Siheyuan: Originally I just wanted to be a little transparent

Because the information Lin Shengli copied about photovoltaic materials and solar power generation technology only copied some relatively important ones, not all of them.

The information to be submitted to the above must be complete and comprehensive.

Although Lin Shengli made a mechanical typewriter by hand, Lin Shengli still had to draw the corresponding technical drawings by hand!

After arriving at the laboratory, Lin Shengli thought about which type of solar cell he should choose this time. In the end, after careful consideration, Lin Shengli chose the monocrystalline silicon solar cell.

Although the overall cost of this kind of monocrystalline silicon solar cell will be higher, it cannot be used for large-scale solar power generation as it was in later generations.

However, this kind of monocrystalline silicon solar cell is currently the best thing that Lin Shengli can produce based on the existing equipment and materials at hand.

Moreover, it is only used on satellites on a small scale as solar panels, and the slightly higher cost is basically negligible.

After selecting the specific items to be manufactured, Lin Shengli recalled the technical information about this monocrystalline silicon solar cell in his mind.

Soon, Lin Shengli made a specific list of materials based on the technical information in his mind and handed it over to the comrade in charge of procurement on the project.

This had strong support from superiors. The comrades in charge of procurement at the institute were very efficient. It didn't take long for the materials listed by Lin Shengli to be sent over.

In the days that followed, apart from his normal work, Lin Shengli spent most of his time in the materials laboratory.

In the end, all the hard work paid off. More than a month later, Lin Shengli finally produced the first solar panel.

In fact, Lin Shengli could have been faster, but after all, he had other things to be busy with. In addition, this time, he was also deliberately guiding the scientific researchers in the laboratory so that they could be more involved in the R&D and manufacturing process. Come.

It was a sunny noon, perfect for testing solar cells.

When he learned that Lin Shengli was going to conduct solar cell experiments today, Team Leader Sun ran over immediately, and then Dean Qian, who learned the news, also hurried over from the research institute.

In later generations, solar power generation was already a relatively popular power generation technology.

Even a sun hat with a fan can be equipped with a solar panel.

But in this day and age, this solar cell is a rare thing.

Moreover, the success or failure of this solar cell is directly related to the entire satellite project.

If this fails, the military satellite plan will probably have to die.

"Shengli, you have built a solar cell so quickly, there won't be any problems, right?"

Although Lin Shengli has slowed down the production speed, in Dean Qian's opinion, how long has it been until this happened?
You must know that solar cells now represent very advanced high-tech gadgets internationally.

Although Dean Qian also believed very much and was optimistic about Lin Shengli's miraculous power, Lin Shengli was able to do it so easily in such a short period of time, which inevitably made Dean Qian a little worried.

Lin Shengli smiled and said: "I think it's okay. It shouldn't be a big problem, but the specific performance needs to be tested for a while."

After Lin Shengli finished speaking, Team Leader Sun, who was standing aside, said confidently: "Dean Qian, you can rest assured. Our Comrade Shengli has never fought a battle that was uncertain."

"With the solid motors before this, especially our launch vehicle project, who would have thought that if the final facts hadn't been there, we would be able to develop a launch vehicle with a flight thrust of [-] tons and a carrying capacity of more than [-] tons in one fell swoop. Come."

After listening to Team Leader Sun's words, Dean Qian thought about it and realized that it was indeed the case.

Whatever Lin Shengli takes over, there is really nothing he can't do.

Especially if that sentence is okay, then the matter is basically settled!

"Shengli, when will we start the experiment?" Dean Qian asked, looking at Lin Shengli who was standing there a little unhurriedly.

Lin Shengli raised his head and glanced at the sun, and then said: "It will take a while. We will start when the comrades have connected all the equipment."

After listening to Lin Shengli's words, Dean Qian noticed that the comrades in the laboratory were constantly moving things to the open space where they were and busy assembling wiring.

After a while, a complete solar power generation device was assembled on this vacant land.

A laboratory staff member came over and said to Lin Shengli: "Report to Consultant Lin that the solar equipment has been installed, the testing equipment has been connected, and the experiment can be started at any time."

Seeing that the preparations were ready, Lin Shengli said to Dean Qian and Team Leader Sun on the side: "Dean Qian and Team Leader Sun, the preparations are almost done. We have to go into the laboratory. This is for The testing equipment is all connected in the laboratory.”

