I Have a Research Support System

The first is to design the experimental content, mainly including Xu Qiu's own system P4T, and Han Jiaying's two systems P3T and P5T.

After all, the junior has helped him a lot during this time, and it is only right to help her try the optimal conditions for the experiment in return.

As for the systems of the senior sister, there is no need to test because the thermal spin coating method has not improved significantly.

Add up a total of three systems, each system has five processing temperatures, five rotation speeds, and a total of 75 sets of conditions.

It seems that there is still a lot of experimental content today.

In the simulation laboratory, many zinc oxide substrates have been copied before, but there is no need to start experiments from scratch, and the effective layer can be directly spin-coated on the substrate.

After Xu Qiu took a few deep breaths, he started the experiment.

Place the substrate, pipette the solution, turn on the spin, spray, and discard the pipette tip, all in one go.

Under the quadruple acceleration, the whole process takes no more than thirty seconds, just like an emotionless spin-coating machine.

He spin-coated a total of 81 times, of which 6 times the films obtained were not perfect, so they were thrown away and redone.

It took less than an hour.

If this experiment is done in reality, the experimental time required is conservatively estimated to be two to three hours.

After the experiment was done, a whole morning passed.

After that, Xu Qiu divided these devices into four batches for evaporation and testing.

Speaking of testing, he heard that in some research groups, the simulated solar light source is not integrated in the evaporation glove box, but placed outside the glove box, that is, exposed to the air.

When testing, it is necessary to put the substrate in a similar sample holder, and then take it out for testing.

In this case, the difficulty of the test will increase significantly.

On the one hand, in order to ensure the airtightness of the sample holder, four screws are used to fix it. Every time the sample is replaced, it must be disassembled and assembled again. On the other hand, the sample holder must be pumped three times every time it enters and exits the glove box.

The fixed time cost is too high, even if there is a system, the experiment speed will be much slower.

Fortunately, he doesn't need to worry about this problem, and can complete the test directly in the glove box.

Under the quadruple acceleration, the test speed is very fast, and it will be over soon.

Xu Qiu's system has a maximum efficiency of 11.10%.

The dramatic thing is that the optimal experimental conditions are actually the same as the ones done in reality today, still 100 degrees Celsius, 3500r.p.m.

Although it was a little unexpected, it was also reasonable. After all, the solutions used in the two experiments were different, and the old solution might have a higher concentration.

As for Xuemei's two systems, one has a maximum efficiency of 7.23%, the condition is 90 degrees Celsius, 3000r.p.m., and the other has a maximum efficiency of 6.77%.

Unfortunately, her system currently has no hope of hitting 8%.

...

Thursday morning.

We must make devices today, and repeat the results in the simulation laboratory yesterday.

When Xu Qiu went to the laboratory and saw Han Jiaying preparing light source samples, he didn't bother her and decided to experiment by himself.

Just applied 81 tablets yesterday, and now my hands are hot.

However, to do experiments in reality, we must start with cleaning the substrate.

Fortunately, Xuemei has a good habit. She will keep a batch of clean substrates that have been cleaned with isopropanol, and take them out and blow dry them when needed.

In addition, including the commonly used solution of zinc oxide prepolymer solution, she reconstitutes it once a week for backup.

This can save a lot of time when the device is officially made.

For example, Chen Wanqing doesn't have such a habit, and neither does Xu Qiu. This is a good habit of a school girl spontaneously, and it is commendable.

Brush, brush, zinc oxide substrate is spin-coated.

While waiting for the substrate to be annealed, Xu Qiu returned to his desk and sat next to Chen Wanqing, preparing to process yesterday's CELIV data.

He glanced at the senior sister's computer, she was also processing yesterday's UV-vis data.

In the ORIGIN software on her screen, a bunch of colorful curves are drawn, and the changing trend looks really obvious.

At this moment, out of the corner of Xu Qiu's eye, he saw a dark shadow at the door of 216.

He raised his head and took a closer look, and it turned out to be Teacher Wei.

For a moment, the two looked at each other.

Xu Qiu was startled, am I being targeted by the boss?

But after thinking about it, I didn't do anything wrong, so I relaxed and began to think:

Teacher Wei suddenly appeared at the door without making a sound. It seemed that he rushed over in a hurry. What's the matter?

Could it be...

"Xu Qiu, your review comments for AM's article are back. I took a quick look at it." After finishing speaking, Wei Xingsi changed his smile and continued:

"The three reviewers all gave positive comments. The comments given by the editor are minor changes. I forwarded the email to you two. Please take a look, write a reply, and make a good revision of the text. This Friday we will Get this thing over."

"Okay." Xu Qiu was right as expected, it really was about the article.

He was also excited in his heart. After waiting for nearly two months, there was finally news, and it was positive news.

Wu Feifei, Duan Yun and others at the desk cast envious glances, but because Teacher Wei was still there, they didn't take the initiative to say congratulations.

Xu Qiu thought of yesterday's experimental results, organized his words, and said:

"Mr. Wei, my system yesterday used a new spin-coating instrument to prepare a batch of devices, and the efficiency reached 10.9%. I think it is possible to further break through to 11%, so I plan to make two more batches of devices to try." Try, and I am going to name our material PCE11, what do you think?"

"oh?"

