Chapter 173: In this world, there will always be geniuses

"I have a scientific research support system ( to find the latest chapter!
Although the turning point of the speed did not appear, the turning point of the temperature has already appeared, from 110 degrees Celsius to 90 degrees Celsius, first rising and then falling, reaching the extreme value at 100 degrees Celsius.
Therefore, the 10.92% efficiency obtained under the condition of 3500 speed at 100 degrees Celsius may be the highest value today.
Of course, considering that only one piece is made for each condition, there are also abnormal situations caused by experimental operation reasons, such as the film is not coated well.
But this possibility is unlikely.
Since there is a high probability that the remaining components will not have higher performance, there is no need to watch the school girl test by the evaporation glove box.
Therefore, Xu Qiu decided to bugger.
He glanced at Chen Wanqing's direction. Senior sister's sample has been prepared, and now she is testing the light absorption spectrum, and the spin-coating glove box is empty.
The performance of the device is closely related to the solution. He plans to reconstitute the solution and try another batch of devices tomorrow.
Thinking of this, Xu Qiu patted the school the shoulder and said:
"You continue to test. I will prepare a solution. The remaining devices can be tested slightly faster. You don't have to scan the J-V curve so many times."
"Hmm~"
Xu Qiu always felt that her voice was different from usual, but he didn't care too much, turned around and went directly into the spin coating glove box.
During this period of time, he did relatively few experiments, and the occasional tests were all based on the characterization experiments performed by fool-like instruments.
It's been a long time since he has prepared the solution, and he feels a little handy.
Xu Qiu used tweezers to pick up the polymer material and weigh it.
Although he was already twelve points in spirit, he still accidentally dropped a small piece.
A rough estimate is that the small piece has five or six milligrams, which is equivalent to 10 milligrams of raw materials based on a 50% yield.
It seems to be only two or thirty yuan, not very expensive.
Comforting himself, he shook his head, picked up the fallen materials and threw them into the trash can. The organic polymer materials used in the laboratory have almost negligible toxicity. They are similar to plastics, so you can directly follow ordinary experiments. Room garbage disposal.
The small episode didn't affect Xu Qiu's mentality. After all, this kind of "hand birth" situation is also normal.
Even if it is Teacher Wei, he has 20 to 30 years of experimental experience, but let him do the experiment now, the level is estimated to be not as good as Chen Wanqing.
Moreover, with his current physical condition, it is difficult to conduct experiments on the front line for a long time.
His strength lies more in his understanding of scientific research itself, as well as his understanding of specific research directions, such as organic photovoltaics and perovskite materials.
In other words, the experience he has accumulated over the years in scientific research is his most valuable asset.
Because for experimental operations, although there are lower limits and thresholds, there are also upper limits.
According to the evaluation of the system, Xu Qiu speculated that to achieve the ultimate in an operation, the corresponding proficiency is level 6.
Like craftsmen, such as oil sellers, who do one thing for many years, the proficiency may be very close to the sixth level.
However, for the scientific research work itself, it is not necessary to repeat the experiment continuously to achieve a high level of proficiency. In most cases, the fourth to fifth level is sufficient.
More important is scientific research ideas.
Xu Qiu has seen news reports before, and a laboratory has developed a robot that can do experiments automatically.
They provide the robot with specified commands, and the robot can perform specific experimental operations, such as doing hundreds of parallel experiments at the same time.
And the robot is tireless and can work 23.5 hours a day.
Although the current level of intelligence of these robots is not high and the cost is high, they can only replace part of the experimental work, but with the continuous iteration of related technologies, their degree of intelligence will definitely become higher and higher.
In the end, it is not impossible to replace ordinary researchers with robots.
However, there is a problem, that is, for an experiment, in addition to the experimental results themselves, the experimental process is also very important.
In other words, even failed experiments are equally valuable, because many experimental discoveries are accidentally obtained from failed experiments.
Robots can complete experiments in batches, but they will also cause the lack of experimental information to a certain extent.
In the final analysis, robots only know how to execute commands, but do not have the ability to think, and they have no scientific research thinking or ideas.
...
The solution preparation is complete.
Xu Qiu copied the newly prepared solution, as well as the solution prepared by the school sisters and sisters recently, and the newly arrived spin coating equipment into the simulation laboratory.
Recently, the simulation laboratory has been sealed by him for a long time, because there has been no hard bones to chew, he plans to restart it tonight, and then rush to 11% efficiency in one fell swoop.
After the experiment, Xu Qiu, Chen Wanqing, and Han Jiaying gathered together to briefly discuss the progress of today's experiment.
In fact, in addition to the mandatory report of the group meeting once a week, the friends of the research group often gather together to discuss issues in twos and threes.
