Chapter 342: Karen Mok: I really deserve my name as the third author

"I have a scientific research support system novel ( to find the latest chapter!
At two o'clock in the afternoon, Wei Xingsi suddenly appeared at door 216 and said: "Xu Qiu, Han Jiaying, your comments on the JACS review have also been returned. I forwarded it to your mailbox."
Xu Qiu nodded and responded. In this article, he and Han Jiaying are the same, and the school girl ranks ahead of him, because the system involved is H22:ITIC, and the H22 is mainly developed by the school girl. Mo 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 reviewing the review comments, Xu Qiu found that the JACS of this school girl was "a little less lucky" than the AM he had just accepted, and the reviewers encountered were more demanding.
Although the opinions given by the three reviewers were all positive, it was more troublesome to revise. The final editor's opinion was a major revision, and the deadline was 20 days.
1#Reviewer requested supplementary resonance soft X-ray scattering (R-SoXS) characterization test.
Xu Qiu occasionally saw this test in articles published by some domestic colleagues, and knew that Qumodu Light Source could test it.
However, the line station tested by R-SoXS and GIWAXS are not in the same line station, and the test can only be performed when a separate application is required.
Unlike the hard X-ray of 10 or 18 kiloelectron volts used by GIWAXS, the soft X-ray of 284.8 eV used by R-SoXS is mainly used to characterize the phase separation information in the film, that is, the phase area can be tested. the size of.
For the traditional fullerene derivative system, the exciton diffusion distance is usually on the scale of 10 nanometers, and the phase area scale obtained by the best system test is usually about 10-20 nanometers.
The reviewers are more interested in whether this new high-performance ITIC non-fullerene material will have any unique performance in the size of the phase region.
This gave Xu Qiu an idea for future research, but when there is no time in his hands, it is obviously too late to test.
Every year in March and September, the light source will approve the application twice. They should be able to catch up with the approval in September, and the approval will be tested next year.
Thinking of this, Xu Qiu turned his head and said: "Mo Wenlin, you can write the application form for R-SoXS. I will give you the template for applying for GIWAXS before. You replace the GIWAXS in it with R-SoXS. Just replace some descriptions, such as changing'characterizing molecular structure' to'characterizing phase separation morphology information'. As long as you complete the first application, you can apply for the reward machine to achieve perpetual motion in the future by posting articles."
Mo Wenlin nodded in response: "Okay."
Han Jiaying asked: "How do you respond to this opinion?"
Xu Qiu said without hesitation: "We can only deal with it first, and you can reply like this. We are very grateful for your opinion, but for objective reasons we cannot test Barabara..."
The 2# reviewer said "Congratulations to the efficiency of another non-fullerene system that exceeded 10%", and then asked for "a third-party test report for battery devices."
Third-party inspection reports, this is indeed a problem. Now the efficiency is only 10%. It's okay to say. If the efficiency is further improved and try to break the world record, if there is no third-party inspection report, others will 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 ideas like "is your 12% really 12%?"; on the other hand, it is also to prevent data fraud.
After all, a JV curve, if you scan from minus 0.2 volts to 1.5 volts, with 0.02 volts as the interval, there are only 85 data points, it is too easy to fake, just "optimize" it, and double the efficiency is simple, and From the data alone, it is impossible to tell that it is fake data.
The 10% and 11% efficiencies of the IDTBR system of Xu Zhenghong's research group before have also been submitted for inspection.
Of course, not all reviewers will make such a request. For example, the AM of Xu Qiu PCE11 was not required to be submitted for inspection.
But for scientific research, we still have to be as complete as possible. If others don’t mention that it’s other people’s business, we still have to be as solid as possible in our work.
Otherwise, a job that is full of loopholes, no matter how good the results are, it will make people wonder: "Will it be a problem with the testing process, or simply fake data".
Xu Qiu also knows something about domestic testing institutions.
The largest is the National Institute of Metrology (NIM) in Beijing, which is the domestic testing organization with the highest specifications.
Zang Chaojun and Lu Changjun from Qingbei University and the Chinese Academy of Sciences are all in the capital. It was more convenient to send for inspection in the past;
As for Wei Xingsi, who is far away in the magic city, if the NIM is sent for inspection, the fastest way is to take the high-speed rail, which takes more than five hours on the road, and the device efficiency will definitely be lost.
Xu Qiu originally planned to take the second place and send it to the Institute of Metrology and Metrology for inspection.
It turns out that the photoelectric conversion efficiency test of organic solar energy cannot be carried out here, and it is true that there are some holes...
