I Have a Research Support System

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

Xu Qiu ordered an old duck vermicelli soup and a basket of Jinling steamed buns; Chen Wanqing ordered a plate of meat, two vegetables and two taels of rice; Tian Qing ordered a fried rice noodle with small ribs; The hot pot is steaming and spicy, and it comes with two bowls of rice.

While eating, chatting about campus gossip.

My roommate is in He Xilan's group, he is miserable. Duan Yun shared enthusiastically:

Yesterday afternoon, He Xilan told them that she was busy and would not come tonight.

So, the five people in their research group let themselves go, and played the League of Kings in the laboratory.

However, at eight o'clock in the evening, He Xilan went back to the laboratory to kill them and caught them straight.

In the end, all five people were fined to criticize themselves for five minutes at the group meeting and then write a self-criticism.

This is fishing law enforcement, Tian Qing said:

Besides, He Xilan has a bad temper and often insults students. Her reputation has spread throughout the Materials Department.

The students she recruited in recent years are basically from other schools, and everyone in this school knows how she is, so no one dares to go.

It is said that there was a master student last year who went to her group for half a year and 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 in Neon Country, and the other was three years ago. In our school, one of her Ph.D. of.

Therefore, there are still many students who seek her as a tutor every year.

Tian Qing suddenly lowered her voice and said, It is said that there seems to be a relationship between her and Teacher Wei...

Others stopped their chopsticks when they heard the gossip.

Tian Qing continued: It seems that they used to be roommates.

Duan Yun: Roommates? Really, they can still be roommates if they are a man and a woman.

Tian Qing: When we were studying abroad, we rented together.

Duan Yun: How do you know about this kind of thing?

Tian Qing: Well... I heard what my classmate said, and she said that she also heard what her classmate said.

Duan Yun: It turned out to be gossip.

Xu Qiu was eating melons quietly beside him, feeling in his heart that the daily chatting of graduate students is really inseparable from the tutor.

…………

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

Xu Qiu went to the main control console to check, the vacuum gauge reads 8.9E-5 Pa, and the molecular pump rotates at 27000r.p.m., everything is normal, and the experiment can be continued.

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

Then adjust the heating program and start the program.

SP1 400

RATE 30

TIME 3

SP2 560

RATE 20

TIME 100

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

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

After more than an hour, no accident happened.

Xu Qiu obtained 10 evaporated substrates, took them out, and put them into petri dishes.

Then, he opened the system interface:

【Scientific Research Auxiliary System】

Privilege Level: 1

Points: 978

Tasks in progress: 1

Proficiency:

【Experimental operation class】

Clean the substrate (fourth stage 20%/fourth stage 50%, require ultrasonic cleaner, tweezers, nitrogen gun)

Solution preparation (fourth stage 10%/fourth stage 50%, glove box, heating and stirring table, disposable syringe, medicine spoon, pipette gun are required)

Spin coating (fourth stage 0%/fourth stage 50%, requires ozone generator, glue homogenizer, disposable syringe, tweezers, pipette gun, heating and stirring table)

Evaporation (third stage 0%/fourth stage 50%, requires glove box, evaporation equipment)

【Instrument Equipment Tools】

...

【Special class】

Literature reading (Level 94%/Level 50%)

Novice task V: Improve the proficiency of any four experimental operations to level 4 or above, reward 1000 points for completing the task, and open the advanced task.

##

Seeing that there was only 0% vapor deposition proficiency in the third level, Xu Qiu felt a little headache.

If you want to master this proficiency, you have to make solar cell devices, and you have to do it from scratch. You can't use empty substrates for evaporation.

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

It's okay, I'm fine, I was thinking just now, can vacuum coating be used to evaporate other things. Xu Qiu said.

Other things... Chen Wanqing thought for a while, and said, Yes, we used gold as electrodes to prepare battery devices before. When evaporating gold, we put a few round iron sheets in the cabin by the way, and after the end Take it out and it’s a gold coin, but it’s 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 upgrade to the fourth level, 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 you want to make two batches of devices, it is estimated that it will not be completed until next Friday.

The key point is that Xu Qiu speculates that the advanced task is likely to be related to the solar cell device. To pass the task, the evaporation operation must be indispensable.

So, can the system tell him the advanced task content in advance?

In the process of getting along with the system in the past few 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, so you won't lose money if you try it.

System, can you inform me of advanced tasks in advance?

【Can. 】

[Get advanced tasks. A benchmark system solar cell device was prepared, and a photoelectric conversion efficiency of more than 5% was obtained. Task reward: 2000 points, permission level +1. 】

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

【Yes. 】

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

Is it a sub-question?

Xu Qiu felt that it was definitely not that simple, so she asked Chen Wanqing:

Sister, what is the highest efficiency you can achieve with P3HT:PC[60]BM devices?

4.5%. Chen Wanqing said.

Isn't the highest in the literature up to 5.6%?

No, hey, other people can do so high, I can't do it.

Aren't all the experimental conditions published in the literature now, and it's okay to do it completely according to the methods they announced?

It's very difficult, although the experimental steps are written out, but the specific details are not clear.

Moreover, different research groups have different equipment and different experimental environments, so it is very difficult to completely replicate other people's results.

Therefore, the experimental methods of other research groups can only be used as a reference. When conducting experiments by oneself, it is necessary to rely on continuous exploration and improvement of experimental operations.

This 4.5% is also obtained by my optimization many times. When I first came here, I could only achieve less than 1%.

All right.

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

Fortunately, I stand on the shoulders of my senior sister and can inherit her 4.5%. I just need to work harder to increase it to more than 5%.
