Okay, polysilicon. 1. Monocrystalline Silicon Polycrystalline silicon is a raw material used to make solar panels. 2. Silicon is an extremely abundant element on earth. It is present almost everywhere and can be considered inexhaustible. There is no shortage of raw materials for manufacturing silicon-based solar cells. 3. The speed of polycrystalline silicon solar panels is generally two to three times that of monocrystalline silicon, and the voltage should be stable. 4. The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, and the photoelectric conversion efficiency is about 12%, which is slightly lower than that of monocrystalline silicon solar cells. . However, the manufacturing of the material is simple and convenient, consumes less energy, and the total production cost is low,it has therefore been considerably developed.
Single crystal has a high conversion efficiency and is expensive; polycrystalline has low conversion efficiency and is cheap.
There are many polycrystals in the domestic market, or they are all polycrystals.
The Japanese market is very popular recently, but Japan's requirements are very high and they are all monocrystalline. People's idea of Japan is to do your best and do it right the first time. It has very high requirements for mitigation effectiveness, and we need to learn from that at home.