"Efficiency can reach 11%?

"Is there a name change to PCE11?"

Wei Xingsi stood where he was, pondered for a while, then nodded and said:

"Well, yes, you have a good idea, just try it according to your idea, you can give me the revision of the article later, but it's not too late, before Sunday, how about it?"

"Okay." Xu Qiu agreed.

After Teacher Wei left, Chen Wanqing smiled and said, "Congratulations, junior, I'm going to mention an AM soon."

"It hasn't been published yet," Xu Qiu said modestly, then cupped his hands and said, "And senior sister is also a second author, congratulations, congratulations."

Duan Yun next to him couldn't help but interjected: "Xu Qiu, I think we can prepare a treat in advance, three positive comments, minor editorial changes, the probability of the article being accepted is ninety-nine percent."

"If the article is really published, a treat is a must," Xu Qiu said: "Let's look at the opinions first, and if we need to add some experiments, such as TRPL, which we can't test, it will be more difficult to do, right , Sister, you can also help me take a look."

...

Opening the email, Xu Qiu noticed the time information.

He received it six minutes ago, and the editor sent it to Teacher Wei fourteen minutes ago.

It seems that Teacher Wei should have browsed through the email after receiving it, and hurried over to notify him.

Xu Qiu also read the email first.

The core point is basically the same as what Mr. Wei said before. The editor’s opinion is slightly revised, and the deadline is 10 days. Three reviewers, one suggests to accept it directly, and the other two raise some questions and suggest minor revisions.

Originally, Xu Qiu thought that there would be many reviewers, but there were only three.

This time, it is difficult to judge whether the reviewers are domestic or not. I can only see that one of them has a high probability of suggesting minor changes.

It takes an hour to anneal the zinc oxide substrate, and now there are more than 30 minutes left.

Xu Qiu judged that there would be too little time to complete the reply letter.

Instead, you can list out the general framework first, and then slowly fill in the content while taking advantage of the gap between experiments, just like writing an article.

So, he created a new WORD document, copied the comments in the email, and began to reply one by one.

First of all, it is recommended to accept that person directly. His comments are only a few sentences, which is easier to deal with.

Xu Qiu replied directly: "Thank you very much for your objective evaluation."

The opinions of the other two reviewers are relatively more:

Article 1, "Please supplement the standard deviation data in the photoelectric performance table."

Xu Qiu remembered that he had listed the standard deviation data. After returning to the text to check, he found that the photoelectric conversion efficiency was calculated, but other parameters were not calculated.

From this point of view, the reviewer's meaning should be to list the other three optoelectronic parameters, the standard deviation of short-circuit current density, open-circuit voltage, and fill factor.

Worthy of being an AM, it is much stricter. He has not found this problem when he was submitting to other journals before.

So, he replied: "Thank you for your comments, we have made changes accordingly."

Due to time constraints, he highlighted the parts that need to be revised in the text.

The second article, "Please add the integral curve of the EQE results corresponding to the photogenerated current density."

This integral curve is relatively easy to do, without supplementary experiments, it can be calculated and exported directly with the software that comes with EQE.

Generally, no one would draw this graph specially, Xu Qiu followed the usual practice and only listed the final score data.

However, the reviewers are all uncles. Since they have been mentioned, some innocuous opinions should be adopted.

Maybe the reviewers couldn't find any other faults, so they forcibly picked the bones in the eggs, which is also possible.

Xu Qiu replied: "Thank you for your opinion, we have added corresponding pictures."

It is worth noting that the expressions here are "thank you for your opinion" in Chinese, but there will be different expressions in English.

This is also what he learned from Chen Wanqing's reply. At that time, there were nine comments from the reviewers of her article. She thanked her nine times in total, and each time the expression was different.

However, most of the revisions were made by Teacher Wei. If it was a senior sister, she should only be able to say: "Thank you..."

Article 3, "On page 7, line 19, there is a typo."

This is easier to change, Xu Qiu can modify it directly in the text.

It is still very difficult to write an article without making a single mistake, after all, there are thousands of words.

Although WORD has its own error correction function, but when it comes to proper nouns, it will definitely miss something if only relying on intelligent error correction.

However, the reviewers did not say that the article needs to be polished, which shows that the article still passes the language level.

Article 4, "Please add the specific operation of the thermal spin coating method mentioned in the article."

In the experimental procedure, Xu Qiu did not describe it in detail, but only said that "using a hot solution and performing thermal spin coating at a speed of 2500r.p.m. to obtain an effective layer film."

For example, the use of 20 microliters of solution, the spraying method, the dihedral angle between the pipette and the surface of the substrate during spraying is about 45 degrees, and the need to heat the substrate and the solution at the same time. These specific operational information have been hidden by him.

To be honest, the question asked by the reviewer was somewhat beyond his expectation. Maybe the other party is very interested in this work.

Because the specific experimental methods are placed in the supporting information section, when he is reviewing the manuscript, he usually does not read this part very carefully, and generally scans it.

After thinking for a while, Xu Qiu decided to write down the parameters of the new equipment, which was similar to "We have adopted the XX type heating glue homogenizer, and the condition is...".

The main revisions are only these four. After reading all of them, Xu Qiu already has a bottom line in his mind.

This AM is basically stable.
