I Have a Research Support System

After the group meeting, the organic group of five held a brief meeting to discuss the division of labor for the next work.

Now, the internal personnel structure of the organic five-member group follows the principle of those who achieve first, with Xu Qiu as the leader, not only in charge of his own project, but also in charge of coordinating other people.

Under Xu Qiu are Chen Wanqing and Han Jiaying. Both of them have mastered various testing and characterization skills in the field of organic photovoltaics, and they have accumulated enough literature. They can carry out projects alone and have the ability to guide other people's experimental operations.

Next are the newcomers Wu Shengnan and Mo Wenlin. Under the guidance of Xu Qiu, Wu Shengnan has done more synthesis of ADA-type receptors, and other characterization and literature accumulation are slowly being supplemented; Mo Wenlin's experimental experience is almost It is zero, and I have only just learned about device preparation, but I have been trained by Gong Yuanjiang for a period of time, and I have read a lot of literature in the field of organic photovoltaics.

At present, Xu Qiu's main task is to concentrate on writing two articles based on the PCE10:ITIC and H22:ITIC systems.

Chen Wanqing's IEIC system is basically completed, and she is busy with various characterizations of the IEICO system, so she can teach Wu Shengnan and Mo Wenlin by the way.

Wu Shengnan, Mo Wenlin and Han Jiaying are responsible for making devices, including three new receptor systems, ternary system and H4x system.

Among them, Wu Shengnan and Mo Wenlin conducted experiments in rotation. They evaporated a batch of devices every day, each batch of devices was about 20 pieces, and all the systems to be done were put together, regardless of each other. Han Jiaying was responsible for assistance and teaching.

Speaking of the ternary system, since Mo Wenlin made a batch of H22:ITIC:PCBM systems by mistake last week and obtained devices exceeding the binary system, Xu Qiu also started to develop the ternary system in the simulation laboratory. The performance has been explored, and now the preliminary results have been obtained.

It is true that some ternary systems have higher efficiency than the original binary system, but the final efficiency did not exceed 12%.

Therefore, this strategy is only a small path for the time being, and honestly developing new donor and acceptor materials and making binary devices is the kingly way.

However, from the perspective of posting articles, there are still some tricks.

This part of Xu Qiu's plan is to be handed over to Mo Wenlin. How many articles can be published depends on her ability.

In the afternoon, before starting the experiment, Han Jiaying raised a question: "Should we continue with the ITO substrate with new patterns? Yesterday's test results were not very good..."

Xu Qiu thought about the difficulty of replacing the mask, and immediately said: "No need to replace, just use your existing system to try it out. During the test, use 0.09% square centimeter and 0.01 square centimeter mask, and take ten sets of data each. .”

In fact, there is really no need to replace the original old substrate. Thousands of tests have been carried out in the simulation experiment system. The results show that the advantages of the new substrate far outweigh its disadvantages, but others do not know it for the time being. .

Xu Qiu had established prestige in the organic group of five, seeing that he had made a decision, no one expressed any objection.

Han Jiaying turned her head and said, "Sister Wu Shengnan, the first batch of you come first."

"Yes." Wu Shengnan nodded slightly.

After they left and entered the laboratory, Xu Qiu was also thinking about other problems that the new substrate might bring.

After much deliberation, it seems that there is nothing that needs to be changed.

The probe device when testing the J-V curve, and the sample holder when testing CELIV and EQE, these devices related to the substrate pattern do not need to be replaced.

Because originally based on the old substrate there were eight probes, three on the left and three on the right, and one on the front and one on the back. Now the new pattern only needs to connect one probe contact on the top and bottom of the substrate. A group or a group before and after can be used.

If the pattern of the substrate was changed to the windmill shape of Gong Yuanjiang and the others, then the position of the eight probes would need to be redesigned.

However, of the two sample holders in the laboratory, one of the sample holder's probes fell off two and needed to be repaired.

After discovering this situation before, because there is another sample holder for spare, it will not affect the use temporarily, so it has been delayed.

Now that Xu Qiu remembered this matter, he decided to simply resolve this matter.

Wu Feifei asked a professor from the Department of Physics to do the sample tray before, and the other party opened a small company, and occasionally took private orders to make some extra money.

This kind of situation is not uncommon in the science and engineering departments of universities. After all, they are doing side jobs these days. The salary of the main job professor alone is not enough in a first-tier city like Shanghai. The probability is not as good as that of elite code farmers. many.

In fact, Wei Xingsi and Xu Qiu could also set up a company, synthesize the materials they developed and sell them in batches, and compete with the one in Shencheng and other optoelectronic companies for business.

With a large number of research results as endorsements, Wei Xingsi can still get a lot of business by advertising in the industry himself. After all, the company opened by the material developer sounds guaranteed.

However, Wei Xingsi doesn't pay much attention to money. He has a big house in Shanghai, millions of savings, a stable teaching position, and he is 40+ years old. He has basically enjoyed what he should enjoy, and can meet his usual basic material needs. However, money has little driving force for him, and he wants to pursue a career, that is, to make a breakthrough in scientific research.

Therefore, more than half of the bonuses and dinners he usually gives to students are actually his own money. After all, not everything can be reimbursed by the school.

Xu Qiu has no such idea for the time being. Maybe he will participate in the field of organic photovoltaics when the research in the field of organic photovoltaics matures and moves towards application, but not now.

Now is the time to spend money to buy time. If you exchange your own time for money instead, you will be putting the cart before the horse.

Xu Qiu asked Wu Feifei for contact information, contacted the student of the physics professor, and then sent Han Jiaying to deliver the samples.

At four o'clock in the afternoon, the first wave of devices prepared by Wu Shengnan had been evaporated and tested.

Xu Qiu heard the voices of "Wow~", "11%!", "It's increased again!" from time to time in the direction of the laboratory, and couldn't help smiling, thinking to himself: "11% is from my side Last week’s results, the latest system has already exceeded 12% yesterday.”

Not long after, Han Jiaying jumped out of the laboratory and announced the good news to Xu Qiu: "Brother, guess how many test results we have reached now?"

Xu Qiu scratched her nose and said, "You shouted so loudly that you could hear it from a long distance away. It must have broken 11%."

Han Jiaying smiled and said: "So far, five systems have been tested, and the results obtained with a small area of ​​0.01 square centimeters show that the device efficiency has exceeded 10%, and two systems have broken through 11%. H43: ITIC, and brother's H22: IT-4F."

Wu Feifei, Duan Yun, and Tian Qing were all sitting at the desk at this time. After hearing the result, they all cast envious eyes.

In fact, Duan Yun and Tian Qing were fine. These two salted fish didn't have much pursuit of articles.

But Wu Feifei's expression is a bit complicated. She and Xu Qiu's research fields are different. She has always been a bystander, watching Xu Qiu step by step from the beginning of a scientific research rookie to gradually emerging, and then in scientific research. On the one hand, he has overshadowed her in the limelight, and now he is leading a team of five to continuously make breakthroughs, and it can be expected that he will go further in the future.

PS: It's another day of thousands of days. Currently, I owe 3W3, and I have already repaid 2W7, which is still 6K short.
