"At present, this kind of lens-type solar cell has reached a certain limit in terms of conversion rate, and if there are no more advanced materials, according to my prediction and Edwards, this kind of lens-type solar cell can reach 30% photoelectric conversion rate according to the current situation, it is already good. This is still under the model of using a 1,000x or even 1,500x lens. If this happens, the cost of producing such solar cells will increase, and according to our calculations, if we use a thousand times more concentrated solar cells, we will now have 16 concentrated solar cells arrayed on a three-square-meter daylight area. In the case that the conversion rate is not much improved, the same light intensity is under ideal conditions. It can reach a power output of 800 watts.

Compared with the current flat panel solar cells, which is optimally 150 watts per square meter, it seems to be a great improvement in the data, but the effect is not ideal in terms of field output improvement. And because of the use of large cooling equipment, the manufacturing cost will be higher, so such solar cells cannot support and be used in ordinary homes. ”

Matt explained to Jin Xiaoqiang, Jin Xiaoqiang heard that it was indeed the same, such a concentrated solar cell, it seems that the data is indeed several times higher than the current ordinary solar cell data.

But if you take into account his manufacturing costs and power transmission problems, such solar cells really don't have much practical significance for ordinary families.

The best use of such solar cells is to build a huge solar daylight power plant, but if such a power plant is built, the cost will not be less than billions, or even tens of billions.

And now it is difficult to say whether it is cost-effective to invest in such a project.

As early as when he was engaged in this solar project, Jin Xiaoqiang had done research on related aspects, and there was a large amount of desert land in the western part of China, most of which were in an undeveloped state due to the limitations of natural geography.

But whether these lands are suitable for solar power generation projects, after research, this result is negative.

The geographical environment of China's western desert is completely different from the nature of the deserts in Nevada, Texas and Colorado in the United States.

Although the light intensity is high throughout the year, the lighting conditions are good, but it is also affected by the cold Siberian air, and there is a cold winter for half of the year.

Such a cold season has a great impact on solar power generation, because there will be a large amount of cold air passing through, although it will help the heat dissipation of solar panels, but it is also not conducive to the maintenance and maintenance of these solar panels.

In addition, the wind and sand are too large, which is not conducive to the operation of these solar cells, and will cause serious corrosion to the solar panels, and if a solar power plant is built in such a place, the cost of maintenance and maintenance will be high.

And because of the natural environment, the photoelectric conversion efficiency of such solar panels in the laboratory may reach 30%, but if they are in such a harsh natural environment, their photoelectric conversion efficiency is difficult to guarantee.

In fact, the most suitable place to build such a solar power plant in China is not nothing, the most suitable place is actually the Qinghai-Tibet Plateau, where the sunshine is abundant, and it is inaccessible, and there is another point that the natural environment is not so harsh compared to those desertified lands.

Although there are some winds and snowstorms every year, the consequences are not as severe as in the western desert areas, which are suitable for large-scale solar power plants. …,

But one of the problems that plagued Jin Xiaoqiang is the altitude of the Qinghai-Tibet Plateau, where is the roof of the world, because the altitude is high, it will have a great impact on the construction cost of solar power plants, and there are also big problems in the later maintenance and maintenance.

Because it is located in the tropics, and there is no heavy industry in the whole province, the air pollution is not so serious, and the sunshine hours are very long throughout the year, and the temperature and environment are very suitable for the construction of solar power plants.

But the problem is that because the surrounding ocean is around, the air humidity is high, and the moisture carries more salts and other chemicals, which is more serious for the corrosion of solar panels, and the later maintenance and maintenance are also a big problem.

Now Matt also said that although this kind of solar panel looks beautiful in terms of data, in fact, there will still be some problems in terms of photoelectric conversion efficiency, and the cost should also be considered in long-distance transmission, so that if you want to start building such a solar power plant now, then it will be a little more than worth the loss.

