I Have a Research Support System

On August 1st, Xu Qiu said hello to his roommate Hao Ren, and then he carried his computer bag on his back and boarded the green leather train home.

Compared to the Spring Festival travel season, the train tickets during the summer vacation are still a little easier to buy. In addition, Xu Qiu bought a student ticket, which can be purchased in advance, so he successfully bought two hard sleeper tickets, both of which he liked. shop.

Senior graduates can buy a student ticket with their student ID card when they go home, and graduate freshmen can also buy a student ticket with their admission letter, but they need to carry their undergraduate student ID card and graduate admission letter with them, which is quite troublesome.

This summer vacation is not much different from the previous few years. Xu Qiu's plan is to stay at home and occasionally go out to visit relatives.

After graduating from college, most of my former high school classmates also graduated from college at the same time. However, this year, even the party was not organized, because most of them were scattered all over the country, turned into screws, and set foot on their respective jobs position, become a glorious worker, and contribute to the development of the country.

After leaving the ivory tower and fading away as a student, there is no such thing as a summer vacation except for professions such as teachers.

In the evening, Xu Qiu ate a homemade "friction" with pork ribs.

"Friction" is a kind of pasta in the north. The main raw materials are potatoes, flour, and minced meat. It is served with chili, salt, butter, pepper powder, dried ginger powder, green onions, and coriander. The taste is smooth but not greasy. , It tastes very cool.

After the meal, Xu Qiu lay happily on the big bed in his room and entered the simulation laboratory.

The efficiency of the previous PCE10:IEICO-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 complete this task during the summer vacation.

So, he summed up the existing optimization methods:

On the one hand, it is the donor material. At present, the main wide bandgap polymer material is in charge of Han Jiaying. From the initial FTAZ and PBDB-T systems, she developed the Hxx series and the PBDB-T derivative system respectively.

The Hxx series, up to H43, has basically been optimized to the end, unless the D unit or the A unit is greatly adjusted, but in that case, it will become a new system, and there is no need to take such a big step for the time being, the main reason is to adjust the molecular structure at will If not, there is a high probability that good results will not be obtained.

For the PBDB-T derivative system, only PBDB-TS is currently available, and its performance is comparable to that of H43. In addition, there are PBDB-TF and PBDB-TSF. The monomers have been purchased from Shencheng Optoelectronics Company, and the last step of polymerization is missing.

On the other hand, it is an ADA-type non-fullerene acceptor material, which is 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 the D unit, there are currently 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 the FN unit in Wu Shengnan’s FNIC, the temporary results show that the longer the conjugate length is, the smaller the band gap width is. , the specific impact on the photoelectric performance is not yet clear, because there are too few samples, Wu Shengnan can be asked to conduct further research in the future;

Third, there are six types of modification of unit A, IT-2F, IT-4F, IT-2Cl, IT-4Cl, IT-DM, and IT-M. IT-4F and IT-M are the most prominent ones. ICIN-2F substituted with difluorine and ICIN-M substituted with monomethyl, while the mono/dichloro substituted system is overall stretchy, 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 is mainly responsible for Chen Wanqing, including IEIC, IEICO, and the derivative IEICO-4F.

After the inventory, Xu Qiu first asked the simulation experimenters to start synthesizing two donors, PBDB-TF and PBDB-TSF, and automatically explored the device performance after the synthesis was completed.

After the order was issued, the simulated experimenters quickly started to re-steam toluene and make nitrogen balloons...

Then, Xu Qiu began to optimize the acceptor material. The path was very clear, which was to combine two effective strategies to obtain a new acceptor material.

However, when he issued an instruction to synthesize materials including IDIC-4F, IDIC-M, etc., he was prompted by the system that "the current instruction cannot be executed, please improve the experimental skills, or increase the authority level."

"It's a bit similar to the feedback from the simulation laboratory when I tried to let the simulation experimenters synthesize IEICO-4F."

