Chapter 321: Opened a door to a new world

After the group meeting, it was already more than three o'clock in the afternoon. Because it was too late, everyone in the organic photovoltaic industry did not choose to go to Zhangjiang for synthesis. They all stayed at the Handan campus.
Han Jiaying was sent to give gifts to several teachers, while Wu Feifei took Mo Wenlin to the Yanyuan Hotel to settle down first. At the same time, she purchased folding beds and N-piece sets of beds online, and also applied for a temporary card for outsiders.
Chen Wanqing continued to prepare battery devices with the IEICS system. She had already done almost the preparation work in the morning, and now directly spin-coated the effective layer. Xu Qiu and Han Jiaying asked her to do a few system devices by the way as a repetitive experiment.
Wu Shengnan had nothing to do, so she concluded her review of perovskite quantum dots.
Xu Qiu started writing articles, two jobs, one system, the target journal AM, and the other target journal JACS. No one in the group has published JACS yet, and I don’t know if he can get the first place. He plans to do both. A short submission format.
Speaking of it, AM does not have Article format articles, but the article length is not very limited. Many articles with about 8 pages and 7 or 8 pictures can be posted. Xu Qiu wants to complain every time he sees this kind of work, and the number of words is all Almost 5000+, this thing is also called?
JACS has strict limits on the length of articles, generally around 4 pages, and articles generally around 7 pages.
The writing structure of Xu Qiu's two works is very simple, and the main selling points are new materials and high efficiency.
The story is also easy to tell. First of all, we optimized the structure of IDT to IDTT based on the IDT-ICIN work of the previous school sisters, obtained IDTT-ICIN, and named it ITIC. Here we introduce the advantages of IDTT over IDT, and then adopt PCE10 The benchmark donor material makes the device efficiency exceed 8%.
Finally, in the conclusion and prospects of the article, I have a foreshadowing, indicating that the light absorption range of ITIC and PCE10 is similar. Later, I plan to further study the wide band gap donor material to match ITIC.
In this way, the second H22: ITIC system can be smoothly introduced, which will break the device efficiency of 10% in one fell swoop, which is equivalent to the world record of efficiency in the field of non-fullerene acceptors.
Picture Xu Qiu intends to put only four of the most critical characterizations, including molecular structure, light absorption spectrum and energy level structure, GIWAXS light source test, J-V characteristic curve and EQE curve.
The light source test will be carried out at the end of this month. Xu Qiu intends to project all the two tasks after the light source is tested at the end of the month. The time is only about two weeks. If you want to write two articles, the difficulty is not small, but fortunately The key efficiency data has been obtained.
Throughout the afternoon, Xu Qiu has been busy structuring the article, and his hands on the keyboard have hardly stopped.
In the evening, Mo Wenlin was settled and returned to Caiyi 216. Xu Qiu took her and Wu Shengnan to carry out cyclic voltammetry experiments to test the energy level structure of ITIC and H22 materials. Both girls Post-doctoral fellows and Ph.Ds who read across different fields are all new in the field of organic photovoltaics and need to start teaching from scratch.
However, the scientific research foundation of the two is there after all, and they learn quickly. After Xu Qiu used ITIC materials for a teaching demonstration, the two cooperated with the operation manual and Xu Qiu's guidance to jointly complete the H22 material test.
After Xu Qiu finished the test, Chen Wanqing's device test results came out.
Among them, the performance of Xu Qiu's two systems has not changed much from the original. Han Jiaying's PBDB-T: ITIC system has an efficiency increase from 9.2% to 9.64%, which is a slight increase. The school girl's PBDB-T system and the original Hxx system Different, the optimal conditions need to be explored slowly.
And the school sister's own system, IEICS two receptor materials combined with H22, the device performance is average, the efficiency is only over 6%, close to the previous IEIC.
However, the combination of these two receptor materials and PCE10 has achieved a breakthrough in performance-the IEICS system has an efficiency of 8.34%, and the system has an efficiency of 9.11%.
"More compatible with PCE10?" Xu Qiu thought of Wu Shengnan's FN-4F system in the simulation laboratory, which is also more compatible with the PCE10 system. It is caused by the shift of light absorption to the near-infrared direction, so he proposed: "Testing Look at the light absorption spectrum and see if it is red-shifted."
"Okay." Chen Wanqing didn't hesitate. He spin-coated a few samples of IEICS individual components with glass slides, tested the light absorption spectrum, got the results quickly, and said excitedly: "Xu Qiu, you guessed it, the light absorption redshift At 650-850 nanometers, it becomes more complementary to PCE10 in light absorption."
Xu Qiu let out a "huh", and then said: "If we can move further to the infrared direction, the light absorption may be more complementary, perhaps the performance can be further improved, and..."
Chen Wanqing smiled and interrupted: "After that, the efficiency is now more than 9%. This time AM can't run."
"That's for sure." Xu Qiuying made a peace, and began to analyze in his heart that the IEICS system of the senior sister is more suitable for chemistry journals, such as JACS and Angew, because the synthesis is more complicated. However, the efficiency is high enough to invest in AM. Fault.
