I Have a Research Support System

"Yang Qin, how are you doing?" Lan He quickly walked over from the nearby laboratory.

"I showed them the process of our device preparation." Yang Qin replied.

"That's good." Lan He looked at Xu Qiu and the others with a smile, and finally fell on Xu Qiu, and said, "You are all experts in organic photovoltaics, what's your opinion?"

"I can't talk about high opinions." Xu Qiu waved his hand and said modestly: "Let me make two points first, first of all, the prepared solution, especially the effective layer solution, should be stored in the glove box as much as possible first, and then take it out and apply it when it is used. Do not leave it in the air all the time, so that the degradation of device performance may be lower, and the shelf life of the solution will be longer."

Yang Qin nodded, took out a brand-new experiment notebook with the school name and LOGO of "Madou Jiaotong University" printed on it, and started recording.

‘Is this a plucking in the group before graduation? It's been half a year since I graduated, why do I still have a new notebook? ’ Xu Qiu was stunned for a moment, then continued:

"In addition, the air stability of the PCE10:PCBM system is too poor. You can consider using non-fullerene acceptor materials... ITIC or IEICO, if you want to find references, just search according to the method I said before."

Xu Qiu looked at Lanhe, and added: "These two systems were developed by our team", the subtext is "We have all these materials, if you want, you can contact our instructor".

Lan He understood Xu Qiu's hint: "As for the material, I will discuss it with Teacher Wei." After speaking, he signaled Yang Qin and Xu Qiu to continue the discussion, while he walked aside and dialed Wei Xingsi's phone.

Chen Wanqing continued to suggest: "It is best to equip a set of spin coating and evaporation equipment. Anyway, the price is not expensive, and you can get it at most 200,000 yuan. This is better for making standard samples, and you can also optimize the process step by step. Now your The device is three-step scrape coating, one step drop coating, it is difficult to control variables for optimization, the efficiency of the device is low, and it is difficult to determine which step is the problem."

Yang Qin responded: "I have already mentioned this to Lanhe. The evaporation equipment finally contacted a vacuum equipment company in Shencheng. The glue dispenser is produced by a local company in Shanghai."

Chen Wanqing said: "Is the evaporation equipment from Shencheng? It is estimated to be produced by the same company as our research group. The equipment of this company is very easy to use, but it is a bit troublesome after sale. It is too far away. For the coating machine , the difference between different manufacturers is not big..."

At this moment, Lan He returned to the crowd after finishing the phone call, and said, "I've already settled the matter of the materials. Teacher Wei said that Xu Qiu will be fully responsible for you. If we need any materials, you can just make a list." Come out and quote a price by the way."

"Quotation?" Xu Qiu asked doubtfully.

"It counts as our company buying your materials." Lan He explained with a smile: "Although I have a good relationship with Mr. Wei, brothers have to settle accounts clearly."

"Well... that's fine. I'll make a list after the meeting is over." Xu Qiu nodded, thinking about what materials to provide and what price to set, while continuing to make suggestions:

"Since the materials are interoperable, it will be much easier to handle. The ITIC and IEICO non-fullerene systems I mentioned before, you can try the less toxic tetrahydrofuran non-halogenated solvent when scraping and coating."

"IEICO material absorbs near-infrared, that is, it has very weak absorption ability for visible light. It just so happens that you use silver nanowires here, which can be used to prepare translucent devices. With donor materials of different colors, colorful devices can be obtained. , For example, if you use PCE10 for the donor, it will be bluish, and if you use FTAZ, it will be orange-red.”

"In addition, for scrape coating, photoelectric materials are required to be too sensitive to the thickness of the effective layer. Our group has just developed a material X1. When preparing a 300-nanometer thick film, the device efficiency can still be maintained above 10%."

The first two points are for Blue River and the others to help explore the process of translucent devices and non-halogen solvents. If they succeed, they can directly copy the skills themselves, which can save a lot of energy.

The third point, X1, is actually IDIC. For unpublished work, we still need to be a little cautious, so Xu Qiu did not reveal his real name.

After putting forward a few comments, Lan He reminded: "Xu Qiu, there are also the materials we talked about before and the quotation of materials."

Xu Qiu thought for a while and said: "Let's provide five kinds of materials for the time being, all of which are self-developed materials in our group, including ITIC, IEICO, X1, J1, H43, 200 mg each, and I will list the prices according to the market price. Each kind is calculated at 10,000 per gram, which is relatively easy to calculate, and the total is 10,000."

Although Blue River was really not short of money, they bought PCE10 imported from Europe, 3W yuan per gram of materials, but Xu Qiu felt that it should not be too dark, so he quoted a market price.

Moreover, this cooperation also gave Xu Qiu a new idea, and he planned to go back and discuss it with Wei Xingsi.

"Okay, then bring it with you when you come over next time." Lan He immediately made a decision, and added with a look of wealth and wealth: "Is 200 mg a little little?"

"200mg is enough for the time being," Xu Qiu hurriedly responded, "If there is more, our team won't be able to produce it for a while."

"That's fine," Lan He nodded, and then asked, "By the way, Chen Wanqing, what do you think of my company?"

"It's pretty good, the laboratory area is very large, and the supporting equipment is also good." In fact, science and technology companies usually have many problems during their start-up period, and Blue River's company is no exception. The current investigation object, so she had no choice but to boast a few words.

Seeing that Xu Qiu and the others showed signs of leaving, Lan He looked at his watch and said, "Are you staying for dinner?"

"No, no."

"Teacher Wei told us to go back early."

Xu Qiu and Chen Wanqing declined Lan He's invitation politely, Han Jiaying seemed a little moved, but Xu Qiu pulled her away in the end.