Hearing this, the two people who were very curious about solar cells nodded and followed Lin Shengli to the laboratory separated by a wall.

At this time, the two of them also wanted to know whether the solar cell developed by Lin Shengli could be successful, and if so, to what extent could it be achieved?
"Comrades, after more than a month of hard work, we have finally completed this set of solar power generation equipment. It is time to test the results of our labor soon..." "Comrades from all positions please pay attention and observe and record, okay, now let’s start testing.”

Following Lin Shengli's order, the experimental researchers got into their positions and began to test the solar equipment.

When the line was connected, a series of data immediately appeared on the test equipment in the laboratory.

After a while, Lin Shengli got the summarized experimental data.

Lin Shengli looked at the data record in his hand, smiled and said to the two people around him: "Dean Qian and Team Leader Sun, our solar cell project is finally completed."

"Based on data calculations, the photoelectric conversion efficiency of the monocrystalline silicon solar cell we developed is as high as 23%, which is almost the conversion limit that this photovoltaic material can achieve."

After hearing what Lin Shengli said, Dean Qian and Team Leader Sun were very happy. They pulled Lin Shengli and walked outside. They couldn't wait to see this solar cell.

After arriving at the open space where the solar device was installed, Lin Shengli pointed to the equipment in front of him and said: "You two, this is our solar cell."

"For this solar cell, we mainly use monocrystalline silicon, and then we also use tempered glass and sealing resin to encapsulate it."

"This will make our solar panels more sturdy and durable."

"If there is no external damage, the theoretical service life of this solar panel can be at least 20 years."

"Great, Comrade Shengli, now that our solar panels have been successfully developed, can they be directly used on our military satellites?" Team Leader Sun asked excitedly.

Lin Shengli smiled and said: "Team Leader Sun, what we see now is only part of this complete set of solar power generation equipment."

"There are still some corresponding supporting equipment that have not been installed. After all are installed, it will be a complete solar power generation device."

"However, the other supporting equipment is relatively simple and can be manufactured quickly. It only needs to be installed and debugged."

After hearing what Lin Shengli said, Dean Qian and Team Leader Sun were both overjoyed.

Now that Lin Shengli's solar cell is successful, their military satellite project can be said to be half successful!
A complete solar photovoltaic power generation system consists of solar cell components, controllers, batteries, inverters, user power loads, etc.

After solving the most important problem of solar panels, the rest is relatively simple.

Nowadays, because the military satellite has not yet entered the final assembly stage, the solar power generation device developed by Lin Shengli cannot be formally load tested.

However, as long as the assembly of the satellite is completed, the solar device developed by Lin Shengli can be put on the machine for testing at any time.

As the days passed, Lin Shengli's follow-up work was quickly completed.

Since Lin Shengli tested the solar panels last time, the dean has never been to the materials laboratory located in the steel rolling mill.

In fact, it's not that Dean Qian doesn't pay attention to this, but that he has learned from Lin Shengli that the remaining tasks are relatively simple tasks. He believes that with Lin Shengli's ability, it will be nothing if done. questionable.

Therefore, Dean Qian was very relieved and left it entirely to Lin Shengli. He didn't act like a supervisor and would go over to take a look from time to time.

No matter how you say it, Lin Shengli is engaged in the satellite project, and the dean is also his superior. If the leader doesn't take the initiative to ask, he will take the initiative to report.

No, Lin Shengli ran to Dean Qian to report.

"Shengli, how are you doing over there?"

As soon as Lin Shengli entered the door, Dean Qian asked.

Lin Shengli smiled and said: "Dean Qian, the follow-up work of this solar cell project has been completed."

"We have also conducted corresponding simulated load tests. Now when our military satellite is undergoing final assembly, we can install the solar equipment and conduct a formal satellite live load test."

"And my current focus has shifted to military satellites."

After listening to Lin Shengli's words, Dean Qian smiled and said, "Comrade Shengli, this is really good news."

"You have made another great contribution to our aerospace industry!"

Hearing this, Lin Shengli shook his head and said: "This is all our job. There is no meritorious service."

"Dean, I'm here today. In addition to reporting on the recent progress of my work, I also have something I want to discuss with you." (End of Chapter)
