Chapter 370: Income after bedtime

"I have a scientific research support system novel ( to find the latest chapter!
"Yang Qin, how are you doing?" Lan He walked quickly from the laboratory next to him.
"I took them to watch our process of preparing the device." Yang Qin replied.
"That's good." Lan He smiled and looked at Xu Qiu's trio. Finally, his eyes fell on Xu Qiu, and said, "You are all experts in organic photovoltaics. Do you have any ideas?"
"I can't talk about it." Xu Qiu waved his hand and said modestly: "Let me mention 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, and then take it out when it is used. Do not keep it in the air, so the degradation of the 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 of "Madu Jiaotong University" LOGO, and began to record.
‘Is this a fleece in the group just before graduation? It's been half a year since I graduated, why do you still have a new book? Xu Qiu was taken aback for a moment, and 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, 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", and the subtext is "We have these materials, and if you want, you can contact our tutor."
Lan He understood Xu Qiu's suggestion: "I will discuss the matter with Teacher Wei." After speaking, he signaled Yang Qin and Xu Qiu to continue the discussion, and 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 vapor deposition equipment. The price is not expensive anyway. You can get a maximum of 200,000 yuan. It is better to make standard samples, and you can optimize the process step by step. Now your The device is three-step squeegee coating and one-step drip coating. It is not easy to control the variables for optimization, and the device efficiency is low, and it is difficult to determine which step is in addition to the problem."
Yang Qin responded: "I have already mentioned this to Lanhe. The evaporation equipment finally contacted a vacuum equipment company in Shencheng. The homogenizer is produced by a local company in Magic City."
Chen Wanqing said: "The evaporation equipment is from Shencheng? The equipment used by our research group is probably produced by the same company. This equipment is very easy to use, but the after-sales is a little troublesome. It is too far. , The difference between different manufacturers is not big..."
At this time, Lan He finished the phone call and went back to the crowd, saying, "I have already negotiated the materials. Teacher Wei said that Xu Qiu will be solely responsible for you. If we need any materials, you can draw a list. Come out and make an offer by the way."
"Quote?" Xu Qiu asked in confusion.
"It counts as our company buying your materials." Lan He smiled and explained: "Although I have a good relationship with Teacher Wei, my brothers have to settle accounts."
"Um...that's OK, I'll draw a list after the discussion is over." Xu Qiu nodded, thinking about what materials to provide and what price to set, while continuing to comment:
"Since the materials are interoperable, it is much easier to handle. For the ITIC and non-fullerene systems I mentioned before, you can try the less toxic tetrahydrofuran non-halogen solvent when scraping."
"The material is near-infrared absorption, that is, the ability to absorb visible light is very weak. It happens that you use silver nanowires here. You can prepare translucent devices. With different color donor materials, you can get colorful devices. For example, if you use PCE10 as a donor, it is blue, and if you use FTAZ, it is orange-red."
"In addition, for squeegee coating, optoelectronic materials are required to be too sensitive to the effective layer thickness. Our group has just developed a material X1 that can maintain the device efficiency above 10% when preparing 300nm thick films."
The first two points can be regarded as letting Blue River help them explore the process of translucent devices and non-halogen solvents. If successful, they can directly copy the skills by themselves, which can save a lot of energy.
The third point, X1, is actually IDIC. You still need to be a little cautious about unpublished work, so Xu Qiu did not reveal his real name.
After putting forward a few comments, Lanhe reminded: "Xu Qiu, there are also the materials we talked about and the quotation of materials."
Xu Qiu thought for a while and said: "For the time being, let's provide five kinds of materials. They are all self-developed materials in our group, including ITIC, X1, J1, and H43, each of which is 200 mg. The price is based on the market price. It’s easy to calculate for ten thousand per gram, and the total is ten thousand."
Although Blue River is not bad money, I bought PCE10 imported from Europe, 3W per gram of materials, but Xu Qiu felt that it could 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.
"Yes, then bring it over when you come next time." Blue River immediately made a decision, still looking rich, and added: "Will 200 mg be a bit less?"
"200 mg is enough for the time being," Xu Qiu responded hurriedly: "No matter how much it is, our group will not be able to get it out for a while.
"That's OK," Lan He nodded, and then asked: "By the way, Chen Wanqing, what do you think of our company?"
"Very good, the laboratory area is large, and the equipment is also good." In fact, science and technology companies usually have a lot of problems during their start-up. Blue River's company is no exception. The current subject of investigation, so she had no choice but to exaggerate.
Seeing that Xu Qiu and the others were planning to leave, Lan He looked at his watch and said, "Are you staying for dinner?"
"No, no."
"Ms. Wei wants us to go back soon."
Xu Qiu and Chen Wanqing declined Lan He's invitation. Han Jiaying seemed to be a little moved, but Xu Qiu was finally dragged away.
On the way back to the Handan campus, the three chatted.
Chen Wanqing opened the conversation first: "Blue River's company, how do you feel?"
Han Jiaying tilted her head: "Didn't they say that they would do flexible electronic printing before, how do you feel that they are planning to sell instruments?"
