Chapter 899 "High efficiency"
Looking at this battle report, Gao Zhendong completely put down a big stone in his heart.
Stable!
He knew that this thing was a big killer for armor torrents, but he was not sure if this was done by him, because he had not been tested by actual combat.
With this battle report, in the next few decades, the biggest threat to conventional land forces can almost be said to be completely eliminated.
As for whether the Russians would pick up the debris from the Sand, Gao Zhendong was not worried at all. The Russians' problems could not be solved by picking up a broken copper and iron. They were here many times in their previous life. The above thought about it, but the result was not very good.
Although it was made in name, at least they had never seen this thing when the two brothers fought.
The anti-tank missiles in front are difficult to fight at the battle level, but the final agile missiles can do so. Moreover, compared with second-generation tanks, equipment that can also be used at the battle level, it is easier to reach the scale of the final aggressor, more convenient to use, and less expensive.
He put down the battle report and made a call in a happy mood.
"Well, I have time now, come here."
Within a few minutes, Tang Shaohui brought the core backbone of the team to him and they also had two finished solar panels, with dark and deep silicon wafers on them.
"Mr. Gao, it's done! The photoelectric efficiency of monocrystalline silicon is 20.3%, and the photoelectric efficiency of polycrystalline silicon is 17.1%!"
For Tang Shaohui and others, 1274 has strong support in semiconductor processes There are a series of advanced production equipment created by Gao Zhendong and 1274, which makes them the biggest trouble. Instead, in the production of silicon wafer suede. When the problem of velvet is solved, other problems later become Just a trial and error process.
And Chief Engineer Gao has helped him get rid of many wrong answers and single-choice questions, but he is allowed to do it a few more times, so how can he still fail to achieve results?
It is hard to say that mass production is now, especially monocrystalline silicon photovoltaic panels, but at least polycrystalline silicon is no problem. The hydrogen peroxide triple-connected that was improved with the help of Chief Engineer Gao, accidentally discovered by the team. The process is really great for making velvets on polysilicon panels.
Don’t underestimate the step of velvet making. Many solar panels in later generations are called "suede X-crystalline silicon solar cells". The importance of being able to add the name to the full name is evident.
Tang Shaohui's words were proud, which was an extremely important achievement for them. He even never thought that he could achieve this level of achievement.
As senior technicians who have been working on solar cells for a long time, they are familiar with domestic and foreign literature and are very clear about what these two photoelectric conversion efficiency represent.
Gao Zhendong was also a little surprised when he heard this. Although he knew that the height that monocrystalline silicon and polycrystalline silicon could reach in the future was much higher than the data that Tang Shaohui said, what era was that and how much investment was there? ?
It can be said that even with the technical support provided by itself, Tang Shaohui and the others will work hard and make great contributions.
"Okay! Great! You have exceeded the task, hahaha."
Originally, under the guidance of the Defense Work Committee, the goal was 12% monocrystalline silicon, but Gao Zhendong thought to himself The one is 15% single crystal silicon. As for polycrystalline silicon, it was not considered at all at the time, and it was added only at the suggestion of Tang Shaohui. "How about other performances? Especially in attenuation." Gao Zhendong thought for a while and could not drive champagne in half, so calm down.
"It has been done and it fully meets the requirements. The attenuation of monocrystalline silicon under irradiation conditions is also fully satisfied." Tang Shaohui knew that Gao Zhendong attaches great importance to this aspect, so he made preparations early and made full arrangements. The test was done so completely.
"Okay!" Gao Zhendong had no doubts: "How is the maturity of the process?"
When Tang Shaohui heard this, he felt a little embarrassed. It's right...
"Polycrystalline silicon has no problem, it has the ability to mass produce, and it's monocrystalline silicon... It's a bit like a laboratory product, mainly for conversion efficiency. The requirements are very high, so many process links are strictly controlled, resulting in no problem with product performance, but the cost is very high. "It has a bit disappointed General Gao's expectations.
I didn't expect Gao Zhendong to care about it at all and was very happy: "Hahaha, good job! Good job!"
The so-called laboratory products are not mass-produced and promoted. There are many types of laboratory products.
Theoretically, it works, but the performance is unstable or the duration is short, so don’t consider the cost, etc. This is one.
The theory is done and the state can be stabilized, but only the main indicators are realized, and the other indicators are very poor. This is one.
There is no problem with the theory, the state is stable, and the various parameter indicators are qualified, but the mass production conditions are not met, such as scarce raw materials, high costs, and the main production equipment is limited by other conditions...
Which Tang Shaohui What I mean is the last one, and it is the most acceptable "high cost".
