The main material of solar panels is monocrystalline silicon or polycrystalline silicon wafers. The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 18%, and the highest reaches 24%. This is the highest photoelectric conversion efficiency of all kinds of solar cel......
