Hand rubbing nuclear fusion live in the wilderness

Chapter 291 Really Change the World

At this moment, the eyes of the whole world are on this magical live broadcast room.

If you can learn ultra-high-efficiency photoelectric conversion technology, the development of human science and technology will take off again!

The 'high-efficiency solar power generation panel' is different from the previous 'lithium-sulfur battery' and 'electric propulsion-no working fluid engine'.

One of the latter two is mainly to change the technology of electrical appliances, automobiles, etc., and the other is to change the aerospace aspects of the earth.

But 'high-efficiency solar panels' are different. Its appearance does not change one side, but the kind that takes off in an all-round way.

The problem of energy supply is solved, whether it is small in every aspect of life or in the environment of the earth, it will change accordingly.

As far as Huaguo is concerned, when solar power generation can replace thermal power generation as the main power supply method.

The changes brought about will be enormous.

When large-scale photovoltaic farms are built in the Northwest, oil will take a large part of its properties from motor fuel.

The Strait of Malacca, the Strait of Hormuz and other places will no longer be strategic areas to contain China.

Because over time, electricity will gradually replace petroleum fuels.

And if petroleum is only used as a raw material for industrial production, the required amount will be greatly reduced.

Huaguo can even achieve self-sufficiency.

Of course, the realization of all this will take time.

Even with Huaguo's powerful mobilization ability and crazy construction ability, it is not something that can be completed within three to five years if he wants to build an extremely large photovoltaic power field in the northwest region that can supply the whole country.

"Maybe by that time, I have already obtained the scientific and technological information of controllable nuclear fusion?"

Standing in the chemical laboratory, Han Yuan thought quietly.

When his thoughts slowed down a bit, Han Yuan withdrew his attention.

Seeing the sharp increase in the number of people and the frenzied barrage in the live broadcast room, Han Yuan smiled and said:
"Using solar panels to supply flight power is a very normal thing, just as primitive satellites use photovoltaic panels to supply energy."

"The solar panel I will use this time is one of the silicon-based solar panels."

"Its full name is 'lanthanum gallium silicon thin film solar thin film power generation panel'."

"It is a thin film based on crystalline silicon, in which a special lanthanide gallium crystalline ion structure is vapor-deposited."

"This silicon solar thin film with a special lanthanum gallium crystalline ion structure can achieve a photoelectric conversion efficiency of about 70.00% for a monolithic thin film."

"Of course, the photoelectric conversion efficiency will be affected by environmental conditions such as sunlight intensity and temperature."

"Theoretically, when the irradiation intensity is 1000M/cm2 and the solar operating temperature is 25°C±2°C, the photoelectric conversion rate of this 'lanthanum gallium silicon thin film solar thin film power generation panel' can reach the highest point, 73.41%."

After Han Yuan's voice fell, the discussion started again in the live broadcast room.

[70% photoelectric conversion rate! 】

[Awesome, this is really awesome. I remember that the photoelectric conversion rate of commercial solar panels is less than 20.00%, right?It has doubled by 3.5 times. 】

[The conversion rate is 70.00%, is this one square meter power generation panel enough for the daily use of a family?No wonder the anchor said that it can be used to provide power to the aircraft. 】

[Only 70.00% conversion rate?so low? 】

[Those upstairs, your news is long outdated. In June this year, the United States developed a solar cell with a photoelectric conversion rate as high as 60.00%. 】

【? ? ? ? ? ? 】

[What is this situation?Some said it was high, and some said it was low. Is the conversion rate of 70.00% low or high? 】

【high! 】

【Low! 】

[If you already have solar panels with a conversion rate of 60.00%, then 70.00% is indeed not a high feeling. 】

[In rural areas, photovoltaic power generation is a scam. Some fraudulent companies use the free installation of photovoltaic power generation equipment to provide free power supply to defraud farmers of their hard-earned money. 】

[Solar power generation is rubbish, okay? No matter how efficient it is, it can’t generate a few kilowatt-hours of electricity in a day. 】

[Then why is the whole world vigorously developing solar power generation? 】

[Is there any knowledgeable talk about it? You guys are very happy to talk about it, but it's not convincing at all. 】

[The photoelectric conversion rate of 70.00% is actually very high, but this amount of power generation is far from enough for an aircraft, and it cannot solve the power supply problem of the aircraft at all. 】

In the live broadcast room, the audience talked a lot, and everyone was a little confused about the solar power generation panel with a photoelectric conversion rate of 70.00%.

Some feel low, some feel high.

These are normal, ordinary people under normal circumstances, who would be free to understand these things.

Many people often receive this information from various outdated news.

Even experts from various industries squatting in the live broadcast room may not be very clear about the photoelectric conversion efficiency of the cutting-edge solar power panels in the international community.

