I Have a Research Support System

Xu Qiu thought carefully about his scientific research trip in the past few months.

In the early days, the main motivation for his efforts to move forward was the novelty of the scientific research field and the system that fell from the sky.

The system issued tasks, guided him to complete the tasks step by step, and gradually became familiar with the whole process of scientific research work.

At the same time, the improvement of proficiency and the increase of system points can also bring him instant feedback, telling him:

"Look, the experimental level has improved again today, and if you work harder, you will become stronger."

But later on, the sense of presence of the system was much lower.

Xu Qiu's motivation to do scientific research is more self-driven, because he has experienced the joy of scientific research:

Explore an unknown field, encounter problems, solve problems, and constantly challenge yourself.

Of course, Xu Qiu is not a great sage, so there are inevitably some utilitarian considerations about his personal future.

Although engaging in scientific research is not as profitable as doing business, it can easily cost as much as a small goal of 100 million.

However, top scientific researchers can also master a large amount of social resources, and it is not limited to wealth.

Money is essentially a social resource, the simplest and most direct one.

...

Tao Yan's voice brought Xu Qiu back to reality:

"Are you really doing experiments in Zhangjiang these two days?" Tao Yan asked suspiciously.

"Of course it's true, I'm not you." Xu Qiu said:

"Don't get in my way, I'm going to change and take a shower."

Tao Yan pretended to sniff at Xu Qiu, and said with disgust:

"For the smell on your body, I believe you did an experiment in Zhangjiang."

Xu Qiu also smelled it himself, but he didn't smell anything.

He shook his head, threw the dirty clothes into the basin, and asked casually:

"Tao Yan, why haven't you gone out for a while recently? Why have you been nestling in the dormitory?"

"He, he's broken in love." Ren Bin answered immediately.

"Really, a veteran in love, can he still stumble?" Xu Qiu said.

"Don't mention it, we broke up peacefully, and she wants to study abroad." Tao Yan said.

"I remember, isn't that a girl from the Chinese Department, who went abroad to study Chinese?" Xu Qiu said:

"A Ph.D. from the Chinese Department of Cambridge University?"

"You..." Tao Yan was choked, and he said impatiently:

"Why do you have so many questions, don't you want to take a bath, go and wash yourself."

When Xu Qiu came back after taking a shower, he saw Tao Yan already lying on the bed, covering himself under the blanket.

His head was not exposed, but there was a faint light on his quilt.

This is, autistic?

...

The next day, Xu Qiu and Chen Wanqing came to Zhangjiang to continue the post-processing of the fourth batch of reactions.

This time it was his turn to do a Soxhlet extraction with chloroform.

There are only two reaction systems, which are relatively relaxed.

After the product is processed and dried, it is weighed.

Xu Qiu's P2FBT4T-2HD system yielded 60 mg of product with a yield close to 50%.

However, the yield of Chen Wanqing's PBDTBTTT-37 system is still about 60%, which is relatively stable.

The time for the synthesis experiment this week was too tight. After the first and second batches of products were extracted with chloroform, there was no time to make devices to verify their photoelectric properties.

Next is the synthesis and post-treatment of the third batch and the fourth batch of products.

Therefore, this time, four batches of products were directly accumulated in Zhang Jiang's laboratory.

In the evening, the two returned to Handan Campus with four batches of products.

Similar to last week's experiment progress, the solution was also prepared on Thursday night, and a batch of devices could be made on Friday.

Xu Qiu prepared a total of six sets of solutions.

There are three of his, PBT4T, P2FBT4T-2BO and P2FBT4T-2HD.

They are numbered 1#, 2# and 3# respectively.

There are also three kinds of sisters, PBDTBTTT-37, PBDTBTTT-11 and PBDTBTTT-73.

They are respectively numbered 4#, 5# and 6#.

The solvents are all chlorobenzene solvents, the acceptor materials are all PC[70]BM, the donor/acceptor ratio is 1:1, and the total concentration is 16 mg/ml.

...

Friday morning.

Chen Wanqing did the preparatory work of cleaning the substrates and spin-coating the zinc oxide transfer layer, and prepared 24 substrates.

At the same time, she also split the three sets of solutions that Xu Qiu helped her prepare yesterday into six sets of solutions, three of which added 1% DIO solvent additive by volume, and the other three did not.

The three groups with added additives are numbered 7#, 8# and 9#.

Xu Qiu did not intend to add solvent additives, because the 1# system added solvent additives before, but the performance of the device was reduced, and this system may not be suitable for adding additives.

In the afternoon, Xu Qiu spin-coated the active layer, and each of their systems used 12 substrates.

Evaporate, test.

As a result, the highest efficiency of 1# was 6.12%, the highest efficiency of 2# was only 3.06%, and that of 3# reached 6.97%.

This shows that directly introducing two fluorine atoms without changing the branch chain, the photoelectric performance is not as good as the baseline system without introducing fluorine atoms, but if the length of its branch chain is increased, the performance will be significantly improved.

Now it is a unilateral upward trend. If the branch length is further increased, the efficiency may be further increased.

In the senior sister's system, 7# has the highest efficiency, reaching 8.24%.

From the perspective of efficiency alone, both of them have entered the threshold of the SCI second district.

However, Chen Wanqing's system potential has been exhausted, and Xu Qiu still has opportunities for further improvement.

Seeing the results of the experiment, she smiled and said happily:

"I achieved 8%, the hard work of this week was not in vain."

"Yeah, it's really tiring to do the synthesis, but it's still a sense of accomplishment when you get the result." Xu Qiu said:

"Sister, if you can publish one article for the second district, you will have three articles for the second district."

"Hey, it's one step closer to graduation," Chen Wanqing said:

"However, those two articles have not been officially published yet. Judging from the time, the comments on the first submitted article should come back soon. I hope there will be no moths."

Xu Qiu also thought about it in his mind, his opinion on the first article should be returned soon.

Before he knew it, it had been a month since he returned to school.

I spend most of my time in the laboratory, and I live a full life every day.

...

Sunday afternoon, material one 216.

"Sister, are you still making devices today?" Xu Qiu asked.

"Let's make another batch. I will use these three materials in this system and compare their performance with each other," Chen Wanqing said:

"Let's see if we can improve the efficiency today. If it can reach 9%, it will be relatively stable. If it can reach 10%, it will be even better."

Xu Qiu nodded, and then asked, "Wu Feifei, are you not making devices today?"

"You guys do it. I made three batches a few days ago when you were compositing. The data for this week is enough." Wu Feifei said.

After getting the answer, Xu Qiu began to think about how he would control the experimental conditions today.

But after thinking about it, the current 3# material is probably not the best material under this system, and the painstaking optimization seems to be of little significance.

At this moment, the sound of Mr. Wei's leather shoes "da da da" came from the door.

After he came in, he looked around and found that all his students had arrived, so he motioned to Xu Qiu and Chen Wanqing:

"You two, come with me."

Teacher Wei walked in front, and the two followed behind. They were silent with each other and communicated with each other with their eyes:

"What do you think Mr. Wei wants us to do?"

"I don't know, do you know?"

"What a coincidence, I don't know either."

Thank you for the 100 starting coins rewarded by Head Ou.