On the way back to the Handan campus, the three chatted.

Chen Wanqing opened up the conversation first: "Lanhe's company, how do you feel?"

Han Jiaying tilted her head: "Didn't they say they were going to do flexible electronic printing before, how does it make me feel now... are they planning to sell instruments?"

Xu Qiu joked: "Flexible electronic printing and selling instruments, one is a long-term goal, the other is a short-term goal, there is no contradiction. And this is the current popular model. First put forward a broad vision, and then you can hold the PPT Looking for angel investors to attract investment..."

Chen Wan gave him an innocent look: "Be serious."

"Okay." Xu Qiu analyzed seriously:

"First of all, from the perspective of Lan He himself, I looked through his circle of friends before, and I feel that he still thinks a lot, and he is very cutting-edge, which shows that he has a relatively strong ability to accept new things. For science and technology companies, it is quite important; moreover, as a rich second-generation boss, it is quite rare for Lan He to conduct experiments in front-line laboratories.

"In addition, Yang Qin, a doctoral student he found, I think is very reliable. The laboratory can be set up in six months, and now their scratch-coating device preparation process has already taken shape. After all, for full solution , Organic photovoltaic devices prepared in air, the efficiency of 4% is not low.

"From these points of view, the success rate of Blue River is definitely much higher than those entrepreneurs who can only speak PPT.

"But these days, those who are engaged in industry, emmm... There is a saying that is not good, science and technology will rejuvenate the country, industry will stabilize the country, no, real estate will rejuvenate the country, and finance will stabilize the country...

"If Blue River's 1000W is given to me, I will definitely use it to buy a house. According to what I've seen in the past few years, the house price in Shanghai will continue to rise. If the location is good, it may double in three years..."

Han Jiaying couldn't help reminding: "Senior brother, you're on the wrong side again."

Xu Qiu scratched his head: "To sum up, the risk is not low. Of course, the risk is relative. Sister, what salary does Lan He offer you?"

Chen Wanqing thought for a while and said, "The monthly salary is 18K, and there are options worth 12K per month... In fact, the salary is a little higher than the normal price without the options."

"Indeed," Xu Qiu echoed, "If the company isn't listed, it doesn't make much sense to get the shares after the options are exercised, and I don't know how his options are converted. Maybe it's worth 7K, here you are. Count 12K."

"That can't be helped." Chen Wanqing spread her hands: "There is still half a year, let's wait and see. If you go to the school again, you may not be able to find a better job than this. Female doctor of science and engineering, think It is too difficult to find a suitable job. If I had majored in computer science and became a programmer, I would definitely not have to worry about employment now. By the way, Xu Qiu, why didn’t you study computer science?”

Xu Qiu: "I, when I was a freshman, I was assigned to the first class of the technical science experiment class. A small half of the class were recommended students for computer competitions, and everyone wrote codes. At the time, I first ruled out the computer as an option..."

"Okay." The senior sister agreed.

When the three of them returned to the Handan campus, Xu Qiu received a WeChat transfer of 3,000 yuan from Lanhe, as well as a message "Thank you, the consultation fee is 1,000 yuan per person".

After sharing the consultation fee, Xu Qiu went to room 218 and reported to Wei Xingsi:

"Today I visited Blue River's company. They prepare devices in the air by the full solution method. The transport layer is PFN and PDINO. The electrode uses silver nanowires. The current PCE10:PCBM effective layer system is prepared by scrape coating method. The effective layer and the transport layer were prepared by drop coating method, and the highest device efficiency reached 4%.

"Also, I plan to give them five kinds of materials, ITIC, IEICO, IDIC, J1, H43, 200 mg each, and the quotation I gave is 10,000 yuan in total."

"Okay, Lan He told me about this matter, and he will send the money directly after a while." Wei Xingsi added: "According to the usual practice, when this kind of laboratory sells materials, it needs to be shared with the person in charge of synthesis. I won’t share it here, so 50% will be reserved for the research team’s funds, you can directly withdraw it when you go out for dinner and team building, and you can share the other 50% with the person in charge of the synthesis.”

"Okay," Xu Qiu nodded and said, "By the way, Teacher Wei, I have an idea."

"Oh? What do you think?" Wei Xingsi immediately became interested. Historical experience told him that whenever Xu Qiu said that, it would always surprise him.

"Our group has developed a lot of non-fullerene acceptor materials and wide bandgap donor materials. I think maybe we can cooperate with Blue River to start a photoelectric material company." Xu Qiu didn't say the whole thing. , because theoretically speaking, this is a win-win situation for all three parties, but he is not sure about Wei Xingsi's attitude.

Wei Xingsi stroked his chin, fell into deep thought, and after a few seconds, said: "This idea is good, and it can be done, but we will keep a low profile here, only provide technical guidance, and don't make too much publicity. I will ask later. Over at Blue River, let's see if he has any intentions, and how to distribute the shares specifically."

After talking about this matter, Xu Qiu took a bottle of Evian water and returned to 216.

In general, Wei Xingsi is quite cautious, maybe he is afraid that too high a profile will cause unnecessary risks.

However, the problem is not too big, as long as the quality of the synthesized materials can be guaranteed, even if Wei Xingsi doesn't need to promote it himself, there will be people who will buy it.

After all, now that an insider starts his own company, he can know where the G-spots of his peers are and what materials are most needed.

There is a good saying that men know men best, just like when watching a live broadcast, many people will still welcome men when they know she is a cute girl.

In addition, if they cooperate to start a new company, Xu Qiu reckons that he can get some shares. Although it is definitely not too much, he can make money lying down after all.

Don't they talk about side jobs now, income after sleep? Thinking about it is quite comfortable.
