    "Currently, the conversion rate of this kind of lens-type solar cells has reached a certain limit. Without the emergence of more advanced materials, according to Edwards and I's predictions, this kind of lens-type solar cells will not be able to operate according to the current situation.  , it would be good if we could achieve a photoelectric conversion rate of 30%. ([] ) This is still under the model where we use a thousand times or even fifteen hundred times lens. If this is the case, it will be difficult to produce this  The cost of a solar cell will increase, and according to our calculations, if we use a thousand times this kind of concentrating solar cell, we will have an array of sixteen concentrating solar cells on a lighting area of ??three square meters. In conversion  Under ideal conditions, the same light intensity can achieve a power output of 800 watts without much improvement in efficiency. Compared with the current flat-panel solar cells, which are best at 150 watts per square meter, the data seems to have been greatly improved.  , but the effect in terms of field output improvement is actually not ideal. Moreover, due to the use of large cooling equipment, the manufacturing cost will be higher, and such solar cells cannot be supported and used in ordinary households."

    Matt explained to Jin Xiaoqiang, and Jin Xiaoqiang heard that it was indeed the case. The data of such a concentrating solar cell does seem to be several times higher than the data of current ordinary solar cells.

    ¡°But if you take into account its manufacturing cost and power transmission issues, such a solar cell does not have much practical significance for ordinary households.

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

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

    Early in the development of this solar energy project, Jin Xiaoqiang had done relevant research. There is a large amount of desert land in the west of our country, which is restricted by natural geography.  Most of them are idle and undeveloped.

    But whether it is suitable to carry out solar power generation projects on these lands. After research, the result is negative.

    The geographical environment of our country¡¯s western desert is completely different from the deserts in Nevada, Texas and Colorado in the United States because of the latitude.  These desert areas are geographically high.

    Although the light intensity is very high throughout the year and the lighting conditions are good, it is also affected by the cold air in Siberia. Half of the year is in the cold winter.

    Such cold seasons have a great impact on solar power generation, because a large amount of cold air will pass through, although it will help the heat dissipation of solar panels.  But it is also not conducive to the maintenance and upkeep of these solar panels.

    ¡°And the wind and sand are too heavy, which is not conducive to the work of these solar cells, and will cause serious corrosion to the solar panels. If a solar power plant is built in such a place, the cost of subsequent maintenance and upkeep will be high.

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

    In fact, there are many places in our country that are most suitable for building such solar power plants. The most suitable place is actually the Qinghai-Tibet Plateau.  It has plenty of sunshine and is inaccessible. What¡¯s more, the natural environment is not as harsh as those in desertified lands.

    Although it is subject to some wind and snow every year, the consequences are not as severe as in the western desert areas, and it is very suitable for manufacturing large-scale solar power plants.

    But one problem that troubles 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 the same goes for later maintenance and upkeep.  There are big problems.

    Which is the most suitable place in the country to build such a solar power plant.  I'm afraid it is Nanhai Province. Because it is located in a tropical area and there are no heavy industries in the entire province, the air pollution is not that serious. The sunshine hours throughout the year are long, and the temperature and environment are very suitable for building solar power plants.

    But the problem is that it is surrounded by ocean.  Therefore, the air humidity is high, and the moisture contains a lot of salt and other chemicals, which will cause more serious corrosion of solar panels. Later maintenance and upkeep is also a big problem.

    Now Matt also said that although this kind of solar panel looks beautiful in terms of data, there are still some problems in terms of photoelectric conversion efficiency, and the cost must also be considered in terms of long-distance transmission. In this way,  Now if we want to start building such aIn the case of solar power plants, the gains outweigh the losses.

    ¡°So in the absence of the emergence of new materials, we plan to use a new model of solar cells. In this solar cell, we will use new metal particle injection technology, so that new models of solar cells can be integrated.  The cell is divided into three layers. The first layer is a monocrystalline silicon cell layer with our turbocharged solar technology, and then below we will inject two layers of metal particles, thus forming a three-layer solar cell. The first layer  The single crystal silicon will capture the red photons in the light and convert them into yellow photons. The metal particles in the second and third layers will capture the visible solar rays and ultraviolet rays in the light, thus forming a photon.  A solar panel that captures the triple functions of visible sunlight, infrared rays, and ultraviolet rays. The thickness of the entire solar panel is about two hundred millimeters, with a total of three solar conversion layers, so that it can be used without getting more advanced  In the case of materials, solar energy can be converted into electrical energy more efficiently."

    As Matt explained, the structural diagram and design pattern of this new solar cell continued to appear on the projection screen behind him.

    Jin Xiaoqiang was very moved after seeing it. Indeed, such a solar cell is indeed the most reasonable design when he does not plan to come up with new solar energy conversion materials.

    ¡°We plan to name this new type of solar cell a lens-type multi-section solar cell.¡±

    When Jin Xiaoqiang heard this, he nodded frequently to express his satisfaction.

    "What is his highest photoelectric conversion efficiency?"

    "Theoretically, it can reach up to 40%"

    Matt said to Jin Xiaoqiang with a proud face, but he didn't know that Jin Xiaoqiang felt very confused when he heard this data.

    If such a battery is developed, it will definitely not be used in solar power generation projects. If it is, it will definitely have a considerable impact on the oil world, and it will definitely cause a lot of trouble to ourselves. If not  Go on, then such a treasure will rot in your own hands?

    Jin Xiaoqiang felt very unhappy.

    "We have made calculations. If such a new solar cell is focused a thousand times in a three-square-meter array solar panel mode, the power output can reach 4.2 kilowatts. A one-square-kilometer solar power plant can provide 1,050,000 watts.  Thousands of kilowatts/hour of electric power supply. If we follow your country's current economic development rate, we build 100,000 square kilometers of solar power plants, and if they are all used for solar energy, we can supply the country's electricity needs! If we build more than 100,000 square kilometers  Solar power plants can ensure China¡¯s economic development needs in the next twenty years.¡±

    Matt's eyes were already glowing red when he said this. Obviously, they regard China as a huge testing ground. If his and Edwards' experiments are successful, then the two of them will be the energy revolution of mankind in the future.  As a pioneer, it will be written down in the history textbooks of various countries in the world in the future. It will be a piece of cake to win the Nobel Prize.

    If this experiment is successful, then their two names may be as famous as scientific giants such as Einstein and Newton in the future.

    Looking at the blushing Matt and Edwards, whose faces were also turned red by Matt's words, how could Jin Xiaoqiang, a shopping mall veteran, not know what these two people were thinking?

    It seems that these scientists are also ordinary people, and they also value fame and fortune. The two in front of them may not be so sensitive to money, but they definitely value reputation very much.

    They didn't know that the monocrystalline silicon material with the custom structure they hoped for could actually be obtained by themselves in minutes. If that new material was taken out, it would match the battery they are currently researching.  Well, wouldn¡¯t the photoelectric conversion efficiency of this new type of solar cell reach 50% or even higher?

    ¡°If that¡¯s the case, before those foreign oil tycoons take action, 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 trouble for Jin Xiaoqiang.

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

    "Boss, we have also done a survey. In the northwest region of China, especially the Qinghai-Tibet Plateau, there are places with scarce rainfall and long sunshine hours. There are almost 3,000 hours of sunshine every year. Such high-intensity sunlight collection areas,  But it is very suitable for building such a solar power plant"

    Jin Xiaoqiang feels like his head is getting bigger.??These two emotions have even calculated the geographical environment of the Celestial Dynasty.  .  .
