1. Properties
Crystalline silicon solar cell module: The most widely used solar cell, mainly due to the stability of crystalline silicon and its efficiency which can reach 15% to 25%.
Thin-film solar modules: Using discarded silicon wafers, silicon wafers are not necessarily cheap given their efficiency levels.
2. Features
Crystalline silicon solar cell modules: Monocrystalline silicon comes from high purity single crystals, cut into wafers with a diameter of 150mm and a thickness of 200mm. Polycrystalline silicon is more popular and can be manufactured in larger quantities. For example, silicon is cut into strips and then sliced. The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, butphotoelectric conversion efficiency. of polycrystalline silicon solar cells is much lower, its photoelectric conversion efficiency is about 15%.
Thin film solar modules: The manufacturing method is completely different from crystalline silicon solar cells. The process is greatly simplified. The silicon consumption is very low and the power consumption is lower. it can produce 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. Over time, its conversion efficiency decreases.
