncommitantly, and suddenly said: "Speaking of synthesis, the microwave reactor contacted me today. Their engineer happened to be in Magic City recently and asked us if we can install it this Thursday or Friday. The time is awkward. It happened to be stuck after I went abroad, and someone had to accept the instrument when installing the instrument. Are you free these two days? If it doesn't work, I will push it away first and make an appointment when I come back."

'The school girl's current system may need to use a microwave reactor. If it is not installed this time, I don't know when it will be delayed. After all, their engineers are running around the country and will not stay in the magic city. , If it is just accepted, there should be no problem. ’

After thinking for a moment, Xu Qiu took the matter down: "I'm free on Thursday, and I booked a TEM test on Friday."

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

"TRPL has been used for a few weeks, with a new computer, there is nothing wrong with it."

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

"After a while, I will use the funds from Teacher Tang to settle the TRPL instrument money." After speaking, Wei Xingsi took out a box of honey grapefruit tea from the small refrigerator behind and handed it to Xu Qiu, "Then you Go ahead and call me Duan Yun by the way."

...

"Senior Brother Duan Yun, please look for Teacher Wei." Back at 216, Xu Qiu said straightforwardly.

"Why are you looking for me?" Duan Yun stopped scanning the webpage, tilting his neck.

"I don't know, it's probably an experiment?" Xu Qiu guessed at will.

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

More than ten minutes later, 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 not used it. When he walked to Xu Qiu's side, he said blankly. "Please ask me to bring a prophet, it 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: "Be prepared, he will come over soon."

At this time, except Sun Wo 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 in the codeword, preparing her review.

Tian Qing was originally using the IPAD to chase the drama. After receiving the news, she took out two documents from the folder without a hassle, picked up the yellow and orange highlighters, and began to read and write.

After another half minute, Wei Xingsi appeared at door 216 with a briefcase. He looked around and greeted everyone:

"Tomorrow I will catch a plane, 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 any issues."

"Good." Everyone nodded in response.

When Wei Xingsi's footsteps disappeared in the corridor, Duan Yun shouted in excitement, "Liberation." Obviously, the ideological education that Teacher Wei gave him before did not have much effect.

However, that is, Teacher Wei doesn't like twists and turns. It would be embarrassing to change his head to see this scene with another instructor who would kill the carbine.

Duan Yun raised his head, Tian Qingshun inserted the two documents back into the folder, took out the ukulele from the cabinet next to him, and played it. It sounded a bit like the tune of a classic saxophone song "Homecoming". .

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

After Mr. Wei left, the few people who usually stayed in Handan received DEBUFF, which reduced their work efficiency by 20-100%.

Duan Yun looked at the time, and at half past eight, he suggested: "How about we go out to play now?"

"He might call me later to ask about the situation, and Chen Wanqing and Han Jiaying are not there today. The people are not together." Wu Feifei shook her head, and then her conversation changed. "However, if you want to go out to play, you can wait for tomorrow. At night, he got on the plane and there was no signal. It was absolutely safe then."

"It makes sense," Tian Qing agreed with a smile, "We haven't been singing for a long time. Let's make an appointment tomorrow night. Xu Qiu, you call Chen Wanqing and Han Jiaying back."

"All right," Xu Qiu hesitated for a while and nodded in agreement, "Tomorrow afternoon, Zhang Jiang will install a microwave reactor, but it should be possible to come back by night."

After all, this can be regarded as a rare team building activity for the research group. Normally, on Friday night or Saturday, everyone has their own arrangements and it is difficult to get together. This kind of workday when Teacher Wei is absent, on the contrary, everyone does Free.

After get off work in the evening, the organic trio nodded in the school bus. Xu Qiu conveyed the microwave reactor and team building issues to the school sisters and younger sisters. The two said that "team building can be done."

...

On Thursday morning, Xu Qiu entered the simulation laboratory II, and the task assigned to the simulation experimenter was completed.

Among them, the first priority is to regulate the thickness of the molybdenum trioxide of the transmission layer.

The previous standard thickness was 10 nanometers. Xu Qiu tested a range of between 7 and 13 nanometers, each with a range of 0.5 nanometers, and a total of 13 sets of conditions. Each of the conditions makes 3 batches of devices, and each batch of devices has 2 systems. The system makes 3 repeated samples, a total of 234 battery devices.

The final result, the simulation experimenter has made a summary, the two systems of him and Xuemei, when the thickness of molybdenum trioxide is 12 nm and 12.5 nm, the device efficiency is the highest, reaching 7.73% and 6.88%, respectively. Respectively 7.50% and 6.58%.

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 nm and 12.5 nm 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 extending the annealing time will hardly affect the photovoltaic performance of the battery device (the highest efficiency, the average efficiency change range is 0.05%).

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

Xu Qiu experimented between 3000-6000r.p.m., one gear per 250r.p.m., a total of 13 sets of conditions, also a total of 234 battery devices, but the batch is doubled.

In the end, the two systems of him and Xuemei both had the highest device efficiency when the zinc oxide speed was 4000r.p.m., reaching 7.83% and 7.03% respectively.

Taking into account the actual device preparation conditions, it is very troublesome to apply two kinds of molybdenum trioxide thickness, Xu Qiu set the new standard uniformly as "12nm thickness of molybdenum trioxide, 4000r.p.m. zinc oxide rotation speed".

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

The third priority is the trial of positive structure devices~www.ltnovel.com~Xu Qiu's system, the highest efficiency is just broken 7%, which is not competitive.

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

"My school girl and I both exceeded 7%!"

"My system reached 7.83%, an increase of 0.33%."

"The world record of 8% (the actual value is 7.92%) is just the last step, and it's a knock."

To stand firm on the new world record, it 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. This is why Xu Qiu and Wei Teachers always use 8% as the threshold.
