Abstract
The utility model discloses a cover plate which is used for a crystalline silicon photovoltaic module. A plurality of protrusions are arranged on an upper surface of the cover plate, the protrusions are hemispheric, and the protrusions are sequentially and evenly distributed on an upper surface of the cover plate along the length direction and the width direction. In a working process, the protrusions can effectively absorb sunlight coming in from different angles to conveniently form diffuse reflection on the upper surface of the cover plate, accordingly obviously reduce illumination loss caused by reflection, effectively improve illumination use ratio of the sunlight and enable the illumination use ratio of the crystalline silicon photovoltaic module under illumination incidence conditions at different angles to be correspondingly improved. The utility model further discloses the crystalline silicon photovoltaic module applied to the cover plate. The crystalline silicon photovoltaic module is high in the illumination use ratio and less in illumination loss.
