I Have a Research Support System

Although the inflection point of the speed has not appeared, the inflection point of the temperature has appeared, from 110 degrees Celsius to 90 degrees Celsius, it rises first and then decreases, and reaches the extreme value at 100 degrees Celsius.

Therefore, under the condition of 100 degrees Celsius and 3500 rpm, the efficiency of 10.92% may be the highest value today.

Of course, considering that only one piece was made for each condition, there are also abnormalities caused by experimental operation reasons, such as the film not being coated properly.

But this possibility is not great.

Since there is a high probability that the remaining devices will not have higher performance, there is no need to watch the school girl test by the evaporation glove box.

So, Xu Qiu decided to run away.

He glanced at Chen Wanqing's direction. The senior sister's sample had been prepared, and now she was testing the light absorption spectrum, and the spin-coating glove box was emptied.

The performance of the device is closely related to the solution, so he plans to reconstitute the solution and try another batch of devices tomorrow.

Thinking of this, Xu Qiu patted Xuemei on the shoulder and said:

Go ahead and test. I'll prepare a solution. The rest of the devices can be tested a little faster, and the number of times to scan the J-V curve doesn't need to be so many.

Hmm~

Xu Qiu always felt that her voice was different from usual, but he didn't pay too much attention to it, 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 he did were all characterization experiments based on fool-like instruments.

It has been a long time since the solution was prepared, and he felt a little unfamiliar.

Xu Qiu weighed the polymer material with tweezers.

Although he had put all his energy into it, he still accidentally dropped a small piece.

It is roughly estimated 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 twenty or thirty yuan, which is not very expensive.

After 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 they can be directly used in ordinary experiments. Room garbage disposal.

The small episode did not affect Xu Qiu's mentality, after all, this kind of hands-on situation is also normal.

Even Teacher Wei, who has 20 to 30 years of experience in experiments, can let him do experiments now, and his level is probably not as good as that of Chen Wanqing.

Moreover, with his current physical condition, it is difficult to do experiments on the front line for a long time.

His advantage lies more in his understanding of the scientific research work 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 is a lower limit and a threshold, there is also an upper limit.

According to the system's evaluation, Xu Qiu guessed that to achieve the ultimate in an operation, the corresponding level of proficiency is level six.

For craftsmen, such as oil sellers, who have been doing one thing for many years, their proficiency may be very close to the sixth level.

But for the scientific research itself, it is not necessary to repeat the experiment continuously to increase the level of proficiency. In most cases, the fourth to fifth level is enough.

What is more important is scientific research ideas.

Xu Qiu had seen news reports before that a robot that could do experiments automatically had been developed by a laboratory.

They provide the robot with specified commands, so that the robot can perform specific experimental operations, such as doing hundreds of parallel experiments at the same time.

Moreover, the robot is tireless and can work 23.5 hours a day.

Although the intelligence level of these robots is not high at present and the cost is high, they can only replace part of the experimental work, but with the continuous iteration of related technologies, their intelligence level will definitely become higher and higher.

In the end, it is not impossible to partially replace ordinary scientific 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 obtained by accident from failed experiments.

The robot can complete experiments in batches, but it 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, scientific thinking and ideas.

...

Solution preparation is complete.

Xu Qiu copied the newly prepared solution, the solution prepared by his seniors 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 bone to gnaw, he plans to restart it tonight, and then rush to 11% efficiency in one fell swoop.

After the experiment was over, Xu Qiu, Chen Wanqing, and Han Jiaying got 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 small partners of the research group often get together in twos and threes to discuss issues.

The research atmosphere in the laboratory is good.

Xu Qiu took the lead and said, How about it, is there any miracle for the 90-degree Celsius device?

Han Jiaying said: No, the maximum is 10.71%.

Xu Qiu nodded. He actually guessed this result, because in the subsequent experiments, the junior girl's performance has been very quiet. If she had measured higher data, she would definitely not be so calm.

