Chapter 348: The advanced task is complete! New features are open!

On August 1, Xu Qiu greeted her roommate Hao Ren, and then carried her computer bag on her own and embarked on the green train home.
Compared with the Spring Festival travel season, the train tickets during the summer vacation are slightly better to buy. In addition, Xu Qiu bought student tickets, which can be purchased in advance. Therefore, he successfully bought two hard sleeper tickets, both of which he liked. shop.
Senior students can buy student tickets once with their student ID when they go home, and new graduate students can buy once with the admission notice. Just need to carry the undergraduate student ID and postgraduate admission notice with them, which is quite troublesome.
This summer vacation is not much different from the previous years. Xu Qiu's plan is to stay at home and occasionally go out to walk with relatives.
After graduating from university, the previous high school classmates basically graduated simultaneously. However, this year's party was not even organized because most people were scattered across the country, turned into screws, and embarked on their respective jobs. Position, become an honorable hitman, and contribute to the development of the country.
After leaving the ivory tower and losing the identity of a student, there is no more summer vacation except for professions such as teachers.
In the evening, Xu Qiu had a home-made "friction rub" with pork ribs.
"Friction rub" is a kind of pasta in the north. The main raw materials are potatoes, flour, mashed meat, with chili, salt, butter, pepper powder, dried powder, green onions, and coriander. The taste is smooth and not greasy. , It tastes very refreshing.
After the meal, Xu Qiu lay on the big bed in his room and entered the simulation laboratory.
The efficiency of the previous PCE10:-4F system has been optimized to 12.44%, which is only one step away from the 12.71% required to complete the advanced task. He plans to take advantage of the summer vacation to complete this task.
So he summarized the existing optimization methods:
On the one hand, it is the donor material. At present, the main wide band gap polymer material is in charge of Han Jiaying. She developed the Hxx series and PBDB-T derivative system from the initial FTAZ and PBDB-T systems, respectively.
The Hxx series, up to H43, have basically been optimized to the end. Unless the D unit or A unit is greatly adjusted, but in that case, it will become a new system. There is no need to step so much for the time being. The main reason is to adjust the molecular structure at will If so, there is a high probability that good results will not be obtained.
For the PBDB-T derivative system, only PBDB-TS is currently available. Its performance is equivalent to H43. In addition, there are PBDB-TF and PBDB-TSF. The monomers have been purchased from Shencheng Optoelectronics Co., Ltd., just before the final step of polymerization.
On the other hand, it is an ADA-type non-fullerene acceptor material, mainly based on the original IDT-ICIN and the current benchmark material ITIC. There are currently four optimization paths.
First, the side chain modification of D unit, currently there are three types of ITIC-Th, m-ITIC, and IDIC, all of which perform well.
Second, the conjugate length of the main chain of the D unit is modified, from the original IDT to the IDTT in ITIC, and later the FN unit in Wu Shengnan FNIC. As a temporary result, the longer the conjugate length, the smaller the band gap. , The specific impact on the photoelectric performance is not clear, because there are too few samples, and Wu Shengnan can conduct further research in the future;
Third, the modification of A unit, there are six kinds of IT-2F, IT-4F, IT-2Cl, IT-4Cl, IT-DM, IT-M, IT-4F and IT-M are more outstanding, corresponding The ICIN-2F which is substituted by fluorine and the ICIN-M which is substituted by monomethyl are used, while the mono/dichloro substituted system is used to pull the hips as a whole, but it is not ruled out that it will be effective in other systems;
Fourth, imitating the A-π-D-π-A structure of IDTBR, which is mainly in charge of Chen Wanqing, with IEIC, and derivative-4F.
After the inventory, Xu Qiu first asked the simulation experimenter to start to synthesize two kinds of donors, PBDB-TF and PBDB-TSF, and automatically explore the device performance after the synthesis was completed.
The instruction was issued, and the simulation experimenters quickly started to re-evaporate toluene and make nitrogen balls...
Next, Xu Qiu started to optimize the receptor material. The path was very clear, which was to combine two effective strategies to obtain a new receptor material.
However, when he gave instructions to synthesize materials including IDIC-4F, IDIC-M, etc., he was prompted by the system that "the current instruction cannot be executed, please upgrade the experimental skills, or increase the authority level."
"It's kind of similar to the feedback from the simulation lab when I tried to get the simulation experimenter to synthesize -4F."
