A transparent substrate for a solar cell cover panel is introduced, which can increase the amount of light entering the solar cell module during daytime and year-round illumination, and/or effectively prevent environmental problems caused by light reflection on the light incident side of the module; A method of making the transparent substrate and a solar module containing such a substrate is also described. A semi-spherical recessed portion is formed on almost the entire surface of the cover glass, wherein the ratio d/D of the depth d of the central position of each recessed portion and the opening radius D of the recessed portion is between 0.1 and 0.50, and there is no recessed portion. The ratio of the planar portion to the incident side of the light does not exceed 40%.
