Chapter 440: AM reception, the efficiency is close to 15%! The advanced task is complete!

Wei Xingsi smiled undiminished, and asked, "Is there anything you came to find me? How's the AM article changed?"
Xu Qiu explained: "AM's reviewer proposed to supplement the color rendering index of translucent devices, but I don't know where there are resources for this test."
"Color rendering index, colorimeter^ let me think about it." Wei Xingsi pushed open the door of 218, returned to the office table and sat down, and said after a while: "Let me contact Tang Yunkun. He is from the Physics Department. There is a way...I wanted to find Gong Yuanjiang, but his side is too far away. Even if it can be measured, it will take a lot of time."
After all, Wei Xingsi directly dialed Tang Yunkun's phone, and the two opened the chat mode of Moduhua.
Xu Qiu didn't quite understand the content of their chats, so he found a chair and sat down and waited. He picked up a few new articles and browsed them, and saw an ITIC-related article published on JMCA.
The popularity of the current ITIC series of non-fullerene receptors has even surpassed the PCBM fullerene receptors that have dominated the organic photovoltaic field for more than a decade.
Speaking of Tang Yunkun, he used to help the team buy a TRPL instrument with funds.
Later, Wei Xingsili went back and forth and took him together to publish a review article on non-fullerene receptors on ACSEL.
However, there was less cooperation between the two parties.
The main reason is that Tang Yunkun does almost pure theoretical research, and rarely does experiments. Most of the time, he relies purely on simulation calculations and other means to conduct research, and he is relatively more inclined to basic science, which is similar to Wei Xingsi’s preference to applied science. The research direction is somewhat deviated,
In addition, it was also because Wei Xingsi found collaborators in other theoretical researches, and they were all more application-oriented and more compatible, so the two sides gradually moved away.
Like Feng Shengdong from Sweden, they have laser equipment that can test TAS, TRPL, THz, etc.;
In Finland, they also have CELIV, TOF and other methods.
A few minutes later, Wei Xingsi hung up the phone and said to Xu Qiu:
"It's done. Tang Yunkun said that he helped 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 bring the sample to Tang Yunkun's name tomorrow morning. It’s said that it’s not difficult to test, just take the finished device directly."
"Okay," Xu Qiu nodded, and silently read the address: "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, the department also contacted and asked them to help promote the publicity." Wei Xingsi said with a smile:
"With this "Joule" and the industry conference we organized in December, I will feel more confident. If only another "Nature·Energy" could come out soon, it would be great."
Without waiting for Xu Qiu to answer, Wei Xingsi continued to say to himself: "I will post this review to others and give Gong Yuanjiang a call by the way."
"Then I'll go ahead." Xu Qiu got up and resigned.
Teacher Wei guessed that he was going to blow a wave of "Joule" published by the research group to his friends, and Xu Qiu would not join in the excitement.
On Friday morning, Xu Qiu took the translucent battery device that was saved before as a sample and went to the Henglong Physics Building.
The Hang Lung Physics Building is also an old building. It has been built for decades, so the exterior walls are a bit tattered, but the inside is relatively tidy, and there is no smell of organic laboratory solvents.
Arriving in room 307, Xu Qiubao reported Tang Yunkun's name, and a boy who looked like a graduate student received him and then helped him test samples.
Xu Qiu was watching. The whole test process did not seem to be difficult. Just put the sample on with tweezers, the instrument was operated, the computer was manipulated, and the data was ready.
The test was repeated three times for each sample, a total of 6 samples, which took less than half an hour in total, and the final data was a set 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 result data of the perceptual transmission illumination under sunlight, and then to perform the 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.
Xu Qiu’s AM article originally made thin-layer electrode devices ranging from 10 nanometers to 20 nanometers in order to pursue the workload, so a total of six sets of coordinates were obtained.
The results show that the thinner the thin metal electrode 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 to correct the AM article, write the review comments and reply documents, and send it to Wei Xingsi for revision and send it back to the editor.
On Sunday, the simulation experiment system has developed new Y4 and Y5 materials based on the previous Y3.
Xu Qiu now has a series of materials from Y1 to Y5, including:
Y1 is a system of NT and monothiophene T. The D unit in the center 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 D unit in the center is a seven-membered fused ring, and the A units on both sides are ICIN. Combined with 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 is unchanged compared to Y2. Combined with donor J4, the highest device efficiency can reach 14.2%.
Y4 is based on Y3, the ICIN end group is changed to ICIN-2F structure. When combined with donor J2, the efficiency is 14.3%, and when combined with donor J4, the efficiency is 14.6%.
Y5 is based on Y3, the ICIN end group is changed to ICIN-2Cl structure. Combined with donor J2, the efficiency is 14.7%, combined with donor J4, the efficiency is 14.8%, combined with donor PTQ1, the efficiency is 13.8%, combined with other even the first generation wide band gap donors, such as H1, FTAZ, PBDB-T Like, the device efficiency can easily break 12%.
This is the linkage effect of different systems in the same field. Once a breakthrough is made in one place, the previous experience gained from other fields can be immediately spread.
And if there is no previous preliminary work, even if you get Y1, you will have to spend a lot of hard work to get Y4 and Y5.
The current maximum efficiency is 14.8%, which is only one step away from 15%.
Monday morning.
When Xu Qiu was eating breakfast with her school girl in the cafeteria, she was taken aback.
He found that the system was advanced, and immediately realized that the AM article that was revised last week was accepted, and the number of articles in the SCI area reached ten.
Sure enough, it didn't take long for him to receive the email forwarded by Wei Xingsi, and Xu Qiu directly shared the news of "AM article reception" with the school girl beside him.
"Wow, brother, that's amazing~" Han Jiaying bit the straw of soy milk and said, "If I remember correctly, this should be the tenth SCI article of the brother."
"Yeah..." Xu Qiu was a little surprised: "Why do you remember so clearly."
"That is necessary, I still remember the specific journal." Han Jiaying smiled triumphantly: "Three AM, two AEM, one ACSEL, one Angew, one NC, one Joule ("Joule") , Why is one missing...well, it's only four AM articles. I just posted another one. Brother, I'm right."
"That's right." Xu Qiu petted and touched the school girl's head.
"What about me, how many articles have I posted?" Han Jiaying asked.
"This..." Xu Qiu hesitated to answer, so he began to guess: "Six articles? Or seven articles?"
"Huh!" Han Jiaying made a bulging look with her hands on her hips.
Returning to Caiyi 216, Xu Qiu spent a long time pacifying Han Jiaying, then found a corner and carefully checked the system messages.

Before the integration of the three tasks, UU Reading www.uukanshu.com has completed two, and only the last task is left, to publish a CNS main journal 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?
It is difficult to publish a CNS main journal. Although it is difficult for the less popular field of organic photovoltaics, Xu Qiu now has new Y series materials in his hands. He is not very panicked. Working hard still has a high probability of being completed.
In addition, Xu Qiu now uses Simulation Lab III, which is a high-level simulation experimenter. Now the number has changed from one to two. The efficiency of exploration is directly increased by 100%, and of course the number of points consumed will also be Then doubled.
Fortunately, Xu Qiu was more restrained before and accumulated a lot of points. Coupled with the doubling of points for the weekly tasks of the system upgrade, now he doesn't have to worry too much about points consumption.
As long as you don't cross fields, you can't spend your points.
