The sun is a natural source of energy. Every living organism on earth has the ability to play its role, and even its existence is directly or indirectly from the energy of the sun. Our earth is about one hundred million miles from the sun. The radiant energy it cuts off is less than incredible (about three parts per million). Such a small energy is actually one hundred thousand times larger than that of the whole world at present. At present, the world, especially the industrial developed countries, began to feel a shortage of energy, so people began to turn to solar energy in order to solve the energy crisis.
Solar energy can be supplied infinitely every day, and the quantity is huge. If used in large power plants, the greenhouse effect will be reduced. Some energy experts and environmental protection experts believe that the thermal influence of solar energy will be much smaller than that of any other alternatives to meet the future energy needs of mankind. As a kind of new energy that does not pollute the environment, it is inexhaustible, it is everywhere. Especially in terms of power supply, solar energy utilization has two ways: passive utilization (photo thermal conversion, such as solar water heater) and photoelectric conversion (such as photovoltaic power generation). Some experts believe that solar power will eventually account for 20% of the power supply.
Solar energy is a kind of radiant energy. Solar power means that to convert sunlight directly into electrical energy, it must be transformed into electric energy by means of energy converter. The process of direct conversion of light energy into electrical energy is exactly called the photovoltaic effect. Without the need for any other mechanical component, the energy in the light is obtained by the electrons of the semiconductor device, and the energy is generated. This energy converter, which converts light energy into electrical energy, is a solar cell. Solar cells, like transistors, are made up of semiconductors. Its main material is silicon, and there are some other alloys. High purity silicon used in the manufacture of solar cells is made by special purification. Solar cells can convert light energy into electric energy only if they are irradiated by sunlight or light, so that electric current can flow from one side to the other side, and usually generate electricity equivalent to 10~20% received by light.
In general, the stronger the light, the more electricity is generated. In order to make solar panels to minimize light reflection, converting solar energy into electric energy, are generally in the above its upper layer can prevent the light reflection film, the surface of the solar panel is purple. The principle of its work is based on the photovoltaic effect of the semiconductor pn junction. The so-called photovoltaic effect is a kind of effect of electromotive force and current when the object is exposed to light, and the distribution of charge in the object is changed. When the sun or other light illuminates the PN junction of the semiconductor, the voltage (called the photogenerated voltage) appears on both sides of the PN junction. This phenomenon is the famous light volt effect. If the PN junction is short circuited, the current will be generated.
The main advantage of solar power is that solar cells can be installed on rooftops and other spaces which are usually not used, without noise and long life. And once set up, there is almost no need for adjustment. Now, as long as the roof is filled with solar cells, the self - supply of electricity in the home can be realized. The main use of solar energy is no longer small, in nature, it is professional. It has played an important role in the field of military, communication and urban construction. Venezuela has also launched cheap solar cars, and European scientists have developed portable solar cells that can be worn on the body. At present, the utilization of solar energy has a huge space for development, and the related technology may achieve a breakthrough in a short time. It has been used as an important part of its energy strategy by many developed countries.
