[0002] The solar energy irradiated on the earth is very huge. According to statistics, the solar energy irradiated on the earth for about 40 minutes is enough for the energy consumption of human beings all over the world for one year. It can be said that solar energy is truly inexhaustible and inexhaustible energy. Moreover, solar power generation is absolutely clean and does not produce pollution, so solar power generation is known as an ideal energy source. Solar energy is a clean and renewable new energy source, which is more and more popular among people. It has a wide range of applications in people's lives and work. Function; one of them is to convert solar energy into electrical energy. Solar cells use solar energy to work, and the working principle of solar thermal power stations is to use concentrated sunlight to boil water into water vapor, which is then used to generate electricity. Solar thermal power generation is to convert solar energy into thermal energy first, and then convert thermal energy into electrical energy. It has two conversion methods: one is to directly convert solar thermal energy into electrical energy, such as thermoelectric power generation of semiconductor or metal materials, and thermal energy in vacuum devices. Electronic and thermoelectric ion power generation, alkali metal thermoelectric conversion, and magnetic fluid power generation, etc.; another way is to use solar thermal energy to drive a generator to generate electricity through a heat engine (such as a steam turbine), which is similar to conventional thermal power generation, except that its heat energy does not come from fuel. , but from solar energy; the current technical conversion rate of solar energy into electrical energy is below 10%, the disadvantage of low conversion rate
