(1) Monocrystalline silicon solar cells The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 17%, and the highest is 24%, which is the highest photoelectric conversion efficiency of all kinds of solar cells, but the production cost is very large, so that it can not be widely and universally used. Because monocrystalline silicon is generally packaged with tempered glass and waterproof resin, it is robust and durable, and most manufacturers generally provide 25 years of quality assurance.
Single crystal flexible solar modules: flexible solar modules are also known as flexible components, the so-called flexible, means that the panel can be bent. Bending Angle up to 30 degrees. Solar modules (also known as solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system.
(2) polycrystalline silicon solar cells The production process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is reduced a lot, and the photoelectric conversion efficiency is about 15%. In terms of production cost, it is cheaper than monocrystalline silicon solar cells, the material is simple to manufacture, saves power consumption, and the total production cost is low, so it has been developed in large numbers. In addition, the service life of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of performance-price ratio, monocrystalline silicon solar cells are slightly better.
(3) Amorphous silicon solar cells Amorphous silicon solar cells are a new type of thin-film solar cells appeared in 1976, it is completely different from the production method of monocrystal silicon and polysilicon solar cells, the process is greatly simplified, silicon material consumption is little, lower power consumption, its main advantage is that it can also generate electricity in low light conditions. However, the main problem of amorphous silicon solar cells is that the photoelectric conversion efficiency is low, the international advanced level is about 10%, and it is not stable enough, and its conversion efficiency decreases with the extension of time.