It is too expensive to be a big deal compared to problems such as not finding materials or not having equipment. It's too expensive but it can't be used in large quantities, while in other cases it's whether it's useful. The difference between 1 and 0 is very big at some point.
Moreover, the situation is even more special when it comes to these two solar panels.
"Single crystal silicon is expensive, and if you want to spread it, it is not affordable. For special purposes, as long as you achieve the premise of stability and compliance with the index parameters, you can prepare a little in the laboratory. A large number of laying The ones that are used are polysilicon, and this energy production is enough at this stage."
Seeing that Tang Shaohui was still a little embarrassed, Gao Zhendong took the initiative to explain, the meaning is very clear, you don’t need it. Worry, you have done well enough to fully meet the project requirements, and it is greatly exceeded.
Originally, Gao Zhendong was thinking of getting some monocrystalline silicon for use for satellites, and then taking into account a few remote areas with extremely inconvenient transportation. Unexpectedly, with the efforts of Tang Shaohui, the new force, he could even be It has been barely popularized and used. Although it is incomparable to the popularization of later generations, it is at least a big step forward compared to Gao Zhendong's original idea.
After saying that, he patted Tang Shaohui on the shoulder: "Make a science and technology briefing, I'll report it and prepare for an acceptance meeting."
The next morning, the relevant comrades in charge of the satellite power supply system received a notice from the Defense Work Committee.
Looking at the content of the notification, he laughed.
"At 2:00 p.m. on X, X, at 2:00 p.m., the High-Efficiency Solar Panel Results Acceptance Appraisal Meeting was held in the X Conference Room of the Defense Work Committee. Please be sure to attend the comrades in your unit."
The solar panels are ready? Since the Defense Working Committee has added the three words "high efficiency" to the name of the appraisal meeting, I think this thing is not bad.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
Looking at the days, it was this afternoon. He hurried to the head of the unit to ask for leave. As the core backbone of this area, no matter where he goes during working hours, he had to say hello to the leader first.
The unit leader is happier than him. If this matter is solved, it means that it will be one step further from the practical satellite to the sky.
"Go and go, bring some good news back."
"It must be good news. The matter led by the Defense Work Committee is still relatively reliable." Although I didn't see the specific one The results are content, but this comrade is very confident. I remember that the Defense Working Committee handed over this matter to one of the most powerful scientific research forces in this regard.
Gao Zhendong said that he was second in optoelectronics, and it was really hard to find someone who dared to be the first.
In the afternoon, there were not many people in the conference room of the solar panel achievement appraisal meeting of the Defense Work Committee. The 17th Ministry of Machinery, the Defense Work Committee, and the 12th Ministry of Machinery have all come. The others are the most clear except for satellite power supply. There are not many users outside of them, mainly experts in some related fields.
But there was a group of participants who came very interesting. They heard that this happened, and they were related to Gao Zhendong. They came. They were also very humble when they came. We just listen to it, learn and learn. Not much nonsense.
These people are representatives of the permanent defense committee. Now they are very interested in any meetings that Gao Zhendong participated. Even if they have nothing to do with them, what if they can find something new ?
The army is especially good, which is one of the most beautiful kids from the army. Even if there is nothing to do, it’s okay to support him.
The participants who didn't know much about the situation were stunned when they got the report materials. The responsible unit was in a strange mood.
Collaborative units, 1761, 1274, 1274, and 12th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 20th, 2
Main unit, the third steel rolling mill of the 17th Ministry of Machinery.
Any of the first two units is normal as the main unit. One is responsible for the theoretical research of semiconductors and crystals, and the other is responsible for semiconductor process production. There is nothing wrong with it, and even the research institute of the Ministry of Chemical Technology is barely suitable.
But these three units cooperate, and the main units are the third steel rolling mill that seems to be inseparable from solar panels.
It's against Tiangang.
However, those who know the knowledge know that it seems that today's matter is stable!
The results appraisal and acceptance do not mean that it is certain to pass, but today is almost certain. Look at Gao Zhendong, who is smiling in the report seat, needless to say, this is another happy day.
A new achievement is about to be born, but how can it be unpleasant?
And this will most likely not be quarrels, and it will be comfortable to drive.
The comrades who were engaged in satellite power supply couldn't wait to turn the materials to the parameter page.
"Damn it!!! Impossible??!!" Even though he is very educated, he couldn't help but use a slap in the world.
The few numbers in the parameter table are so eye-catching!
Polysilicon, which had not been considered at all, appeared here, and its efficiency was as high as 17.1%.
As for the other original protagonist, it is even more exaggerated, more than 20%! ! ! !
