I Have a Research Support System

Text 394 Start an associate professor (for subscription)

Xu Qiu was dragged by Lan He to chat for a long time. He started talking about artificial intelligence from "Neural Networks and Deep Learning", and then moved to the rule of man and the rule of law...

Most of the time, Lan He was speaking and Xu Qiu was listening.

Xu Qiu estimated that he should be no less than Lanhe if he reads a single essay. After all, he used to read novels at night when the number of words was calculated in 100 million.

However, from the perspective of the amount of information contained in the text, Blue River is definitely better.

Therefore, Xu Qiu listened more carefully.

In addition, he is also to learn more about Blue River as a person, after all, he is a partner.

Xu Qiu's impression of Blue River was only through meeting a few times, eating a meal, and flipping through the circle of friends. It might be a bit biased. Only by communicating more can we get to know a person deeply.

For example, he and his school sisters often talked in the night and discussed life together, and they understood each other a lot, to the extent that you know my length and I know your depth.

The two talked for more than half an hour, and Xu Qiu found that Lan He was quite capable of bragging despite other abilities.

Speaking of it, it is a set of sets. After listening to it, Xu Qiu feels: "Wow, this field is about to rise. Qiandu's entry into the field of artificial intelligence is really a wise choice. what."

Until Blue River talked about the photovoltaic field that Xu Qiu was familiar with, it was revealed in an instant. Many places were not very rigorous. For example, laymen and even some insiders have been talking about it, or wrote in the article: " Low cost of organic photovoltaic devices".

In fact, the concept of low cost in the field of organic photovoltaics is something in the era of p3ht and ppv (poly-phenylene vinylene) derivatives.

Up to now, the cost of organic photovoltaic materials has become higher and higher, and it is difficult to call it "low cost".

At this stage of the new high-efficiency system, just take out one, whether it is a pce10 donor or an itic acceptor, even if stability and other issues are not considered, the cost alone is inferior to the current commercial silicon solar cells.

This is sometimes the case for scientific research. The earliest development of organic photovoltaics may be based on cheap prices. Later, in the research process, researchers found that high efficiency and low cost could not be balanced. After weighing them, they decided to pursue efficiency first. Posting articles, the molecules become more and more complex, and the cost naturally becomes higher and higher.

Many people have not changed their previous concepts because of their ideological inertia, and have been using what they said more than a decade ago.

Of course, if you forcibly talk about low cost, it is not impossible to talk about it.

For example, it is claimed that organic photovoltaic devices are usually 100-nanometer thick devices, while silicon cells are 200-micron devices. For devices with the same area, the material consumption varies by a thousand times.

Insert a sentence, [\\mi\\mi\\reading\\app\\\\] It’s really good, it’s worth installing, even Android and Apple phones support it!

The unit price of organic photovoltaic materials has a great chance of achieving one-thousandth of the unit price of silicon materials, so the cost of organic photovoltaic devices is lower.

In fact, it is impossible to convert all materials into thin films regardless of methods such as spin coating, blade coating or "slot-die". In this conversion process, the amount of loss may be very large.

Like the traditional spin-coating method in the laboratory, the ratio of the photovoltaic material in the solution to the effective layer film may be less than 10%, that is, more than 90% are wasted.

However, it is difficult to prepare a thin film with a stable film thickness of about 100 nanometers if it is scraped, "slot-die" and other methods. Usually thick films are prepared directly, such as 300 nanometers. This is also to some extent It is a waste, and it will also lower the conversion efficiency of the device.

After all, not all organic photovoltaic materials are compatible with thick film and large size.

But in any case, Blue River talked about this set of things, if you make a ppt, it should be no big problem to fool investors.

Most investors do not know what the specific experimental process is like, just as the general public does not know what the scientific research circle is like.

Seeing that Blue River had to change to the next field to continue the exchange, Xu Qiu took the initiative to resign. He was afraid that he would be stayed for half an hour if he didn't leave: "Well, I'll go see the situation of other people."

"Okay, just come and find me if you have something." Lan He nodded and sent Xu Qiu to the door of the office.

Xu Qiu saw the large office outside, and now there was only the new employee wearing a gray jacket and gray casual trousers. The other person was typing on the keyboard. After hearing the sound, he looked up, then lowered his head and continued on. work.

This should be the new programmer. Xu Qiu ignored him and went straight to the device laboratory.

At this time, Chen Wanqing was operating the squeegee machine in the glove box, and several Blue River employees were also busy.

Yang Qin, Xuemei, and the other employee doing organic synthesis are not here. They are probably doing synthesis experiments in another organic laboratory.

According to the previous idea given to her by Xu Qiu, the senior sister brought several tens of milligrams of materials such as j1, h22, -4cl from Teacher Wei’s research group, and all the solutions have been prepared, and the transmission layer material is now being scraped. .

Seeing Xu Qiu, Chen Wanqing asked casually, "Have you talked for so long?" while operating the squeegee equipment.

