I Have a Research Support System

Wei Xingsi smiled unabated, and asked, "What's the matter you came to see me? How is AM's article changed?"

Xu Qiu explained: "The AM reviewer proposed to supplement the color rendering index of the translucent device, but I don't know where there are resources to perform this test."

"Color rendering index, chromaticity meter^ Let me think about it." Wei Xingsi pushed open the door of 218, returned to the office and sat down at the desk, and said after a while: "Let me contact Tang Yunkun, he is from the Department of Physics, he may There is a connection... I originally wanted to find Gong Yuanjiang, but he is too far away, even if it can be tested, it will take a lot of time."

After all, Wei Xingsi dialed Tang Yunkun directly, and the two started chatting in Moduhua.

Xu Qiu couldn't quite understand their chat, so he found a chair and sat down to wait. He picked up a few new articles and browsed them, and saw a small article about ITIC published on JMCA.

The popularity of the ITIC series of non-fullerene acceptors has even overwhelmed the PCBM fullerene acceptors that have dominated the field of organic photovoltaics for more than ten years.

Speaking of Tang Yunkun, he helped the group purchase a TRPL instrument with funds.

Later, Wei Xingsi reciprocated and brought him together to publish a review article on non-fullerene acceptors on ACSEL.

However, there was less cooperation between the two parties later on.

The main reason is that Tang Yunkun's side is almost engaged in pure theoretical research, and rarely does experiments. Most of the time, it is purely based on simulation calculations and other means for research, which is relatively more basic science, which is different from Wei Xingsi's side, which is biased towards applied science. The research direction is somewhat biased,

In addition, it is also because Wei Xingsi has found other collaborators in theoretical research, and they are all biased towards application and are more compatible, so the two parties gradually drifted apart.

Like Feng Shengdong in Sweden, they have laser equipment that can test TAS, TRPL, THz, etc.;

Ronlad in Finland, they also have CELIV, TOF and other means.

A few minutes later, Wei Xingsi hung up the phone and said to Xu Qiu:

"It's done. Tang Yunkun said that he helped to contact a teacher in the physics department. The other party's laboratory is in Room 307 on the third floor of the Henglong Physics Building on the Handan Campus. You can go directly with the samples tomorrow morning and just report Tang Yunkun's name." Testing, it is said that it is not difficult to test, just take the finished device with you.”

"Okay," Xu Qiu nodded, and read the address silently: "Room 307 on the third floor of the Henglong Physics Building..."

"By the way, remember to update this "Joule" article on the website of our research group. In addition, please contact the departments to help them promote it." Wei Xingsi said with a smile:

"With this "Joule", I will have more confidence in the industry conference we organized in December. It would be great if the other "Natural·Energy" can come out soon."

Without waiting for Xu Qiu to answer, Wei Xingsi continued on his own and said, "I'll send this review to others later, and I'll call Gong Yuanjiang by the way."

"Then I'll go to work first." Xu Qiu stood up and said goodbye.

Teacher Wei probably wants to blow a wave of "Joule" published by the research group to his friends, so Xu Qiu won't join in the fun.

On Friday morning, Xu Qiu went to the Hang Lung Physics Building with the semi-transparent battery device that had been kept before as a sample.

The Hang Lung Physics Building is also an old building. It has been built for decades, so the outer walls are a bit dilapidated, but the inside is relatively clean, and there is no smell of organic laboratory solvents.

Arriving at Room 307, Xu Qiu reported Tang Yunkun's name, and a boy who looked like a graduate student received him and then helped him test the samples.

Xu Qiu watched from the side, and the whole testing process didn't seem very difficult, just put the sample on it with tweezers, run the instrument, control it with a computer, and the data will be available.

Each sample was tested three times, a total of 6 samples, and it took less than half an hour in total. Finally, the data was a group of coordinates and a standard chromaticity diagram.

The general principle of evaluating the color rendering index is to fold the transmission spectrum of the sample with the AM1.5 spectrum to obtain the perceptual transmission lighting result data under sunlight, and then perform color matching function coupling with the CIE-1931-2 standard observer , so as to obtain the corresponding horizontal and vertical coordinate points, and finally mark the coordinates of each sample in the standard chromaticity diagram.

In this AM article by Xu Qiu, in order to pursue the workload, he made thin-layer electrode devices ranging from 10 nanometers to 20 nanometers, so a total of six sets of coordinates were obtained.