After some analysis, Xu Qiu roughly deduced the reason. The polymerization reaction of the two donors is a Stille coupling reaction that he has already mastered, so the simulation experimenter can directly operate it.

For materials such as IEICO-4F, IDIC-4F, and IDIC-M, he has not personally operated some synthesis steps in the middle.

For example, the first few steps of the IEICO-4F reaction involved the introduction of long-chain alkoxy side chains on the thiophene unit. Xu Qiu only knew the reaction process in this step, but did not practice it himself;

The same is true for the IDIC series. He has never practiced the halogenated hydrocarbon reaction used for the introduction of straight-chain alkyl groups.

However, Xu Qiu is not in a hurry, the holiday is very long, so he can wait for the results of the two donor materials first.

If there is no breakthrough in efficiency, he will manually synthesize those several acceptor materials. Anyway, the simulation laboratory I also has a 16-fold acceleration, and it can basically be done in a day or two.

In the early morning of the next day, Xu Qiu was refreshed by the system's news, his whole body shivered, and he woke up immediately.

##

Xu Qiu began to count the harvest.

First of all, 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 appears that combining two effective strategies does not necessarily result in better results.

Secondly, the simulation experiment system III has been newly opened, which allows the consumption of extra points to execute experimental instructions for those who have not mastered the experimental skills.

That is to say, materials such as IEICO-4F and IDIC-4F can now be synthesized by advanced simulation experimenters, but more points are needed.

However, if it is not capped, this is a bit too much...

If you don't pay attention and get a thousand or ten thousand times extra points, the current 160,000 points won't last an hour.

Xu Qiu directly set up a rule, unless he voluntarily modifies this rule, otherwise, if the extra point consumption ratio of the experimental operation exceeds 10 times, it will not be executed by default; between 2 times and 10 times, you need to ask his will; and 2 Times below that can be executed directly by default.

After setting, Xu Qiu began to test.

He instructed the senior simulation experimenters to randomly choose a simple Stille reaction with an extra rate of 0, that is, no extra point consumption;

Then, I tried the synthesis of IDIC-4F, with an extra magnification of 0.3 times, the synthesis of IDIC-M, with an extra magnification of 0.4 times, and the synthesis of IEICO-4F, with an extra magnification of 0.6 times;

Next, the development of ITIC-based field effect transistors has an additional magnification of 6.8 times; the development of controllable nuclear fusion and tokamak devices has an additional magnification of 100,000 times.

Sure enough, the greater the degree of cross-border, the higher the extra magnification.

For example, organic field-effect transistors, that is, OLEDs, have a relatively high correlation with organic photovoltaics. Although Xu Qiu has never been in contact with them before, the extra magnification is not exaggerated. Controlled nuclear fusion requires 100,000 times, one hour per hour. There is no need to consider the consumption of tens of millions of points for the time being.

Finally, after completing the previous advanced task of choosing one of the three, the new advanced task becomes a choice of two, but the task requirements have not changed, it is still the original two.

It seems that these three tasks are packaged, and there is a high probability that there will be some big changes after they are completed.

After all, if these three tasks can be completed, among the new generation of scholars in the field of organic photovoltaics, if not TOP1, at least they will be at the level of TOP3 and TOP5. "Jieqing" and "Qingqian" professors for comparison.

Among the remaining two tasks, the difficulty of publishing ten articles in the first district is relatively small.

Xu Qiu now has four papers in hand, two papers on the way, and a review of non-fullerenes published on ACSEL.

When the Chinese Academy of Sciences releases the new division information of SCI journals at the end of the year, ACSEL will probably be divided into one district. After all, its real-time impact factor has already broken 10.

In addition, there is still some work that has not been sorted out, and it is not difficult to put together three articles in the first district.

The difficulty of the main journal of CNS is relatively high. If you are not a boss, 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 hypocritical about this, as long as he follows the train of thought, further optimizes, and slowly makes a breakthrough, it will be a matter of time before he reaches the top.

He has this confidence.