"I didn't expect Blue River to be talking about tuberculosis." Xu Qiu replied helplessly, then copied the latest squeegee machine to the simulation laboratory and watched the senior sister operate it.

"It looks pretty good." Chen Wanqing picked up a scratch-coated pf substrate with tweezers and showed it to Xu Qiu.

"Well, the blade runs very steadily," Xu Qiu observed the substrate for a while, and continued to comment: "Although you can still see uneven thickness in the scraped film, it is not as obvious as before. The effect has improved a lot."

"Yes, compared to the last time I came here, they have improved the instrument a lot. It is said that it has been iterated to version 1.3.2." Chen Wanqing paused and said, "Now I think you have set 7% There is still a chance to achieve the 8% goal."

"Then I will wait for your good news." Xu Qiu said with a smile.

On the device laboratory side, there is not much to be concerned about except for the squeegee machine.

As for the two new instruments purchased, the homogenizer is a normal model without integrated thermal spin coating function. It is the type eliminated by Mr. Wei’s research team. The vapor deposition equipment manufacturer is the same as that of Wei Xingsi’s research team, but is blue. The models on the river side are newer, but they do not integrate any special functions.

So Xu Qiu stopped for a while and walked to the organic laboratory next to him.

Han Jiaying and the others are here. At this time, they are conducting low-temperature experiments, which looks like a reaction of introducing aldehyde groups on the idtt unit.

"Brother, you are here~" the school girl greeted cheerfully.

"This is our newly recruited master, Zhang Ren." Yang Qin also took the initiative to introduce.

"Xu Qiu, hello." Zhang Ren said hello shyly.

"Well, hello." Xu Qiu and Zhang Ren said hello, smiled at the school girl, and then chatted with Yang Qin: "How is the progress now?"

"I used to do two kinds of units, idtt and i. Now they each have about ten grams of high-purity monomers. Next, I plan to try to synthesize itic." Yang Qin paused and said, "What we are doing today is the key The reaction of **** idtt introducing aldehyde groups is only two steps away from getting itic materials."

"It's progressing pretty fast." Xu Qiu calculated it. It has only been three weeks since the establishment of the company. Yang Qin has almost obtained the itic materials, and the experiment is already very fast.

Although Yang Qin repeats the wheel made by Xu Qiu, he also started from scratch. This shows that he basically didn't paddle, and he may even work overtime. Perhaps Blue River promised him any benefit. Under the reward, there must be a brave husband. Well.

There are three new fume hoods in the organic laboratory, and a lot of new instruments, including a relatively advanced high-pressure liquid chromatograph, which can run four columns at the same time, which is more suitable for this kind of enterprise-level mass preparation Material, but also comes with purity analysis function.

There is also an infrared spectrometer, which is also used to characterize the purity of the product. After all, the materials that are now made are for sale, and a purity verification report is required to make users feel at ease.

In addition, there is a microwave reactor, also of the cem brand, to speed up the reaction.

Xu Qiu had to sigh that the conditions of the company are still good.

These two laboratories have newly added fume hoods and instruments, and the total price is conservatively estimated to exceed 1 million. This is much more generous than universities.

In universities, the distribution of scientific research funding is actually very uneven.

In fact, most research groups don’t have much funding. 1 million is a lot of money. Many associate professors’ research groups don’t have a total of 100,000 instruments. When doing experiments, they use various school public platforms. instrument.

There is an associate professor at the beginning, only an office, no funds, no students, and all experiments rely on rubbings.

This is the true portrayal of green pepper scholars.

Wei Xingsi now has less money left for the project. The total funding for the total amount of money is only a few hundred thousand ~ www.ltnovel.com~ If the key projects and the Jieqing Fund cannot be applied later, the development speed of the research team will be Slow down.

Many things need money to solve, it must be solved with manpower and time.

Of course, it is not without a solution. For example, go to Gong Yuanjiang to fight the autumn wind with other research groups.

One day passed.

Chen Wanqing has successfully prepared three kinds of full-solution processing, translucent, scratch-coated, flexible, and colorful devices. Among them, the pce10:-4cl system is the best with an efficiency of 6.17%.

The elder sister tried it for the first time, and was close to the 7% target value, indicating that this system is still very promising.

Xu Qiu and Han Jiaying were mainly busy with organic synthesis. They took Yang Qin and they successfully obtained the idtt-cho material, and they were able to synthesize the final itic in just one step.

The final reaction is not difficult, that is, pyridine is needed, which is more flavorful. This is done by Yang Qin.

Before leaving, Xu Qiu talked to Yang Qin again and told him what to do next: "After the itic is successfully synthesized, first prepare it temporarily, because itic is already being done by someone now, and it is not competitive enough to use it alone. , So we have to turn our main energy to the -4f system."

"This -4f material is the representative of the near-infrared system. The material in Chen Wanqing's article broke the current world record of efficiency in the field of organic photovoltaics with an efficiency of 12.3%. We waited for Chen Wanqing's article to be published, and we will use this as a selling point. Fired the first shot of our company’s products."

Yang Qin: "Understood!"