Han Jiaying continued: Sister, the performance of the standard sample of your three systems is similar to the original one, but the performance of the device using the thermal spin coating method has dropped by 0.5-1% compared to the standard sample.

Chen Wanqing smacked her mouth and said helplessly, As expected, it is 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 are you doing in light absorption spectroscopy today?

Light absorption, the result is very good, the shift of the spectral curve is very obvious at different temperatures, 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 think it is not convincing.

That's true, Xu Qiu echoed, After all, the film obtained by the previous method has a large circle in the center, which is caused by uneven heating.

After a pause, Xu Qiu continued: Sister, how are your two pieces tested?

Han Jiaying said without hesitation: The two slices are maintained at around 6%, and the highest one is 6.80%. Compared with before, it is slightly improved, but I estimate that according to today's results, if we continue to optimize the conditions, the efficiency will probably break through 7%. %.

That's right, it's really promising, Xu Qiu praised first, and then analyzed:

I estimate that the actual temperature during the film formation process of this new thermal spin coating method is higher than that of the previous thermal spin coating method, and the higher the temperature, the faster the film formation and the thicker the film, so the best The optimal conditions will shift to lower temperature and higher rotational speed, which is also consistent with today's experimental results.

It makes sense. The seniors and the juniors agreed at the same time.

...

After the small meeting, it was almost ten o'clock in the evening, Xu Qiu and Han Jiaying left the laboratory together.

It's already winter, and the current outdoor temperature is within ten degrees Celsius. When he first came out of the gate, he felt a little cold.

Today, there are three shared bicycles downstairs, and the two of them each picked one.

Xu Qiu moved faster, unlocked the car, stepped on the seat, and looked at Han Jiaying from behind.

Under the street lamp, the school girl was wearing black trousers and a beige fluffy jacket, and her whole body was tightly wrapped.

She claimed to be 163 in height, but Xu Qiu suspected that she was wearing height-enhancing shoes.

The weight is less than 100 by visual inspection. When I patted her on the shoulder today, I felt that there was not much meat, but bones.

Of course, it may also have something to do with the location of the shot.

The junior girl was not riding fast, so Xu Qiu also slowed down.

At this point in time, there were no vehicles on the road from the headquarters to the dormitory in the southern district, and the two rode side by side.

Before you know it, the semester is almost over. Han Jiaying spoke first.

Yeah, time flies by so fast.

Brother, you are so good at scientific research, how did you do it?

Xu Qiu was taken aback, how should I answer this?

You can't say that you have a system, right? He thought about it and said casually:

In this world, there will always be geniuses.

I also think that brother is a genius.

The school girl is not bad either.

Hey, yeah.

...

Back in the dormitory, Xu Qiu greeted his roommates and went to the corridor to take a cold shower.

I have to say that the taste of taking a cold bath in winter is quite unique.

It was tough at first, but as long as you get through the first minute, you will feel much better after that, and you will be very warm after washing.

After taking a 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 entered and not withdrawn for a long time.

At present, his points have accumulated more than 30,000 points, which is enough for him to conduct more than 300 hours of experiments without accelerating.

In the current simulation laboratory, except for the super-large laboratory such as Modu Light Source, other various characterization laboratories have been fully prepared.

He has backed up several commonly used laboratories such as Caiyi 216 and Microelectronics Building A502.

I just don’t know when I will be able to complete the advanced task. Now I am applying for the job of AM, even if I am rejected or transferred to other journals, I will definitely not run an article in the first section of SCI.

It's a pity that there is no news so far, which is quite depressing.

He checked the MEDSCI website, and the average review time for AM is 1.33 months.

Some people in the comments only used it for more than 20 days, and some people used it for more than a month, or even two months, but I didn't see anyone who used it for more than three months.

Although he is very confident in his article, but there has been no news, it is inevitable that he will worry about gains and losses.

Xu Qiu shook his head, got rid of these messy thoughts in his mind, and concentrated on preparing for the experiment.