After all, experts are not omnipotent, not a professional, unless there is some popular technology, otherwise it is normal to be unclear.

However, even if they don't know what kind of cutting-edge technology can reach, these experts still understand things like photoelectric conversion efficiency.

This is high school physics stuff, everyone has it.

The photoelectric conversion efficiency of 70.00% is indeed very high.

Putting it into the current human society, if it can be mass-produced, it belongs to the proper level of black technology.

But as some knowledgeable viewers in the live broadcast room said.

The photoelectric conversion rate of 70.00% is a bit too low if it is put on an aircraft to supply power to an aircraft that consumes a lot of energy?
This is also something that these experts can't figure out, after all, they are not experts in this field.

Moreover, countries around the world have hardly considered using solar panels to power an aircraft.

After all, in the research and investigation of everyone at that time, solar power generation was simply an impossible road to realize.

Therefore, there were no experts who studied the photoelectric effect squatting in the live broadcast room at all.

But soon, someone will be able to answer this question.

Looking at the barrage of constant quarrels, Han Yuan smiled and explained:
"The photoelectric conversion efficiency of 70.00% is already very high."

"Gallium lanthanide silicon thin films are almost the limit of what can be done in silicon-based solar panels without changing the silicon substrate."

"The physical properties of silicon determine that no matter how it changes the doped lattice inside, the photoelectric conversion efficiency of its monolithic lattice will not be too high."

"As you said, the photoelectric conversion efficiency of 70.00% is not enough to power the aircraft."

"but."

Han Yuan paused, seduced the curiosity of the audience in the live broadcast room, and then continued:
"The photoelectric conversion rate of 70.00% is the conversion rate of a single silicon crystal."

"I can make the number of gallium lanthanide silicon films on a fixed area far exceed the surface area through various methods such as half-chip, stacking, and tiles, so as to achieve higher-efficiency photoelectric conversion."

"Simply put, like glass, lanthanum gallium silicon thin films can be stacked layer by layer."

"When the sun shines on it, it can penetrate multiple structures such as the first layer, the second layer, and the third layer, and finally realize the simultaneous power generation of multiple superimposed films."

"Although the lower the photoelectric conversion efficiency is, the lower the photoelectric conversion efficiency will be. However, multiple LaGaSi thin films can be tiled at the same time, and it is possible to supply power to the aircraft."

After listening to Han Yuan's explanation, most of the audience in the live broadcast room suddenly realized what was going on.

[It turned out to be like this. 】

【understood! 】

[One piece is 70.00%, if ten pieces are superimposed, wouldn't the photoelectric conversion rate be [-]%? 】

[Fuck, isn't this too exaggerated? 】

[What are you thinking, didn't you see that the anchor said that the lower the photoelectric replacement rate is, the lower it is?Can light penetrate so many layers of film? 】

【That's scary too. If I superimpose two layers, the photoelectric conversion rate will exceed one. Is this realistic? 】

[One piece of light generates two degrees of electricity, isn't this energy unconserved? 】

[Why does it sound so nonsense? 】

[If it is announced by other people or other countries, even if it is a Nobel laureate, I am sure that some laboratory has insufficient funds to cheat the funds, but this anchor, let’s take a look first. 】

[This is obviously something that violates the laws of physics, right?How is it possible? 】

[? ? ?Why is it against the laws of physics? The conversion rate of a monolithic film is only 70.00%. Why is energy not conserved? 】

[Why is it conserved?The conversion rate of the first film is 70.00%, that is, it absorbs 70.00% of the light energy. Even if it is transmitted to the second film, the remaining 30.00% of the light energy cannot reach such a high efficiency, right? 】

[Unfortunately, I thought this anchor was a real alien or a technical anchor, but I didn’t expect that he was actually a liar. The previous electric propulsion system was also a fake. 】

[So, this anchor fooled the whole world?is it possible?Are experts from all countries stupid?There are many experts in this live broadcast room, all of them are as stupid as you? 】

In the live broadcast room, the quarrel that had been suspended started to quarrel again.

The audience was divided into two factions, each holding their own views and arguing constantly.

One group thinks that this is something that violates the laws of physics, and it is impossible to do it, so they think that the Korean won is fake.

After all, no matter how high the photoelectric conversion rate is, there will always be losses after the first layer. No matter how much you stack, it is impossible to break through 100%.

The other school believes that this is normal, the conversion rate of a single silicon wafer is only 70.00%, and it can break through 100% after overlapping.

Plus this anchor has never deceived anyone about technology since the broadcast started, so stick to Won's side.

The two were arguing in the live broadcast room over whether the photoelectric conversion rate could break through 100%.