"So in the absence of new materials, we plan to adopt a new model of solar cells, in which we will use a new metal particle injection technology, so that the new model of solar cells can be divided into three layers. The first layer is a monocrystalline silicon cell layer with our turbocharged solar technology, and then below we inject two layers of metal particles to form a three-layer solar cell. The first layer of monocrystalline silicon captures the red photons in the light and converts them into yellow photons, and the metal particles in the second and third layers capture the visible sunlight and ultraviolet rays in the light, so that solar panels can form a triple function of catching visible sunlight, infrared rays, and ultraviolet rays. The thickness of the entire solar panel is about 200 millimeters, and there are three layers of solar conversion layer, so that the solar energy can be converted into electricity more effectively without obtaining more advanced materials.

As Matt explains, schematic diagrams of the structure of this new type of solar cell and design patterns continue to appear on the projection screen behind him.

Jin Xiaoqiang was very moved after seeing it, it is true that such a solar cell, in the case that he does not plan to come up with new solar conversion materials, is indeed only the most reasonable design.

"This new type of solar cell, we plan to name it lenticular multi-cell solar cell."

Jin Xiaoqiang nodded frequently when he heard this, expressing satisfaction.

"What is the highest photoelectric conversion efficiency of his?"

"Theoretically, it can be up to 40 percent......"

Matt said to Jin Xiaoqiang with pride on his face, but he didn't know that Jin Xiaoqiang felt very entangled as soon as he heard this data.

If such a battery comes out, you can't get on the solar power project, if it does, then it will definitely have a considerable impact on the oil world, and it will definitely bring a lot of trouble to yourself, if not, then such a baby will rot in your own hands

Jin Xiaoqiang felt very unhappy.

"We have calculated that if such a new solar cell is 1,000 times focused on the three-square-meter array solar panel mode, then the power output can reach 4.2 kilowatts. A solar power plant per square kilometer can provide a supply of 1 million and 5 kilowatts per hour. If we build 100,000 square kilometers of solar power plants according to the current economic development rate of your Celestial Empire, and all of them are opened up for solar energy, we can supply the electricity demand of the whole country! If an additional 100,000 square kilometers of solar power plants are built, then it will be able to meet the needs of the economic development of the Celestial Empire in the next two decades. ”…,

When he said this, this Matt's eyes were already red, obviously they used the Celestial Empire as a huge testing ground, if he and Edwards' experiment was successful, then the two of them would be the pioneers of the future human energy revolution, and it would be appropriate to write it in the history textbooks of all countries in the world in the future, what a Nobel Prize, it would be a piece of cake.

If this experiment is successful, then the names of the two of them may be on par with those of Einstein and Newton in the future.

Looking at Matt, who was full of red light, and Edwards, who was also blushed by Matt's words, Jin Xiaoqiang, an old fritter in the shopping mall, how could he not know what these two people were thinking?

It seems that this scientist is also an ordinary man, and he attaches great importance to fame and fortune, and the two in front of him may not be so sensitive to money, but for fame, these two people must be very important.

They don't know that the monocrystalline silicon material with the habit structure they hope for can actually be obtained in every minute, and if the new material is taken out and matched with the battery that the two of them are currently researching, then the photoelectric conversion efficiency of this new type of solar cell can reach 50% or even higher?

If that's the case, it is estimated that without waiting for the foreign oil tycoons to do it, it is estimated that the domestic oil and petrochemical industry will have to take the lead in doing it themselves.

So this new type of solar cell is really a happy worry for Jin Xiaoqiang.

Do you support the two of them to continue to work on this new type of battery? At this time, Jin Xiaoqiang was a little embarrassed.

"Boss, we have also done a survey, in the great northwest region of the Celestial Empire, especially in the Qinghai-Tibet Plateau, some places have scarce rainfall and long sunshine hours, almost 3,000 hours of sunshine per year, such a high-intensity solar ray collection place is very suitable for the construction of such a solar power plant......

Jin Xiaoqiang felt that his head was too big, and these two feelings had even been calculated in terms of the geographical environment of the Celestial Empire...... ）
