Abstract
The invention discloses a cover plate which is used in a crystalline silicon photovoltaic module. A plurality of hemispherical protrusions are arranged on the upper surface of the cover plate, and the protrusions are evenly and sequentially distributed on the upper surface of the cover plate along the length direction and the width direction. During working, the protrusions can effectively absorb sunlight incident from different angles, so that the sunlight form diffuse reflection on the upper surface of the cover plate, accordingly illumination loss caused by reflection is remarkably reduced, illumination use ratio of the sunlight is effectively improved, and the illumination use ratio of the crystalline silicon photovoltaic module under illumination incidence conditions of different angles is correspondingly improved. The invention further discloses the crystalline silicon photovoltaic module using the cover plate, the illumination use ratio of the crystalline silicon photovoltaic module is high, and the illumination loss is low.
