Of course, solar panels are best made from polycrystalline silicon! Polycrystalline silicon solar panels are typically two to three times faster than monocrystalline silicon. To stabilize voltage, solar panels work by generating an electric current through the directional movement of electrons. Typically, monocrystalline silicon panels are much thinner than polycrystalline silicon panels and are also very inexpensive.
The difference between monocrystalline silicon and polycrystalline silicon is that monocrystalline silicon looks like a blackboard. There will be no reflection lines. However, the polysilicon appears to have ice cracks.
Depending on the different materials used, solar cells can be divided into:
1. Silicon solar cells
2. Inorganic salts such as gallium III arsenide; - Batteries made upV compounds, cadmium sulfide, copper, indium and other multicomponent compounds
3. Large solar cells made of functional polymer materials
4. wait.
No matter what material is used to make the battery, the general requirements for solar cell materials are:
1. The band gap of the semiconductor material cannot be too big ; It should have high photoelectric conversion efficiency: 3. The material itself does not cause pollution to the environment; 4. The material is easy to produce industrially and has stable material performance. Based on the above considerations, silicon is the most ideal solar cell material, which is also the main reason why solar cells are mainly silicon-based materials. However, with the continued development of new materials and technologies, solar cells based on other materials display increasingly attractive prospects.