The results show that the thinner the thin-layer metal electrodes of the translucent device, the closer the obtained chromaticity coordinates are to the center of the image, that is, the closer the transmitted light is to normal sunlight.

In the evening, Xu Qiu added a small class, corrected AM's article, wrote the reply document for review comments, and handed it over to Wei Xingsi for revision and then sent it back to the editor.

On Sunday, the simulation experiment system has developed new Y4 and Y5 materials based on the previous Y3.

Now Xu Qiu has a series of materials from Y1 to Y5, among which:

Y1 is a system of NT and monothiophene T, the central D unit is a five-membered fused ring, and the A units on both sides are ICIN, which has poor performance.

Y2 is a system of NT and TT, the central D unit is a seven-membered fused ring, and the A units on both sides are ICIN. Combined with the donor J4, the highest device efficiency can reach 13.3%.

Y3 is the product of Y2 through side chain regulation, and the conjugated structure of D and A units has not changed compared with Y2. Combined with the donor J4, the highest device efficiency can reach 14.2%.

Y4 is based on Y3, with the ICIN end group changed to ICIN-2F. Combined with donor J2, the efficiency is 14.3%, and combined with donor J4, the efficiency is 14.6%.

Y5 is based on Y3, changing the ICIN end group to ICIN-2Cl structure. Combined with donor J2, the efficiency is 14.7%, combined with donor J4, the efficiency is 14.8%, combined with the donor PTQ1, the efficiency is 13.8%, combined with other even the first generation of wide bandgap donors, such as H1, FTAZ, PBDB-T And so on, the device efficiency can easily break 12%.

This is the synergistic effect of different systems in the same field. Once a breakthrough is made in a certain place, the experience gained from other fields in the early stage can be spread over immediately.

And if there is no previous preliminary work, even if you get Y1, you still have to work hard to get Y4 and Y5.

The current highest efficiency is 14.8%, which is only one step away from 15%.

Monday morning.

When Xu Qiu was eating breakfast with his school girl in the cafeteria, he suddenly froze for a moment.

He found that the system was advanced, and immediately realized that the amended AM articles should have been accepted last week, and the number of articles in SCI District 1 reached ten.

Sure enough, it didn't take long for him to receive an email forwarded by Wei Xingsi, and Xu Qiu directly shared the news of "received AM articles" with the school girl beside him.

"Wow, senior, that's amazing~" Han Jiaying bit the straw of soy milk and said, "If I remember correctly, this should be the tenth SCI District 1 article by senior."

"Yeah..." Xu Qiu was a little surprised: "How do you remember it so clearly?"

"That's necessary, I still remember the specific journal." Han Jiaying smiled proudly: "Three AM, two AEM, one ACSEL, one Angew, one NC, one Joule ("Joule") , Why is there one article missing... Well, it’s four AM articles, and I posted another one just now, brother, I’m right.”

"That's right." Xu Qiu pampered Xuemei's head.

"What about me, how many district one articles did I post?" Han Jiaying asked.

"This..." Xu Qiu hesitated and couldn't answer, so he had to start guessing: "Six? Or seven?"

"Hmph!" Han Jiaying put her hands on her hips, making a huffy look.

Back at Material 1 216, Xu Qiu spent half a day trying to appease Han Jiaying, then found a corner and carefully checked the system messages.

##

Two of the previous tasks of choosing one of the three have been completed, and only the last task is left, which is to publish an article in the CNS main journals of "Nature", "Science" and "Cell".

It's just that the reward for this mission is not listed, and I don't know what it will be?

Publishing an article in the main journal of CNS, although it is difficult for the not-so-popular field of organic photovoltaics, but Xu Qiu now has a new Y-series material in his hand, so he is not in a hurry, and there is still a high probability that it can be completed if he works hard.

In addition, Xu Qiu now uses Simulation Lab III more, that is, senior simulation experimenters. Now the number of people has changed from 1 to 2, and the efficiency of exploration has directly increased by 100%. Of course, the number of points consumed will also increase. Then double it.

Fortunately, Xu Qiu was relatively restrained before, and accumulated a lot of points. In addition, the points for this system upgrade weekly task have doubled, so now he doesn't have to worry too much about point consumption.

As long as you don't cross domains, basically you can't spend all the points.
