On Friday morning, Xu Qiu j2:idic-4f system, the first draft of the article "Nature·Energy" was born. There are seven highlights:
First of all, the most eye-catching nature is the device efficiency, which reached a maximum of 13.33%, and the third-party nim test result was 13.2%, which marked the leap from the perennial "12% era" to the "super 12% era" in the organic photovoltaic field.
Second, a large area device was prepared, that is, the efficiency data under a 1 square centimeter shielding plate reached 10.24%. Originally, the ito pattern designed by Xu Qiu was 2 square centimeters. It can measure 1 square centimeter without the shielding plate, but 2 square meters. The data under the centimeter is only 8.73%, not more than 10%. The data is not very good-looking, so Xu Qiu chose 1 square centimeter to break 10%.
Third, a thick film device was prepared. The efficiency of a device with a thickness of 300 nanometers can reach 10.42%, and a device with a thickness of 500 nanometers can still reach an efficiency of 6.35%. Most organic photovoltaic systems are 500 nanometers thick, and the efficiency of the device is directly clear. When it is zero, it shows the phenomenon of open circuit.
Fourth, a set of theoretical explanations is proposed: Compared with the itic structure, the side chain of the idic-4f system has changed (molecular structure design) → intermolecular steric hindrance is reduced (dft result) → the acceptor molecule arrangement in the effective layer changes Get close (giwaxs result) → increase electron mobility (celiv, tof, sclc result) → reduce energy loss and increase open circuit voltage (jv curve result).
Fifth, another set of theoretical explanations is proposed: Compared with the idic structure, idic-4f introduces fluorine atoms (molecular structure design) → enhanced intramolecular interaction (according to earlier theories proposed by other researchers) → acceptor material The homo/lumo energy level becomes deeper, the light absorption red shifts (cv, uv-vis results) → the short-circuit current increases, and the open circuit voltage increases (jv curve result).
Sixth, similar to the h43:it-4f system before the school girl, the energy level difference between the j2:idic-4f system to the acceptor is also relatively small, only 0.16 electron volts (cv result), and it also shows excellent charge output. Transport performance (pl, trpl, tas results), theoretically explained as idic-4f material has low exciton binding energy.
Seventh, for the phenomenon that the efficiency of large area and thick film devices are both broken by 10%, a possible theoretical explanation is also given, that is, the exciton diffusion distance of idic-4f material is very high, and the r-soxs result shows that the scale of the aggregation phase reaches More than 30 nanometers, which is larger than the traditional fullerene system, provides further evidence.
After taking an inventory, most of the dozens of characterization tests are connected in series. Only the electron microscope data such as tem and afm are useless, because the image that is actually taken is a piece of white flowers, and nothing can be seen.
Therefore, Xu Qiu mentioned a general phrase in the article for these two representations, which probably means "the results show that the shape of the effective layer is good", and then the data is thrown into the supporting information.
In the afternoon, Xu Qiu headed to 218 with a draft of the article that was read and revised by each author in the research group.
Wei Xingsi smiled, took the USB flash drive that Xu Qiu handed over, and said, "Here, has the article been seen by others?"
"Well, I changed it all over again." Xu Qiu nodded.
"Okay, I'll take a look." Wei Xingsiguang stared at the computer screen, his brain running fast, and occasionally commented.
"Well, the title is okay. It highlights the three highlights of high efficiency, large area, and thick film."
Although there may be many highlights of an article, it is impossible to write all of them in the title. That would be too bloated. Therefore, Xu Qiu put the three core highlights on the title.
"The author...no problem."
The authors of this article have a long row of ten, divided into three work units:
Among them, one is Xu Qiu, two is Han Jiaying, three is Tian Qing, four is Wu Shengnan, five is Mo Wenlin, six is ​​Chen Wanqing, seven is Gong Yuanjiang, eight is Feng Shengdong for communication, nine is t?nu, and ten is for Wei Xingsi.
Considering that the contributions of Tian Qing and Han Jiaying are very high, the former was responsible for the testing of four mechanisms and optimized the pictures of the article, and the latter was responsible for most of the basic characterization tests, as well as the preparation and testing of the devices. For the sake of fairness, Xu Qiu asked them to guess the box and decide the ownership of the second article by winning three games.
In the end, the school girl won two games with two consecutive victories.
However, Professor Gong Yuanjiang and t?nu did not contribute much to this work. They belonged to the type of naming, so naturally there was no communication, just like the several articles "Nature" that Wei Xingsi wrote in the nrel research of beautiful country. "Da Zi Magazine, this is almost a similar situation.
After reading the title and author, it is the abstract part.
Wei Xingsi read the summary in one breath, and there was no jam during the whole process, which gave him a refreshing feeling, and there was almost nothing that could be modified.
He couldn't help thinking, if nothing was changed, wouldn't I, the corresponding author, have done nothing, this would not work.
Therefore, Xu Qiu saw that Teacher Wei changed the "indicate" in the summary to "reveal"...
After changing a few more synonyms, Wei Xingsi nodded in satisfaction before continuing to read the body of the article.