Other third-party testing agencies that Xu Qiu knows that can test the efficiency of organic solar cells are basically abroad.
There is no choice but to force NIM.
Xu Qiu turned around and said: "Mo Wenlin, the organization has entrusted you with a glorious task... sample preparation and a business trip to Beijing."
"Okay." Mo Wenlin responded with a smile on the face, secretly complaining to herself: "I, the third author, really deserves my name."
Xu Qiu logged into the NIM website and looked at the inspection flow chart, which stated that the inspection report usually takes 10-15 working days to get. ‘This is too long. The deadline for major changes to the article is only 20 days. ’
Then he took a closer look and found that the 10-15 working days is the time for instrument testing, and solar cell devices are not marked.
After calling for inquiry, the other party stated that the test report could be issued within 1-3 working days.
For example, the efficiency test of organic solar cells is a non-compulsory test. The procedures are 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 was curious to check the meaning of compulsory verification, and found that compulsory verification refers to the highest measurement used by the statutory measurement verification agency or authorized measurement verification agency of the government's metrological administrative department for social public measurement standards, departments, and enterprises. Standards are used for the work measuring instruments listed in the national compulsory inspection catalogue in the four areas of trade settlement, safety protection, medical health and environmental monitoring. A fixed-point and regular inspection is implemented.
It’s a bit difficult to understand just by looking at the definition, but looking at the things that need to be tested mandatory, including: rulers, thermometers, calorimeters, weights, balances, scales, and so on.
Xu Qiu immediately understood that the so-called compulsory verification is actually a literal meaning, and these things cannot appear on the market without verification.
After understanding the testing process, Xu Qiu began to pay attention to NIM's charging standards.
NIM checks first, then pays, and the test report can be obtained after payment. It supports cash, credit card, Beijing check and bank transfer, but does not support Alipay and WeChat.
It is also normal. Many administrative units do not support non-state third-party payment methods. For ordinary individuals, these third-party payments are more convenient, but for the system, it is more troublesome.
Then, Xu Qiu checked the price and tested a sample of 1,350 yuan.
He was stunned on the spot, which is more expensive than shooting TEM outside.
And this is the price of a battery for unidirectional scanning. 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 charged for each additional point.
Xu Qiu had to sigh with emotion: "The money of scientific research institutions in universities is really good..."
Fortunately, there is still a lot of test fees left in the group, all of which can be reimbursed, and it is not distressed.
This feeling is that the state sends out the money from the Natural Science Foundation, and then uses a monopolistic method to receive it back, with the left hand over the right.
The cost of testing and issuance of certificates must be no more than one hundred yuan. The current charges are almost two zeros added to the cost.
Xu Qiu went to 218 and reported the situation to Wei Xingsi: "...Do you want to send other systems with an efficiency of more than 10% to be tested?"
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 are you going to send?"
Xu Qiu replied: "Mo Wenlin, I am going to make an appointment to Thursday or Friday afternoon, because it will take some time to prepare the devices here."
Wei Xingsi nodded: "Yes, just do that."
Except for the two problems of supplementary test R-SoXS and supplementary third-party test report, the other problems raised by the reviewer are relatively simple, and Han Jiaying can solve it alone.
Back to 216, Xu Qiu took a look at the existing systems with an efficiency of more than 10%, and found that there were still quite a few.
Including his own IT-4F, IT-DM, Wu Shengnan’s FN-4F, Mo Wenlin’s three ternary systems, Chen Wanqing’s -4F, Han Jiaying’s PBDB-TS, H43, plus the current JACS H22, a total of ten Samples.
I tested so many at once, and I don’t know if it can be discounted...
Well, there is a high probability that I think too much.
Counting on black shops to be able to discount, the difficulty is tantamount to making pheasants good...
Xu Qiu found the contact information of the examiner on the Internet, and then made an appointment with him for the test on Thursday afternoon.
This time the samples need to travel a long distance to Beijing, UU reading www. uukanshu.com hopes that the results of third-party testing and laboratory results will not deviate too much.
Under normal circumstances, there will be deviations in the detection, and it is generally considered that deviations within 5% or within 10% are acceptable.
Like Xu Zhenghong's IDTBR system, the highest efficiency is 11%, the calibration value is 10.63%, and the deviation is about 3%.
Xu Qiu replaced the original mask with a size of 0.09 square centimeters and asked Mo Wenlin to make several batches of devices to ensure that each sample has more than two devices that reach the highest efficiency value.
As for why the original mask should be changed, it is mainly because NIM testing is charged once for each point tested. He must ensure that the device sent to the third party for testing is the one with the best performance.
However, it is difficult to guarantee with a shield.
