Cover glass for a solar battery

A a transparent substrate for solar cell cover plate, which can enhance during day and an annual of the solar cell module in the light quantity, and/or effectively is prevented from the environmental distribution of the light module of incidence polishing reflective, soIs a a 0.1-1 the transparent substrate and comprising a substrate and method for solar assembly. The protection at polishing incidence's almost whole surface is formed with a hollow part; each hollow part is locations' depth d and ratio of d/D hollow part opening radius D of 0.1-0.50, there is no hollow part plane part is located at the light preventing side ratio not more than 40%.