Xu Qiu joked:
One is a long-term goal and the other is a short-term goal for flexible electronic printing and selling instruments. There is no contradiction. And this is not the current popular model. First put forward a broad vision, and then you can hold the PPT. I found angel investors to invest in..."
Chen Wan gave him a clean look: "Be serious."
"Okay." Xu Qiu seriously analyzed:
"First of all, from the perspective of Blue River himself, I have looked through his circle of friends before and felt that he still thinks a lot, and they are all cutting-edge, indicating that he has a relatively strong ability to accept new things. For science and technology companies, it is still more important; moreover, as a rich second-generation boss, it is rare for Blue River to conduct experiments in the first-line laboratory.
"In addition, the doctoral student Yang Qin he asked for, I feel very reliable. The laboratory can be set up in six months, and now their scratch-coated device preparation process has already taken shape. The 4% efficiency of organic photovoltaic devices made from air is not low.
"From these points, Blue River's success rate is definitely much higher than those entrepreneurs who only speak PPT.
"But these days, those who are engaged in industry, emmm... There is a saying that it is not good, science and technology will rejuvenate the country, industry will be safe, no, it is real estate and finance...
"If Lanhe 1000W is given to me, I will definitely buy a house. I have seen that housing prices in the magic city will continue to rise for a few years. If the location is good, it is possible to double it in three years..."
Han Jiaying couldn't help reminding: "Brother, you are crooked again."
Xu Qiu scratched his head: "To sum up, the risk is not low, of course, the risk is relative. Sister, what salary does Lanhe offer you?"
Chen Wanqing thought for a while, and said: "The monthly salary is 18K, and there is an option worth 12K a month... In fact, leaving options aside, the salary is a little higher than the normal price."
"Indeed," Xu Qiu echoed: "If the company is not listed, it doesn't make sense to get the shares after the option is exercised, and I don't know how his option is converted. Maybe it is worth 7K. Here is it. Count 12K."
"That's no way." Chen Wanqing spread her hands: "There is still half a year. Let's wait and see. If you are recruiting from school, you may not be able to find a better job than this, female doctor of science and engineering, think It's too difficult to find a job for you. If you majored in computer science and became a program lady, you would definitely not worry about employment now. By the way, Xu Qiu, why didn't you study computer?"
Xu Qiu: "I, when I was a freshman, I was assigned to the first class of the technical science experiment class. A half of the class was a computer competition student, and every one of them wrote code. I felt that I couldn't compete, so I was in the sophomore year. When it came time, the computer option was first eliminated..."
"Okay." The senior sister agreed.
The three returned to the Handan campus. Xu Qiu received a WeChat transfer of 3,000 yuan from Lanhe and a message "Thank you, 1,000 for the consultation fee".
After sharing the consultation fee, Xu Qiu went to Room 218 and asked Wei Xingsi to report:
"Today I visited the company of Blue River. They prepared the device in the air by a full solution method. The transmission layer is PFN and PDINO. The electrode uses silver nanowires. The current PCE10: PCBM effective layer system is prepared by the scratch coating method. The effective layer and the transmission layer are prepared by the drip coating method, and the highest device efficiency reaches 4%.
"Also, I plan to give them five kinds of materials, ITIC, IDIC, J1, H43, 200 mg each. The price I gave is a total of 10,000 yuan."
"Okay, Blue River told me about this. After a while, he will pay the money directly." Wei Xingsi added: "According to the usual practice, this kind of laboratory sells materials and must be divided with the person in charge of synthesis. I won’t divide it up here, so 50% will be reserved for the research team's funds. You can withdraw directly after you go out for dinner and team building, and you can allocate the other 50% to the person responsible for the synthesis.
"Yes," Xu Qiu nodded and said, "By the way, Teacher Wei, I have an idea."
"Oh? What do you think?" Wei Xingsi suddenly became interested. Historical experience told him that whenever Xu Qiu said this, he would always surprise him.
"Our group has now developed a lot of non-fullerene acceptor materials and wide band gap donor materials. I think it might be possible to cooperate with Blue River to start a photoelectric materials company." Xu Qiu didn't say the whole thing. , Because theoretically, this is a win-win situation for all three parties, but he is not sure about Wei Xingsi's attitude.
Wei Xingsi touched his chin and fell into contemplation. After a few seconds, he said: "This idea is good, you can do it, but we will keep a low profile here and only provide technical guidance. Don't show up too much. I will ask later. On the Blue River, see if he has any intentions and how to allocate shares."
After talking about this matter, Xu Qiu took a bottle of Evian water and returned to 216.
In general, Wei Xingsi is relatively cautious, and may be afraid that too high-profile will cause unnecessary risks~EbookFREE.me~ However, the problem is not big, as long as the quality of the synthesized materials can be guaranteed, even if Wei Xingsi is not used If you personally promote it, someone will buy it.
After all, now that the insiders start their own companies, they can know where their G-spots are and what materials they need most.
There is a saying that men are the ones who know men best, just like when watching a live broadcast, they know that it is a cute girl, and many people will still welcome men.
In addition, Xu Qiu estimates that he can get some shares if he cooperates with him to start a new company. Although it is certainly not too much, he can finally make money lying down.
Now, don’t you talk about side jobs, income after going to bed? Thinking about it, it’s quite comfortable.