The scientific research atmosphere in the laboratory is still good.
Xu Qiu took the lead and said, "How about it, is there a miracle with a 90 degree Celsius device?"
Han Jiaying said: "No, the highest is 10.71%."
Xu Qiu nodded, he actually guessed the result, because in subsequent experiments, the school girl's performance has been very quiet, if she measured higher data, she would definitely not be so calm.
Han Jiaying continued: "Sister, the performance of the standard samples of your three systems are almost the same as the original ones, but the performance of the devices using the thermal spin coating method has decreased by 0.5-1% relative to the standard samples."
Chen Wanqing smashed her mouth and said helplessly: "As expected, consistent with the previous experimental results, it seems that the thermal spin coating method is not a universal and effective experimental method."
Xu Qiu asked: "Senior sister, how did you do the light absorption spectrum today?"
"Light absorption, the result is very good, the deviation of the spectral curve under different temperatures is very obvious," Chen Wanqing raised her eyebrows and said happily:
"Fortunately, with this new instrument, we can control the temperature very accurately. If we use the previous thermal spin coating method, the temperature obtained is actually very inaccurate. I personally feel that it is not convincing."
"That's true," Xu Qiu echoed: "After all, the film obtained by the previous method has a big circle in the center, and that is caused by uneven heating."
After a pause, Xu Qiu continued: "School girl, how are your two pieces measured?"
Han Jiaying said without hesitation: "Both films are maintained at about 6%, the highest of which is 6.80%, which is a slight improvement compared to before, but I estimate that according to today's results, continue to optimize the conditions, and the efficiency will most likely exceed 7. %."
"Yes, it is indeed very promising," Xu Qiu first complimented, then analyzed:
"I estimate that with this new thermal spin coating method, the actual temperature in the film formation process is higher than the previous thermal spin coating method. The higher the temperature, the faster the film formation and the thicker the film. Optimal conditions will shift to lower temperatures and higher speeds, which is also consistent with today’s experimental results."
"It makes sense." Senior sisters and senior sisters echoed the common way at the same time.
...
After the small meeting, it was almost ten o'clock in the evening, and Xu Qiu and Han Jiaying left the laboratory together.
It has entered winter, and the current outdoor temperature is within ten degrees Celsius. When he first came out of the door, he felt a little bit of chill.
There were three shared bicycles downstairs today, and the two picked one each.
Xu Qiu moved faster, unlocking the car, stepping onto the seat, and then looking at Han Jiaying from behind.
Under the street lamp, the school girl is dressed in black trousers and a beige fluffy coat, her whole body wrapped tightly.
She blew herself up to height 163, but Xu Qiu suspected that she was wearing shoes with increased height.
The weight is not 100% visually. When I patted her on the shoulder today, I felt that there was not much meat, it was all bones.
Of course, it may also be related to the location of the shot.
The school girl was not riding fast, and Xu Qiu also slowed down.
At this time, there were no more vehicles on the road from the headquarters to the southern dormitory, and the two were riding side by side.
"Unconsciously, a semester is almost over." Han Jiaying took the lead.
"Yeah, time flies so fast."
"Brother, how did you achieve such a powerful scientific research?"
Xu Qiu was taken aback, how should I answer this?
I can’t say that I have a system~EbookFREE.me~ He thought about it and said casually:
"In this world, there will always be geniuses."
"I also think Brother is a genius."
"The school girl is not bad."
"Hey, yes."
...
Back in the bedroom, Xu Qiu greeted her roommate and took a cold shower in the corridor.
I have to say that the taste of taking a shower in winter is quite unique.
It was a bit difficult at the beginning, but as long as you survive the first minute, you will feel much better afterwards, and your whole body will be very warm after washing.
After the shower, Xu Qiu lay on the bed and entered the simulation laboratory.
I haven't used this function for a while, and the system points can only be accessed for a long time.
At present, his points have accumulated to more than 3W, which is enough for him not to accelerate and conduct more than 300 hours of experiments.
In the current simulation laboratory, in addition to the super large laboratory such as Magic Light Source, other characterization laboratories are already prepared.
He has backed up several common laboratories such as Caiyi 216 and Microelectronics Building A502.
I just don't know when I can complete the advanced task. Now I am applying for this job in AM, even if I am rejected or transferred to other journals, an SCI area will definitely not run.
It is a pity that there is no news so far, which is still quite depressing.
He checked the MEDSCI website, and the average review time for AM was 1.33 months.
Some people in the comments only spent more than 20 days, and there were more than a month, or even two months, but I did not see any more than three months.
Although he is very confident in his article, but there has been no news, it is inevitable that he will suffer from gains and losses.
Xu Qiu shook his head, eliminated all the messy thoughts in his mind, and concentrated on preparing for the experiment.