Usually when Xu Qiu and Wei Xingsi read the literature, they can read ten lines at a glance and only browse the key information. You can read one in three to five minutes, but now you can modify your own article, an article in article format, and read 5000+ Vocabulary, not every half an hour, an hour can’t be written.
Fortunately, Xu Qiu’s ability to write articles now is not as good as when he first entered the research group, and has basically reached the level of Wei Xingsi. Therefore, he basically does not commit more elementary grammar and tense problems, and the difficulty of editing the article. Reduced a lot.
Two hours later, Wei Xingsi read the article twice, including subtitles, legends for each picture, supporting information, and even references, author contributions, and other parts.
Teacher Wei let go of the mouse and keyboard, moved his cervical spine, and then relaxed on the backrest and said, "Very good, let's throw it away. I hope we can win an "Nature·Energy"."
Subsequently, the two moved to the office computer and began the cumbersome submission process: copy and paste the title, abstract, coverletter, and keywords, fill in the detailed information of each author, fill in the detailed information of the recommended reviewer, and fill in the banned reviewer. The detailed information of the author, upload the main text, original data, supporting information and other documents...
Xu Qiu stood by and saw that Teacher Wei's hands were a little trembling during the operation, as if he had Parkinson's.
However, the symptoms are not very obvious, probably in the early stage of Parkinson?
The submission process was a bit more troublesome, but there were no problems.
After half an hour, Wei Xingsi pressed the "Submit" button and saw the animation of "The manuscript flew away" showing the successful submission. He took a long breath and said: "The members of the research team will go out for a meal tonight. An undergraduate also called, I won’t pass."
"Okay." Xu Qiu nodded.
In fact, even if Teacher Wei doesn’t say anything, Xu Qiu plans to organize a dinner party tonight. He has been busy writing articles these days. Although he didn’t do much experiment, he was actually quite tired. Now that he is finally done, he naturally wants to treat him. Take a look at yourself.
When Xu Qiu returned to 216, it was about 4:30 in the afternoon.
He posted the news about the dinner at six in the evening in the group chat of the research group, and then looked at the situation of everyone.
At the desk, Chen Wanqing is writing an article, Duan Yun is browsing the recruitment information, Mo Wenlin is reading the literature carefully, Tian Qing is playing on the phone, and seems to be chatting with people;
In the laboratory, Han Jiaying took Xu Xinjie to test the devices in the laboratory, and Wu Feifei took Yu Ya to learn the preparation of perovskite solution;
In addition, Wu Shengnan took Yin Houlang to do a synthesis experiment in Zhangjiang, and now he is going to return to the Handan campus;
Deng Hu didn't come to the laboratory because he had something to do today, but he said that he would arrive on time for the evening dinner.
On the whole, the "quality" of this group of newly entry undergraduates is relatively good and highly motivated.
At 5:30 in the evening, everyone in the laboratory assembled and set off in a mighty manner to the restaurant "Tian Spicy" that Xu Qiu had booked in advance. I visited this restaurant once before. The price of regular Sichuan cuisine was fairly affordable.
Mainly because there are a lot of people this time. If you eat hot pot or something, 13 people estimate that a meal will cost 2,000. If you order, you can have a few more pots of rice, and everyone will do the meal together.
Thirteen people sat around a large table, ordered dishes, controlled the total price of the dishes to be within 1,000 yuan, and then ordered a 2 liters of fruit orange and 2 liters of Qiup.
Two new undergraduates, Yin Houlang and Deng Hu, are more likely to come. UU Reading www.uukanshu.com got up and poured a drink for everyone.
Tian Qing first toasted and said: "Let's have a drink together, congratulations Xu Qiuxi for bringing up an article "Nature·Energy"."
Xu Qiu waved his hand hurriedly: "The article has just been voted out, why..."
Duan Yun interrupted: "In my opinion, Xu Qiu will definitely be able to pass this article. If it fails, it will also be a loss for "Nature Energy"."
Chen Wanqing roared and said, "Brother, I can be regarded as half of your master. Round up, this article is equivalent to what I published, 嚯嚯嚯..."
Wu Feifei was half joking: "Xu Qiu, are you interested in changing careers and come over to do perovskite? There are more opportunities here."
Han Jiaying said in a serious tone: "Brother, I believe this "Nature·Energy" is just your starting point, not the end point. Next time you will win the s main issue~"
Karen Mok echoed: "I think what Jiaying said makes sense, so let's vote for Nature in the next article."
Wu Shengnan carefully analyzed: "Xu Qiu, I think your article is written very well in language, logically and smoothly, and there are many highlights. If I were a reviewer, I would definitely let you pass it."
Sun Wo is simple and rude: "Must hit!"
Yin Houlang is polite and gentle: "I wish my brother's article a smooth publication."
Deng Hu spoke with a northeastern accent: "Brother Xu Qiu, the article is absolutely correct."
Xu Xinjie smiled lightly: "Congratulations brother~"
Yu Ya seemed a little shy, and said along the way: "Congratulations, brother."
Xu Qiu was very moved by the serious or irregular blessings of other friends, so he waved his hand and called the waiter to add three more dishes.
