Chapter 206: The materials you sell are developed by me

"I have a scientific research support system ( to find the latest chapter!
Early the next morning, Xu Qiu entered the simulation laboratory II to test the results.
The simulation experimenters have completed several basic characterizations of the three products.
However, it only completes the experimental operation and cannot perform data analysis.
Xu Qiu had no choice but to go out in person. He took the raw data and analyzed the spectrum by himself.
It can be determined that the three main products are all diamine substitutes of perylenetetracarboxylic dianhydride, and the purity of the sample is above 99%.
At the same time, simulation experimenters are still working on device preparation, testing and optimization.
Yesterday, Xu Qiu gave it a fuzzy instruction, which only provides initial conditions and prioritized optimization directions.
Initial conditions He found the conditions in a literature as a reference, and the priority of the optimization direction, from large to small, were speed, thermal spin coating temperature, post annealing temperature, solvent additives, solvent type, solution concentration, and DA blending ratio. ...
It is a bit similar to what he did when optimizing the PCE11 system before, but now he does not need to do it himself, and directly allows the simulation experimenter to imitate his ideas for optimization.
The specific optimization mechanism is currently unclear and remains to be seen.
Of course, the simulation experimenter also supports precise settings, which is similar to programming, and the specific optimization route is clearly written, such as:
ifPCE (small speed)
then speed +=100;
Else speed -=100;
However, this method is not very feasible in the initial stage of the experiment, because there are too many variables, and when optimized to the later stage with fewer variables, you can try to use it.
The work efficiency of simulation experimenters is very high. On the one hand, they are tireless, and on the other hand, they can work in multiple threads and conduct multiple experiments at the same time.
Therefore, the first batch of data on photovoltaic performance has been produced.
There are two kinds of donor materials, PCE10 and PCE11, and the acceptor materials are three simple PDI molecules synthesized yesterday.
The highest efficiency based on the PCE10 system is currently over 3%, while the PCE11 system is only a few tenths, less than 1%.
The efficiency data of the PCE10 system does not look high, but Xu Qiu expected it.
The system based on PCE10 and simple PDI in the existing literature has the highest efficiency around 4%.
He can now have 3%, which is considered to be a reproduced literature data.
At present, there are not many systems where the efficiency of the PDI series can reach 6%-8%, and the PDI molecules they use are all improved products based on simple PDI molecules.
The modification of simple PDI molecules is also the focus of Xu Qiu's next work.
As for the PCE11 system, he can roughly guess the reason for the low efficiency.
The crystallinity of the two is too strong, which is not conducive to the formation of a good blend morphology, and poor device performance is normal.
It's just that he didn't expect it to be so bad.
Xu Qiu originally thought that if there is about 1, 2%, optimization can reach 3 or 4%, maybe a small article can be produced, but now its base is too low, there is no need to continue optimization for the time being.
So, he cancelled the instruction of the simulation experimenter to optimize the PCE11 system and let it focus on the PCE10 system.
Afterwards, if you have modified PDI materials, it will not be too late to restart.
...
At 8:45 in the morning, Xu Qiu came to the school bus meeting point.
There were not many students who took the school bus during the holidays. There were only three people besides him, so there was no queue.
A few minutes later, Han Jiaying and Chen Wanqing also came over one after another. The school girl seemed to be awake, but the school girl was full of energy.
The three greeted each other and talked about the arrangements for today's experiment.
After a while, the driver's master opened the door, and under the direction of the security brother, everyone swiped their cards to board the car.
Because of the small number of people, there are a lot of vacant seats in the front row. Chen Wanqing sat in the second row, while Xu Qiu and Han Jiaying were seated in the fourth row.
After she was seated, the school girl took out her mobile phone, plugged in the earphone cable, and handed Xu Qiu a earphone. He took it naturally and put it in her ear.
Soon, a gentle English song came to my ears.
"I'll sleep for a while, and call me when I arrive."
"Ok."
Xu Qiu had a good rest yesterday, and now she is very energetic, so she doesn't close her eyes and rest.
He thought of buying polymer donors, so he turned on his phone and found the product catalog files previously sent to him by several sales companies.
Common polymer donors are such as PCE10, PTB7, P3TEA, PDBT-T1, PDPP2T, etc. Most of them are narrow bandgap polymers based on traditional fullerene systems.
‘The average price is around 1500 for 100 mg, and the lowest price is 100 or 200 mg. If you buy 100 mg of each, it will add up to tens of thousands. ’
‘But I don’t actually need a lot of dosage. As long as there are about 10 mg, there are endless materials in the simulation laboratory. ’
‘Or ask them for some samples, and I don’t know if they will give it. ’
‘Before the election, the company that cooperates a lot, ask the company in Shenzhen. ’
"Hello, can you send a new product catalog?" Xu Qiu sent a message.
A few minutes later, the salesperson responded:
"I'm here."
"[The latest product catalog in February.PDF]" Xu Qiu accepted the document, but before he could read it, he received another message:
"Our company has recently developed a batch of PCE11 materials. Now the efficiency can reach 9.5% or more after blending with PC[70]BM. Is your research group interested in buying some?"
"150001 g~EbookFREE.me~ mg, 4000200 mg, 2500100 mg."
"This is a job recently published on AM. At present, there should be only one of our companies producing this product in China." Then I sent a screenshot with the article title and molecular structure information.
Xu Qiu was shocked. Isn't this his material? It was put on the product catalog by the Optoelectronics company so quickly, and it was sold so dark.
Sure enough, keeping up with the times can make money.
"The materials you sell were developed by me. At that time, the monomers were bought from your side..." Xu Qiu replied.
The other party returned an emoticon pack of "eating whales", and then said:
"I saw the historical record, it's really you."
"Will it be convenient to talk about material synthesis and device manufacturing process?"
Xu Qiu thought for a while, and calmly replied: "Yes, our research group is currently expanding the research direction. Can you send us samples of several donor materials? If it works, we will buy them in bulk." It’s also true that if you try it out in a simulation laboratory, you still have to buy materials if you switch to experimenting in reality.
"No problem, please report me the name of the material."
"PTB7, P3TEA, PDBT-T1, PDPP2T..."
"Okay, I recorded it, and I will arrange the delivery for you immediately. The address has not changed."
"The address has not changed."
Seeing that the other party was so polite, Xu Qiu didn't have any secrets, and told the other party about the PCE11 material synthesis and device preparation.
Unexpectedly, the material problem can be solved so easily, this time there is no need to apply for funding with Teacher Wei.