Xu Qiu analyzed it and roughly deduced the reason. The polymerization reaction of the two donors was the Stille coupling reaction that he had already mastered, so the simulation experimenter could directly operate it.
And for the materials of -4F, IDIC-4F, and IDIC-M, he has not personally manipulated some of the synthesis steps in the middle.
For example, the first few steps of the reaction of -4F involve the introduction of long-chain alkoxy side chains on the thiophene unit. In this step, Xu Qiu only knows the reaction process, but has not personally practiced it;
The IDIC series has the same principle, introducing linear alkyl groups and using halogenated hydrocarbon reactions, which he has not actually done.
However, Xu Qiu is not in a hurry. The holiday is very long. You can wait for the results of the two donor materials first.
If there is no breakthrough in efficiency, he will manually synthesize the several receptor materials. Anyway, the simulation laboratory I has a 16-fold acceleration, which can basically be done in a day or two.
Early in the morning of the next day, Xu Qiu was swiped by the system's news, and his whole body was stunned, and he suddenly woke up.
[It was detected that the efficiency of the organic solar cell device prepared by the host reached 12.88%, which has broken the world record of photoelectric conversion efficiency in the field of organic solar cells (12.21%), and the increase rate exceeded 0.5%.

Xu Qiu began to count the harvest.
First, the device efficiency has broken through to 12.88%.
Xu Qiu checked the detailed data. The system is PBDB-TF: IT-4F, and the performance of the other PBDB-TSF is not as good as PBDB-TF, but it is not much worse. The highest efficiency is 12.67%.
It seems that after combining two effective strategies, better results may not always be obtained.
Secondly, a new simulation experiment system III has been opened, allowing additional points to be spent to execute experimental instructions that are not proficient in experimental skills.
In other words, materials like -4F and IDIC-4F can now be synthesized by advanced simulation experimenters, but they require more points.
However, if it is not capped, it would be a bit too much...
If you don’t pay attention and get a thousand or tens of thousands of extra points, the 160,000 points will not be able to withstand an hour.
Xu Qiu directly set a rule, unless he actively modify this rule, otherwise if the extra points consumption rate of the experiment operation exceeds 10 times, it will not be executed by default; between 2 times and 10 times, he needs to ask his wishes; and 2 Below times, it can be executed directly by default.
After setting it up, Xu Qiu started testing.
He instructed the senior simulation experimenters to choose a simple Stille reaction at random, with an extra multiplier of 0, which means no extra points consumption is required;
Subsequently, I tried the synthesis of IDIC-4F, the extra magnification was 0.3 times, the synthesis of IDIC-M, the extra magnification was 0.4 times, and the synthesis of -4F, the extra magnification was 0.6 times;
Next, the development of field-effect transistors based on ITIC has an extra magnification of 6.8 times; the development of controllable nuclear fusion and tokmak devices has an extra magnification of 100,000.
Sure enough, the greater the degree of crossover, the higher the additional magnification.
For example, organic field-effect transistors, or OLEDs, have a relatively high correlation with organic photovoltaics. Although Xu Qiu has not been in touch before, the additional magnification is not exaggerated, and controlled nuclear fusion requires 100,000 times, one hour per hour. Ten million points consumption, for the time being, no need to consider.
Finally, after completing the advanced task of choosing one of the three before, the new advanced task is changed to one of the two, but the task requirements have not changed, and the original two are still the same.
It seems that these three tasks are packaged, and there will be some major changes when they are completed with a high probability.
After all, if these three tasks can be completed, among the new generation of scholars in the field of organic photovoltaics, even if they are not TOP1, they are at least TOP3 and TOP5, and the target of this comparison is not the student group~EbookFREE.me~ but Compare with the professors of "Yangtze River", "Jieqing" and "Qingqian".
In the remaining two tasks, the difficulty of publishing ten articles in one area is relatively small.
Xu Qiu now has four in his hand, two on the road, and a non-fullerene review published on ACSEL.
By the end of the year when the Chinese Academy of Sciences releases new SCI journal zoning information, ACSEL will most likely be divided into one area. After all, its real-time impact factor has now broken 10.
In addition, there are still some unorganized work, and it is not difficult to put together three more one-section articles.
The difficulty of the CNS main journal is relatively high. If you are not a big man, most research groups want to publish an article of this level, and it takes about two years to prepare on average.
Of course, Xu Qiu is not very fictitious about this. As long as he follows his ideas, further optimizes, and slowly achieves a breakthrough, it will be sooner or later to reach the top.
He has this confidence.
