Chapter 368: The banknote ability is still fierce

"I have a scientific research support system novel ( to find the latest chapter!
In the evening, Xu Qiu and Sun Yifan had dinner together and contacted each other, and then he returned to Caiyi 216 alone.
Not long after sitting down at the desk, Xu Qiu received a WeChat message from Blue River: "Is there any time to come to our company in the past few days? I have already talked about it with Teacher Wei."
He didn't rush to reply, first discussed with Han Jiaying and Chen Wanqing, and finally decided that it is better to hit the sun than to choose a day, and set the time to be tomorrow afternoon, Tuesday afternoon.
Xu Qiu replied: "Tomorrow at two o'clock in the afternoon."
Blue River: "Okay, this is the location of my company."
Later, he sent another positioning message, which was in the Zhangjiang Science and Technology Park, very close to the Da Zhangjiang Campus of the Magic City Complex, and the straight-line distance was only a few kilometers.
In the afternoon of the next day, Xu Qiu took the school sisters and school girls to the Zhangjiang campus by school bus, and then followed the navigation to the Blue River company.
Here is a building with multiple companies settled in. There was a security guard on the first floor watching, and an access card was needed to pass. Xu Qiu had to send a message on WeChat to call out Blue River.
Not long after, Lan He, dressed in casual clothes, appeared at the elevator entrance. After he swiped the access control, he greeted him with a smile on his face and enthusiasm: "Xu Qiu, Chen Wanqing, Han Jiaying, welcome you."
Everyone greeted each other, and Xu Qiu sighed in his heart: "As expected of being the boss, I met at dinner last time, and I can remember the name. Most likely, I did my homework in advance."
A group of four people took the elevator to the third floor. Blue River took the initiative to introduce: "This floor is our Blue River Technology site. Now the team has a total of five people, one PhD and four masters."
"It's quite big." Xu Qiu replied casually, and roughly estimated that the area of ​​one floor here should be close to 500 square meters.
Blue River first led Xu Qiu into a laboratory.
This laboratory is relatively clean, with four glove boxes and two laboratory benches inside.
In the laboratory, five science and engineering men in white coats are working. They are tall and short, but they are generally thin. There is an employee nameplate on the chest of the white coat, which looks decent.
One of them was operating inside the glove box, and two people were watching.
The other two people, one is cutting a flexible substrate of unknown material on the experimental table, and the other is fiddling with stacks of long metal blades on the experimental table. They are the old-fashioned razor blades. 2 cm, about 1 cm wide.
Seeing Lan He brought Xu Qiu and the others in, the five of them nodded in greeting while continuing their work.
Lan River pointed to the person operating in the glove box and introduced: "This is Yang Qin, the only PhD in our company. He graduated from Modu Jiaotong University. The main research field of the previous research was the field effect transistor."
Afterwards, he pointed to the person who was playing with the blade and said: "This is our main research direction now. It is to prepare a large area of ​​organic film by the method of squeegee. The subsequent idea is to integrate other Film-like methods, including spin coating and drip coating, have developed an instrument that puts the material directly in, sets the program, and then can directly prepare the film."
Xu Qiu nodded, and roughly understood Blue River's current thinking. Simply put, it was to build and sell instruments.
There is no big problem in this direction, because the development trend of scientific research instruments is foolish. To put it nicely, it is division of labor and cooperation. If you develop materials, concentrate on developing materials. Our instrument manufacturers will help you solve the problem of device preparation, as long as you pay for it. it is good.
In fact, Xu Qiu also hopes to have an instrument that can integrate various coating processes such as spin coating, squeegee coating, drip coating, spray coating, thermal spin coating, thermal annealing, solvent annealing, etc., as long as the organic materials, solvents, and substrates are placed Go in, the program is designed, press the button, and after "smashing, crackling", the device will come out directly. It would be better if it could be tested automatically.
If such an instrument can be developed, it would not be too much to buy one hundred thousand or several hundred thousand.
Of course, this kind of perfect instrument is just a matter of thinking, but it is actually difficult to realize because there are too many functions.
In the case of "1+1", you only need to consider the compatibility between the two, and in the case of "10+1", you must consider the compatibility between the new function and the other 10 functions, and the complexity will be greatly Promote.
Having said that, as long as it can be made into a simplified version, for example, it only has the function of squeegee, then it can also be used as the first generation instrument and start to sell for money.
In the future, you can slowly upgrade the functions of the instrument.
This is also the mainstream business model. First implement a plausible weak version, and then iterate from generation to generation to continuously strengthen and improve.
If you pursue perfection too much at the beginning, there is a high probability that you will starve yourself to death before reaching perfection.
Just like many games, they were cast out as if they were semi-finished products, and it felt like they were cheating krypton.
In fact, it is cheating Krypton. There is a high probability that the game company has no money and needs to return the blood. If the game improves after making a wave of money, continue to do it well. If the momentum is not right after making a wave of money, it is estimated that you have to prepare to run away. Up.
After all, not every game manufacturer is a goose factory or a pig factory that doesn't cost money.