Now AM seems to have become the obsession of the elder sister. In the last IDT-ICIN system work, the elder sister is only one step away from AM. I hope that there will be no more moths this time.
Several materials, such as IEICS, PBDB-T, etc., were developed by Xu Qiu after he went to Kainan University in Tianjin. Because there was no backup in the simulation laboratory, Xu Qiu copied them in and started performance exploration.
On Tuesday morning, Xu Qiu got the result that the system has a maximum efficiency of 9.61%, not breaking 10%, but the school girl’s system is as high as this is another 10% breaking system.
The ITIC system was developed by Xu Qiu, which seems to have opened the door to a new world.
It is foreseeable that the efficiency threshold of non-fullerene systems will gradually be raised in the future, and the days when AM can be published with an efficiency of 6% will be gone forever.
After 8 o'clock, after Xu Qiu and Han Jiaying finished their breakfast together, the school girl mysteriously pulled Xu Qiu downstairs in the bedroom and said, "Brother, wait for me to show you a baby."
Not long after, Han Jiaying reappeared with two handbags printed with HX in her hand.
It looks like a bag for clothes. Xu Qiu has never heard of the brand. He usually doesn't care much about clothes. When he was a child, his parents helped to buy it. When he grows up, he buys it directly online. He doesn't visit physical stores. The concept is limited to the kind of well-known brands, such as Adinike, and what Nima often appears in urban novels.
‘It’s no wonder that the school girl asked me the size of my clothes and shoes last week, but I wanted to buy clothes. "Xu Qiu asked doubtfully: "How come you think of sending me clothes? Is it a holiday today?"
"Brother, you won't forget," Han Jiaying said in surprise: "Your graduating class is going to walk the red carpet this afternoon."
"If it weren't for your reminder, I would have forgotten it," Xu Qiu said with a light sigh, "I didn't come back from the meeting last Friday until this Monday, and then I want to hurry up after writing the two articles and throw them away. Get busy and forget about these trivial things that are not related to scientific research."
"Wait, let's go directly to Caiyi, brother, you can put on this suit," Han Jiaying said coquettishly: "In order to buy this suit, but after spending one month of my pocket money, you can support this month. I."
Xu Qiu touched the school girl's head and said, "No problem."
Early in the morning at nine o'clock, Xu Qiu and Han Jiaying arrived at Caiyi 216, and none of the others came.
Xu Qiu took off his coat directly and put on a four-piece suit of shirt, jacket, pants and leather shoes prepared for him by the school girl. Anyway, he also sits in an air-conditioned office during the day, so he doesn't have to worry about getting dirty during experiments.
After the change, Han Jiaying nodded in satisfaction: "He's pretty handsome."
"Really." Xu Qiu looked into the mirror in the office, changed his formal clothes, and really felt a lot more energetic.
However, Xu Qiu didn't know how a girl defined handsome. Anyway, he looked at other men himself, unless they were obviously crooked, everyone else felt the same and didn't have any special feelings.
Having said that, if there is any special feeling, it is dangerous...
Xu Qiu looked at Han Jiaying and saw that she was still wearing the usual casual outfit, and asked: "Are you school girl, don't you change your clothes?"
"I'll go back after lunch at noon and change it in the bedroom," Han Jiaying explained, "mine is a one-piece dress, it's too much trouble to change."
At half past nine, other friends from the research group came one after another.
Mo Wenlin was the first to arrive. When she saw Xu Qiu, her eyes lit up and said, "Xu Qiu, who are you today?"
Without waiting for Xu Qiu's answer, Han Jiaying declared his sovereignty: "We are going to walk the red carpet together in the afternoon."
Mo Wenlin said "Oh", sat down in her position, her eyes rolled, and she didn't know what she was thinking about~EbookFREE.me~Welfare] Pay attention to the public.. Number [Book Friends Base Camp], read books every day Draw cash/point coins!
After yesterday’s group meeting, Karen Mok’s position was assigned to Wu Shengnan~EbookFREE.me~ which means Chen Wanqing was separated from Xu Qiuzhi. Later, Han Jiaying and Chen Wanqing exchanged positions. Now Xu Qiuhe Mo Wenlin became Han Jiaying in between.
No matter how slow Xu Qiu was, she could still see what the school girl was doing.
So, he talked with the school the way back to the bedroom at night. Xu Qiu felt that after Mo Wenlin came here, he only knew him better, and he still managed it directly. It is normal to be close to him. Moreover, he has also clearly stated his relationship with Han Jiaying with Mo Wenlin, so that the school girl should not worry too much.
However, the school girl said: "Only women know women best. I found out that the school girl has this tendency before. Fortunately, I start quickly..."
Xu Qiu said in surprise: "Senior sister? Really? Why didn't I find out..."
"Brother, you are a big head, I gave you so many opportunities before, if I didn't take the initiative to confess later, hey, let's not talk about this..." Han Jiaying paused and said with a grievance:
"Now that you are on a business trip, you have abducted a girl back. I really don't want to worry about it. You must kill the signs in the cradle. But don't worry, brother, let me take care of everything, you don't have to worry about it."
