I Have a Research Support System

Previously, Xu Qiu looked forward to the future research direction, with a high probability of working towards non-fullerene systems.

However, there is no rush to change direction.

At this stage, we still need to study around PBT4T and its four derivatives.

After all, he is currently a senior, a student who has just chosen a direct Ph.D., and has a long time to do scientific research in the future.

When doing scientific research, most of the time, what is emphasized is the integrity and coherence of a system, and the kind of research that is one hammer and one stick is more taboo.

This point is more obvious in the large research group.

Especially for pioneers in a field, tutors will require their students to make a complete and coherent system in their usual scientific research work and final writing of graduation thesis.

After all, the real scientific research life is not like a novel. You can cross industries casually, build rockets today, and nuclear fusion tomorrow.

Interlaced like a mountain.

Even if they are scientific research experts, most of them are constantly accumulating, digging, and breaking through several sub-categories in a large field.

The reason is that now the field of scientific research has tended to the Red Sea, and most of the dividends of scientific research have been almost divided by scientists in the early years.

Like the era of Newton and Einstein, the scientific research building was initially established, and any discovery could be recorded in the annals of history.

It is different now, the exploration of scientific research is approaching the boundaries of human cognition.

If you want to make a big breakthrough, you not only need enough scientific research talents, but also spend a lot of time on trial and error.

This is somewhat similar to the development of social productivity.

When the productivity develops to a certain level and enters the bottleneck period, it is necessary to popularize education for all and improve the comprehensive quality of all human beings in order to continue to make breakthroughs.

...

Next, Xu Qiu began to think about arranging a research direction for Han Jiaying.

At present, his article based on P2FBT4T-2OD has been submitted and voted for AM.

The leftovers are:

PBT4T, the original molecule, can publish an article.

The P2FBT4T series, four molecules with different side chains, can be compared with each other, and an article is published.

These two articles still need to be submitted quickly, otherwise they may be preempted by other research groups.

P2FBT4T-2OD material, to study the dependence of its crystallization properties on temperature, this article has been booked by the senior sister.

After thinking about the system based on PBT4T, there are no remaining research directions.

The first two tasks above cannot be directly given to the juniors, because they have basically been completed, and the main experimenter is Xu Qiu.

It would be too much to send her a piece of work.

So, what about other directions?

At the beginning, he also designed the directions of PBT2T, 3T, and 5T.

However, would it be too difficult for her to hand over this direction to the school girl?

Before, just adjusting a side chain would have a great impact on the properties of the molecule. Xu Qiu encountered many difficulties during the experiment.

After untold hardships, the efficiency was increased from 4% to more than 10%.

If the main chain is directly changed now, more problems will definitely be encountered, and the obtained molecules may not be suitable as photovoltaic materials.

As for the simple direction, it is easy to think of, you can imitate the way of the senior sister:

Ternary blend effective layer, ternary conjugated polymer...

Or walk through other side doors, flexible substrates, perovskite transport layers, translucent electrodes, etc...

After thinking for a while, Xu Qiu decided to put two paths in front of her and let her choose.

He found Han Jiaying and said:

"About your project, I have two directions here, one is more difficult and the other is relatively simple..."

Before she finished speaking, Han Jiaying made a choice without hesitation:

"I choose the difficult one!"

"Don't you want to listen to the content?" Xu Qiu asked curiously.

"It's the same to make a choice first and then listen." Han Jiaying said:

"I also hope that in the future, I can post good articles like AM like my brother."

After a moment of silence, Xu Qiu said:

"Then you should study the systems of PBT2T, 3T, and 5T. You can directly use the system with two fluorine atoms, 2F, which may have better performance.

When I finish my work next week, you and I will go to Zhangjiang to study synthesis. "

"Okay." Han Jiaying nodded.

Xu Qiu originally planned to say "we are different", but he stopped when the words came to his lips.

What's the difference?

They are young people with dreams.

In her body, Xu Qiu saw his own shadow, just like himself when he first entered the scientific research circle.

This is good or bad, if you don't choose the right direction, you may end up in a bad situation.

At the beginning, he was also full of pride, thinking about changing the world, but later he realized how difficult it was.

How insignificant personal power is in the face of the torrent of this era.

Even if he has a system that is not a big or small thing, even if he can really change the world in the future.

In this process, it is also destined to move forward steadily step by step.

Xu Qiu thought of Chen Wanqing again, the leader on his scientific research path.

Thinking of my senior sister's self-knowledge, although her dream is to write an AM, she knows that her own ability is not enough, so she desperately writes in the second district.

In the future, look for an opportunity to see if I can fulfill her dream.

After all, there is still more than a year left. If all goes well, she will graduate soon, and I don't know what path she will choose in the future.

...

Monday group meeting.

Wu Feifei previously dropped an article on ammonium chloride additives, which was posted on CM, and has not yet returned comments, and now she has started a new job.

For traditional lead-based perovskite materials, lead iodide is used, but she chose a pseudohalogen lead compound, lead thiocyanide, as an additive.

That is, in traditional MAPbI3, a certain proportion of Pb(SCN)2 is added to form a structure like MAPbIx(SCN)3-x.

Preliminary progress has been made, and the efficiency has exceeded the standard sample.

Now, the highest efficiency of the perovskite system has exceeded 20%, and it has become an emerging hot field.

Moreover, after Wei Xingsi returned to China, this field had just started, and he was one of the first people to enter this field.

For an emerging field with unlimited potential, there are many research directions that can be explored and many articles can be produced.

Wu Feifei felt a little standing on the wind.

Of course, her own strength is also there. The superposition of strength and luck, naturally the article is published smoothly.

If it wasn't for Xu Qiu's sudden emergence, Wu Feifei would definitely be the most brilliant researcher in the research group.

Then came Tian Qing, she reported the research results of charge transport in a well-behaved manner.

Research in this area is relatively small, and it is difficult to publish a large article, but it is not difficult to publish a small article in conjunction with perovskite hotspots.

After that is Duan Yun, who is considered to have made it through. He just set up the equipment a few days ago and is now testing various standard samples.

In addition, Chen Wanqing and Xu Qiu just dropped an AM.

All five of them made good progress in the experiment, and it was rare for the group meeting to be peaceful.