When Xu Qiu was constantly thinking about it, he suddenly heard the familiar "bang" and "di" sounds in the glove box next to him, which were the sound of the "sun" starting and the sound of the test source meter starting to run.
‘This is testing device performance. 'Xu Qiu couldn't help but walked over to the glove box, wanting to see how their current efficiency is doing. The two white coats who were sitting on the side of the glove box took the initiative to give up their positions to the three people Xu Qiu and Lan He. .
"The device is broken." Chen Wanqing blurted out. She saw that the JV curve in the bright state was not a normal "flat first and then rise" pattern, but chaotic, and the ordinate current value was very low, only ten negative five times. Fang Ma, this is the sign that she is very familiar with the disconnection of the device...
Xu Qiu and Han Jiaying didn't react at the beginning. When they experimented, they didn't encounter many disconnections.
Yang Qin, who was testing the experiment, was a little embarrassed, and Lan He also urged with a little embarrassment: "Let's test another point."
Yang Qin silently changed a point.
Xu Qiu saw the appearance of their device, which was different from the ones in Wei Xingsi's group. Lanhe used a flexible substrate, a long strip of device, about 3 cm long and 1 cm wide, with dozens of pieces on it. Strip-shaped semi-transparent electrodes.
The color of the device is dark blue to purple, which is obviously very uneven. In some places, there is no thin film and almost transparent. In some places, the film is very thick and almost opaque.
Xu Qiu concluded that they used the method of squeegee coating, and the effective layer material is likely to be the standard system PCE10:PCBM.
"Bang", "Drop"...
Soon, the test result of the second point came out.
"The device is short-circuited." Chen Wanqing blurted out again, this time the bright J-V curve is a straight line passing through the origin, and it is also a scene she is familiar with...
In this situation, the senior sister seemed to dream of Bo Yi.
"I'll try another point." Yang Qin finished speaking, and changed another point for testing, and the result was a short circuit again.
Yang Qin weakly explained: "This batch of devices may not be scratched well."
"Then change to a good one, the one tested before will do." Lan He almost laughed at him.
If Xu Qiu and the others did not come to visit, but were customers who came to buy the instrument, they would have gone straight after seeing this result. If the conditions are not optimized, and the instrument that was made is to be bought by someone, it is definitely impossible. of.
Of course, Xu Qiu and the others came here today to make suggestions, and it's nothing to expose the problem.
Yang Qin took out another piece of flexible piece from a nearby lock box and started testing.
The result of this time is that the bright J-V curve is a bit unsmooth, but the overall trend of "flat first and then rise" is not a problem. The final device efficiency is 3.11% and the device area is 0.02 square centimeters.
Yang Qin turned his head and looked at Lan He, and when he saw Lan He nod to him, he began to actively explain: "The system we use is PCE10:PC[70]BM, and the highest efficiency of scratching is about 4%. And the data is very unstable. On the one hand, there are frequent short-circuits and open circuits. On the other hand, the stability is also poor. Even if stored in a nitrogen glove box, the efficiency will basically decay by half after a week."
After Yang Qin finished speaking, everyone turned their eyes to Xu Qiu, as if they wanted to hear his opinions.
Xu Qiu is very familiar with spin coating, but his understanding of squeegee coating is limited to the literature. He only knows that the method of squeegee coating is to first drop the solution on one corner of the substrate, and then move the scraper to spread the solution evenly on the substrate. On the surface of the film, it is mainly used to coat devices with relatively large dimensions, such as 10 cm 10 cm, or even 1 meter 1 meter devices. Because of such a large area, spin coating is definitely not possible.
"Um..." Xu Qiu thought for a moment, and did not rush to a conclusion, but said: "I want to see how your devices are made first."
"Yes," Blue River immediately agreed: "Yang Qin, you take them to visit our laboratory and do a batch of devices on the spot. I'll go back to the office first, and call me if you have anything."
"Okay." Yang Qin came out of the glove box, instructed the other two people on the sidelines to help test the remaining components, and then acted as a tour guide.
The area of ​​this floor is indeed very large: there is a boss’s office; a large office with eight desks now occupying five; a utility room; a public bathroom; Glovebox device laboratory; an equipment processing laboratory, which has a 3D printer, a set of cutting and welding devices, and some basic characterization equipment; and a similar organic laboratory, which has three fume hoods, one of which is ventilated There is an instrument without a casing in the cupboard.
It can be seen that the instruments, equipment, and reagents used by Blue River are relatively new ~EbookFREE.me~ and are relatively expensive, and the investment is estimated to exceed two or three million.
For example, all four glove boxes are imported from beautiful countries, which add up to 100W+.
For another example, the PCE10 they used was also imported from Europe, at more than 4,000 euros per gram, which translates into nearly 30,000 yuan per gram, while the domestic PCE10 purchased from Shencheng Optoelectronics in Wei Xingsi's group is about 10,000 yuan per gram.
"The ability to make money is still fierce." Xu Qiu couldn't help feeling.
Then, by the way, he copied all these instruments, equipment, reagents and so on into the simulation laboratory.
No, I just want to see if the money spent by Blue River is worth it.
