There are several reasons why polysilicon is generally used
2021-11-15
1. The difference in appearance
From the appearance, the four corners of the monocrystalline silicon solar panel are arc-shaped, and there are no markings on the surface; while the four corners of the polycrystalline silicon solar panel are square corners, and the surface has the same markings as ice flowers.
2. Use the difference above
For users, there is not much difference between monocrystalline silicon solar panels and polycrystalline silicon solar panels, and their life and stability are very good. Although the uniform conversion power of monocrystalline silicon solar energy is about 1% higher than that of polycrystalline silicon, because monocrystalline silicon cells can only be made into a quasi-square shape (all four sides are arc-shaped), there will be a part of the area when forming solar panels. It is not full; polysilicon is square, so there is no such a problem.
3. Production process
From the appearance, the four corners of the monocrystalline silicon solar panel are arc-shaped, and there are no markings on the surface; while the four corners of the polycrystalline silicon solar panel are square corners, and the surface has the same markings as ice flowers.

It is not full; polysilicon is square, so there is no such a problem.
3. Production process
The energy consumed in the production of polycrystalline silicon solar cells is about 30% less than that of monocrystalline silicon solar cells. Therefore, polycrystalline silicon solar cells account for a large proportion of the total global solar cell production, and the production cost is also less than that of monocrystalline silicon cells. Therefore, the use of polycrystalline silicon solar cells will It will be more energy-saving and environmentally friendly!
