Answer:  The conversion efficiency is different.At present, the photoelectric conversion efficiency of monocrystalline silicon solar cells is about 17%, and the highest is 24%, which is the highest photoelectric conversion efficiency of all types of solar cells at present. The production process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystallinesilicon solar cells has to be reduced a lot, and its photoelectric conversion efficiency is about 15%.
