I Have a Research Support System

At 2 o'clock in the afternoon, Wei Xingsi suddenly appeared at the door of 216 and said, "Xu Qiu, Han Jiaying, the review comments of the JACS paper you two have returned, and I forwarded it to your mailbox."

Xu Qiu nodded in agreement. He and Han Jiaying shared the same article in this article, and the junior was ranked ahead of him, because the system involved was H22:ITIC, and H22 was mainly developed by the junior, and the third work was listed as Ma Wenlin.

Xu Qiu turned on the computer and checked the review comments with Han Jiaying. Mo Wenlin also pulled a stool and sat behind to watch.

After browsing through the review comments, Xu Qiu found that this JACS of the school girl was "less lucky" than the AM he had just accepted, and the reviewers he encountered were more stringent.

Although the opinions given by the three reviewers are all positive, it is more troublesome to revise, and the final editor's opinion is a major revision, with a deadline of 20 days.

Reviewer #1 requested additional resonant soft X-ray scattering (R-SoXS) characterization tests.

This test, Xu Qiu can occasionally see it in articles published by some domestic colleagues, and he also knows that it can be tested by going to the light source of the magic city.

However, the test station of R-SoXS and GIWAXS are not in the same station, so it is necessary to apply for a separate machine to test.

Unlike the 10 or 18 keV hard X-rays used by GIWAXS, R-SoXS uses 284.8 eV soft X-rays, which are mainly used to characterize the phase separation information in thin films, that is, the phase region can be obtained by testing the size of.

For the system of traditional fullerene derivatives, the exciton diffusion distance is usually on the scale of 10 nanometers, and the phase region scale obtained by the best system test is usually around 10-20 nanometers.

What the reviewers are more interested in is whether this new high-performance ITIC non-fullerene material will have any unique performance in the size of the phase domain.

This gave Xu Qiu an idea for future research, but now that he doesn't have a computer in hand, it's obviously too late to test it.

Every year in March and September, the light source will approve the application twice, and they should be able to catch up with the approval in September, and it will be a matter of next year to pass the approval.

Thinking of this, Xu Qiu turned his head and said: "Mo Wenlin, please write the application form for R-SoXS. I will give you the template for applying for GIWAXS later. You can replace the GIWAXS in it with R-SoXS. Just replace some descriptions, such as changing 'representing molecular stacking structure' to 'representing phase separation morphology information', as long as the first application is completed, you can apply for a reward machine by posting articles in the future to achieve perpetual motion."

Mo Wenlin nodded in response: "Okay."

Han Jiaying asked, "How do I reply to this opinion?"

Xu Qiu said without hesitation: "I can only deal with it first. You can reply like this. We are very grateful for your opinion, but due to objective reasons, we cannot test Barabara..."

Reviewer 2# said "Congratulations to another non-fullerene system whose efficiency has broken through 10%", and then requested "issue a third-party test report for battery devices".

The third-party test report, this is indeed a problem. It’s okay to say that the efficiency is only 10% now. If the efficiency is further improved in the future and tries to break the world record, if there is no third-party test report, others may not necessarily recognize it.

On the one hand, the test methods and test conditions of different laboratories are not exactly the same, and it is inevitable that there will be thoughts like "Is your 12% really 12%?" On the other hand, it is also to prevent data falsification.

After all, if a J-V curve is scanned from negative 0.2 volts to 1.5 volts at an interval of 0.02 volts, there are only 85 data points. It is too easy to fake it. Just "optimize" it and double the efficiency. From the data alone, it is impossible to tell that it is fake data.

For example, the 10% and 11% efficiency of the IDTBR system of Xu Zhenghong's research group have also been submitted for inspection.

Of course, not all reviewers will make such a request. For example, Xu Qiu's PCE11 AM paper was not required to be submitted for review.

But when it comes to scientific research, you still have to try to be as complete as possible. If others don't mention that it's someone else's business, you should do your own work as solidly as possible.

Otherwise, a job full of loopholes, no matter how good the results are, will make people doubt: "Could it be a problem in the testing process, or simply fake data."

Xu Qiu also knew a little about domestic testing agencies.

The largest is the National Institute of Metrology (NIM) in Beijing, which is the highest-standard testing institution in China.

For example, Zang Chaojun and Lu Changjun of Qingbei University and the Chinese Academy of Sciences are all in the capital, so it was more convenient to submit them for inspection in the past;

For those as far away as Wei Xingsi, if they are sent to NIM for inspection, the fastest way is to take the high-speed rail, which takes more than five hours on the way, and the efficiency of the device will definitely be lost.

Xu Qiu originally planned to settle for the next best thing and send him to the Metropolitan Institute of Metrology for inspection.

It turns out that the photoelectric conversion efficiency test of organic solar energy cannot be carried out here, which is true and some pitfalls...

As far as Xu Qiu knows, the third-party testing agencies that can test the efficiency of organic solar cells are basically located abroad.

