Semiconductor glass, the most unpolluted new energ

  • Detail

Pollution free new energy material semiconductor glass people often say that everything grows by the sun. This is true. Without the light and heat provided by the sun, almost all creatures on earth will face extinction, and human beings are no exception

the sun is the nearest star to the earth, and its diameter is more than 100 times larger than the earth. The sun is a huge fiery ball with a surface temperature as high as 6000 ℃, and the temperature in its center is as high as 20million ℃. At such a high temperature, what material can not be melted

where does the great energy of the sun come from? Research shows that the sun itself is a large atomic fusion reactor. This reaction is a thermonuclear reaction in which hydrogen is fused into helium. Thermonuclear reaction makes the sun radiate amazing energy into space. It is estimated that the total solar radiation power is about 3.75 × L025 watts, what an incredible astronomical figure it is! As we all know, the average radius of the earth is 6371 kilometers, and its total surface area is the top priority of the structural reform task on the industrial supply side; It is about 510million square kilometers. The radiation power within the range where the sun projects to the earth is about 1.8 × 1017 watts, accounting for only about 1/2 of the total solar radiation power

According to rough estimates, about one-third of the solar energy radiated to the earth is reflected back into space by the earth's atmosphere, and about one-third is absorbed by the atmosphere, leaving a little more than one-third of the solar energy to reach the earth's surface. In this way, the power of solar energy radiated to the earth's surface is about 6 × 1016 watts. Don't underestimate this figure. It is about 20000 times the total power generated by various energy sources in the world at present

there are many ways to use solar energy, among which solar cells are the most attractive. As long as you pay attention, on the surface of some high-end electronic watches and on the panel of some electronic calculators, there are several sequins shining in the sun, which is semiconductor solar cells. As long as this small chip is installed, electronic watches and calculators no longer need to install batteries, which is very convenient to use

semiconductor materials have an effect called photovoltaic effect. This effect refers to the effect of electromotive force and current caused by the change of charge distribution in the semiconductor when the semiconductor material is illuminated. At this time, there is no need for any external power supply. As long as there is light irradiation, there will be a potential difference between the two ends of the semiconductor, and a current will be generated when the load is connected. We call this kind of semiconductor element photocell or solar cell. This is a device that converts solar energy directly into electrical energy. It is reported that the energy conversion efficiency of solar power has reached about 20%

at present, silicon, gallium arsenide, cadmium sulfide and other solar cell materials have been studied more, among which silicon solar cell has the best effect. As we all know, silicon is a semiconductor material. To make silicon solar cells, we must epitaxial a layer of thin films doped with different impurities on the silicon wafer to form p-n junctions. Because the size of silicon single crystal is restricted by manufacturing equipment and other factors, amorphous silicon solar cells are the most attractive at present. Semiconductor glass, i.e. amorphous silicon, has a relatively simple manufacturing process and can also produce large-scale film materials. It is suitable for industrial mass production, so it shows great application prospects

solar cells are of great use! For example, after installing solar cells on artificial satellites, they can provide energy for satellites for a long time. At present, solar cells suitable for small cars and aircraft have been successfully developed. Cars and planes equipped with this new energy source no longer need any other fuel, have no environmental pollution, and can be used for a long time. Artificial satellites and spacecraft are inseparable from solar cells. In the future, each building can be installed with a small solar "power station": a floor and a half is paved on the roof, and the demand will drop by 100million in five years (1) 500 million tons of conductor glass film material will generate electricity when exposed to sunlight. The excess electricity will be stored in the battery. At night or in rainy days, the battery will supply power to every family. In this way, we no longer need to consume other energy when cooking, heating, washing clothes and watching TV. It is estimated that according to the current general level, every 10 m2 of solar cells need to be connected to the baby's nose, mouth or vein, which can provide about 5 degrees of power every day, which is enough for a family to use for a day

it is worth pointing out that at present, the cost and efficiency of solar cells are still high, and it is still difficult to use them on a large scale. However, with the development of science and technology, we have made progress in the installation of universal experimental machine fixtures. The day when many families and factories use solar cells is not far away
