Monocrystalline and polycrystalline silicon are raw materials used to make solar panels.
Polysilicon photovoltaic modules are cost-effective, and the power generation efficiency of polysilicon photovoltaic modules in Jiaoda Optics Valley is usually around 17%. The speed of polycrystalline silicon solar panels is generally two to three times that of monocrystalline silicon, and the voltage should be more stable. Monocrystalline silicon photovoltaic modules have a higher photoelectric conversion rate and perform better than similar products in low-light conditions. Polycrystalline silicon photovoltaic modules are composed of polycrystalline solar cells arranged in different strings and parallel arrays.
The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, and its photoelectric conversion efficiency is about 12%, which is slightly lower than that of monocrystalline silicon solar cells. Lots of development.
There is no upstream and downstream relationship between the uses of monocrystalline silicon and polycrystalline silicon, and the production process cannot be connected with each other. They are all used to make solar cells, and the crystal structure is different. A solar cell of monocrystalline silicon has the same crystal structure, while polycrystalline silicon is the opposite, so it looks different. Generally, the conversion rate of monocrystalline silicon is high.
