I Have a Research Support System

　　 After the four people arrived at the cafeteria, they ordered the food separately, and then regrouped on a small table for four.

Xu Qiu ordered a laoya vermicelli soup, a cage of Jinling Xiaolongbao; Chen Wanqing had a meat, two, and two or two rice dishes on the dinner plate; Tian Qing ordered a small row of fried rice noodles; Duan Yun carried a large The hot and spicy hot pot is also served with two bowls of rice.

　　 While eating, they talked about campus gossip.

　　 "My roommate is from the He Xilan group, he is miserable." Duan Yun shared with interest:

　　 "Yesterday afternoon, He Xilan told them that she had something to do and she would not come tonight.

　　 So, the five people in their research group let themselves go and started the Black Fight King League in the laboratory.

　　 However, at eight o'clock in the evening, He Ceylan went back to the laboratory to kill a carbine and caught them upright.

　　 In the end, all five people were fined for five minutes to self-criticize at the group meeting, and then write another review. "

　　 "This is fishing law enforcement," Tian Qing answered:

　　" Moreover, He Xilan has a bad temper and often insults students. Her reputation spread in the Department of Materials.

　　 The students she enrolled in these years have basically been from other schools. The students in this school know how she is and no one dares to go.

　　 It is said that last year there was a master student who went to her group for half a year, but had some psychological problems and then dropped out.

However, she has a high level of scientific research. She has published "Nature" twice, one was when she was studying abroad in Neon, and the other one was written by a doctoral student in our school three years ago. of.

　　 So there are still many students who look for her as a mentor every year. "

　　 Tian Qing suddenly lowered her voice and said, "It is said that between her and Teacher Wei..."

　　 When the others heard the gossip, they stopped their chopsticks.

　　 Tian Haru continued: "It seems that I used to be a roommate."

　　 Duan Yun: "Roommates? Really or not, they can still be roommates with a man and a woman."

　　 Haru Tian: "I shared a lease when studying abroad."

　　 Duan Yun: "How do you know this kind of thing."

　　 Tian Qing: "Well... I listened to what my classmate said, and she said she listened to her classmate."

　　 Duan Yun: "It turned out to be gossip."

　　 Xu Qiu quietly eats melon next to him, feeling in his heart, the daily chat of graduate students is really three sentences inseparable from the tutor.

　　…………

　　 The four of them had dinner and returned to the laboratory together.

　　 Xu Qiu went to the main console to check, the vacuum gauge indicated 8.9E-5 Pa, the molecular pump speed was 27000r.p.m., everything was normal, and the experiment could be continued.

　　 He first set the parameters of the film thickness meter to molybdenum trioxide.

　　 Then adjust the heating program and start the program.

　　SP1400

　　RATE30

　　TIME3

　　SP2560

　　RATE20

　　TIME100

　　 Only two steps are required this time, because the heating program is started after the vacuum is reached, so no initial waiting time is required.

　　The subsequent evaporation operation is similar to the first batch of devices.

　　 More than an hour later, no accidents happened.

　　 Xu Qiu obtained 10 substrates that had been vapor-deposited, took them out, and put them in a petri dish.

　　 Then, he opened the system interface:

　　【Scientific Research Support System】

　　 Permission level: 1

　　 Points: 978

　　 Tasks in progress: 1

　　 Proficiency:

　　【Experimental operation class】

　　 Cleaning the substrate (fourth order 20%/fourth order 50%, ultrasonic cleaner, tweezers, nitrogen gun required)

　　 solution preparation (fourth order 10%/fourth order 50%, need glove box, heating stirring table, disposable syringe, medicine spoon, pipette)

　　 spin coating (fourth order 0%/fourth order 50%, need ozone generator, homogenizer, disposable syringe, tweezers, pipette gun, heating mixing table)

　　 Evaporation (three-stage 0%/fourth-stage 50%, glove box, evaporation equipment required)

　　【Instrument equipment tools】

　　……

　　【Special category】

　　 Literature reading (94% for the first order / 50% for the fourth order)

　　 Novice Task V: Raise the proficiency of any four experimental operations to Tier 4 or above, reward 1000 points for completion of the task, and start advanced tasks.

　　##

　　 Seeing that there is only 0% vapor deposition proficiency in the third order, Xu Qiu has a headache.

　　 If you want to master this proficiency, you have to make solar cell devices, and you must do it from scratch. You can't use an empty substrate to vaporize it.

　　 "Xu Qiu, what's the matter with you?" Chen Wanqing cared when she saw him in a daze in the glove box.

　　 "It's okay, I'm okay, I was just wondering whether vacuum coating can be used to vaporize other things." Xu Qiu said.

"Other things..." Chen Wanqing thought for a while, and said: "Yes, we used gold as an electrode to prepare battery devices before. During the deposition of gold, by the way, I put a few round iron pieces in the cabin, and then They are gold coins, but they are one-sided."

　　 "Sounds pretty fun." Xu Qiu said.

　　 Unfortunately, he didn't get the answer he wanted, so he could only think of other ways.

　　 If you want to reach Tier 4, you need to make at least two batches of devices so that you can complete the novice task V and unlock the advanced task.

　　According to the current experimental speed, if I want to make two batches of devices, it is estimated that it will be completed next Friday.

　　The key point is that Xu Qiu speculates that the advanced tasks are likely to be related to solar cell devices. If you want to pass the tasks, the evaporation operation is definitely indispensable.

　　 Then, can the system tell him the content of the advanced tasks in advance?

　　 In the process of getting along with the system these days, Xu Qiu found that the system would agree to most reasonable requests.

　　 Anyway, the worst thing is to be rejected by the system on the grounds of "insufficient authority level". You will never lose a try.

　　 "System, can you tell me advanced tasks in advance?"

　　 [You can get advanced missions from ~www.ltnovel.com~. Prepare solar cell devices of the benchmark system, and obtain a photoelectric conversion efficiency of more than 5%. Task reward: 2000 points, authority level +1. 】

　　 "Does the benchmark system refer to P3HT:PC[60]BM?"

【Yes. 】

　　 Xu Qiu learned from the literature that the highest international efficiency of this system has reached 5.6%.

　　 Is it a sub-question?

　　 Xu Qiu felt that it would definitely not be that simple, so he asked Chen Wanqing:

　　 "Sister, what is the highest efficiency of your P3HT:PC[60]BM device?"

　　 "4.5%," Chen Wanqing said.

　　 "Isn't it up to 5.6% in the literature?"

　　 "No way, others can do that high, I can't do it."

　　 "Aren't all the experimental conditions in the literature open to the public? It's not okay to follow their published methods?"

　　"It is difficult. Although the experimental procedures are written out, the specific details are not clear.

　　 Moreover, different research groups have different equipment and different experimental environments. It is very difficult to completely repeat the results of others.

　　 Therefore, the experimental methods of other research groups can only be used as reference. When conducting experiments on your own, you need to rely on continuous exploration and improvement of experimental operations.

　　 This 4.5% was also obtained after I optimized it many times. When I first came, I could only achieve less than 1%. "

"Ok."

　　 Sure enough, the advanced tasks of the system will not be so easy to complete.

　　 Fortunately, I stand on the shoulders of the senpai and can inherit 4.5% of her. I only need to work hard to increase it to more than 5%.
