Photovoltaic glass surface. The coating liquid of photovoltaic module glass is coated on the surface of photovoltaic glass. Photovoltaic glass is one of the solar cell modules. Solar modules are mainly monocrystalline silicon or polycrystalline silicon cells, through which light energy is converted into electrical energy. Photovoltaic glass is used to encapsulate silicon wafers. The purpose is to improve its light absorption and radio and television conversion efficiency. It is a special glass.
