With the continuous optimization of solar photovoltaic modules, the conversion efficiency of crystalline silicon cell plates is close to the limit value, and glass is used as an important component of the module and plays a role in transmitting light and protecting a power generation main body (cell plate), wherein the front plate glass is generally ultra-white toughened glass, the light transmittance of 550nm reaches more than 91%, the light transmittance of 550nm of rear plate glass reaches more than 88%, and in order to further increase the light receiving quantity and the power generation quantity of the cell plate, technical measures are required to be further adopted to increase the light transmittance of the glass and reduce the surface reflectivity of the glass.