There is no way but to force NIM.

Xu Qiu turned his head and ordered: "Mo Wenlin, the organization has entrusted you with an honorable task...sample preparation and a business trip to the capital."

"Okay." Mo Wenlin responded with a smile on the surface, and secretly complained in her heart: "I really deserve my name as the third author."

Xu Qiu logged on to the NIM website and looked at the inspection flow chart. It said that the inspection report usually takes 10-15 working days to get it. ‘This is too long, the deadline for major revisions of the article is only twenty days. '

Then he took a closer look and found that 10-15 working days is the time for instrument testing, but solar cell devices are not marked.

After calling to inquire, the other party said that the test report can be issued within 1-3 working days.

For example, the efficiency test of organic solar cells is a non-mandatory test, and the procedure is relatively simple. You only need to bring the sample to the test. If it is a mandatory test, you need to issue relevant certification materials.

Xu Qiu curiously checked the meaning of compulsory verification, and found that compulsory verification refers to the highest measurement standards used by public measurement standards, departments and enterprises and institutions by the statutory metrological verification institutions affiliated to the government metrology administrative department or authorized metrological verification institutions. Standards, used for trade settlement, safety protection, medical and health and environmental monitoring four aspects of working measuring instruments included in the national compulsory inspection catalog, a fixed-point and regular inspection is implemented.

Just looking at the definition is a bit difficult to understand, but I took a look at the things that need to be tested, including: rulers, thermometers, calorimeters, weights, balances, scales, etc.

Xu Qiu immediately understood that the so-called compulsory verification was actually a literal meaning, these things cannot appear on the market without passing the verification.

After learning about the testing process, Xu Qiu began to pay attention to NIM's charging standards.

NIM is to test first, then pay, and you can get the test report after paying. It supports cash, credit card, capital check and bank remittance, but does not support Alipay and WeChat.

It's normal. Many administrative units do not support non-state-owned third-party payment methods. For ordinary people, these third-party payments are more convenient, but for the system, they are more troublesome.

Then, Xu Qiu checked the price, and it cost 1350 yuan to test a sample.

He was stunned on the spot, which was more expensive than taking TEM outside.

And this is the price of one-way scanning of a battery. If a perovskite solar cell requires forward scanning and reverse scanning, the price will double.

If there are multiple sample points on the same device, an additional 1350 yuan will be paid for each additional point.

Xu Qiu had to say with emotion: "The money of scientific research institutions in universities is really easy to make..."

Fortunately, there are still a lot of testing fees left in the group, which can be reimbursed, and I don't feel distressed.

This feeling is that the state sends money from the Natural Science Foundation, and then uses monopoly means to receive it back, with the left hand and the right hand.

The cost of testing and issuing the certificate must not exceed one hundred yuan. The current charge is almost the cost plus two zeros.

Xu Qiu went to 218 and reported the situation to Wei Xingsi: "...do you want to send other systems with an efficiency exceeding 10% for testing?"

Teacher Wei was not very surprised by the price, and immediately said: "Let's test it all, this money can't be saved, by the way, who do you plan to send there?"

Xu Qiu replied: "Mo Wenlin, I plan to make an appointment until Thursday or Friday afternoon, because it will take some time to prepare the devices here."

Wei Xingsi nodded: "Okay, let's do it like this."

Except for the supplementary R-SoXS test and the supplementary third-party test report, other questions raised by the reviewers are relatively simple, and Han Jiaying can solve them alone.

Back at 216, Xu Qiu took stock of the existing systems with an efficiency of over 10%, and found that there were quite a lot of them.

Including his own IT-4F, IT-DM, Wu Shengnan's FN-4F, Mo Wenlin's three ternary systems, Chen Wanqing's IEICO-4F, Han Jiaying's PBDB-TS, H43, plus the current JACS's H22, a total of Ten samples.

There are so many tests at one time, and I don’t know if I can get a discount...

Well, there is a high probability that I am thinking too much.

Counting on black shops to offer discounts, the difficulty is tantamount to getting pheasants to be good...

Xu Qiu found the examiner's contact information on the Internet, and then made an appointment with him for the test on Thursday afternoon.

This time the samples need to travel long distances to the capital. I hope that the results of the third-party testing and the results in the laboratory will not deviate too much.

Under normal circumstances, there will be deviations in the detection, and it is generally considered that the deviation is within 5%, or within 10%, which is acceptable.

Like Xu Zhenghong's IDTBR system, the highest efficiency is just over 11%, the calibration value is 10.63%, and the deviation is about 3%.

Xu Qiu replaced the mask with the original size of 0.09 square centimeters, and asked Mo Wenlin to make several batches of devices to ensure that each sample had more than two devices that reached the highest efficiency value.

As for why the original mask needs to be replaced, the main reason is that NIM testing is charged once for each point tested, and he must ensure that the device sent to the third party for testing is the one with the best performance.

But with a visor, it is difficult to guarantee.
