Abstract

The invention provides a glass cover sheet of a solar cell panel. The glass cover sheet has a four-layer structure, and comprises a surface layer elastomer film, a first toughened glass, an interlayerelastomer film and a second toughened glass which are sequentially arranged from top to bottom, wherein the thickness of the surface layer elastomer film is 1.5-2.5mm, the thickness of the first toughened glass is 2.0-3.0mm, the thickness of the interlayer elastomer film is 0.7-2.0mm, and the thickness of the second toughened glass is 2.0-3.0mm. The surface layer elastomer film comprises the following components in percentage by mass: 65-85% of polyvinyl butyral, 10-40% of polyethylene resin, 0.1-1.0% of a wear-resistant agent, 0.2-5.0% of a nucleating agent and 0-5.0% of a compatilizer; theinterlayer elastomer film comprises the following components in percentage by mass: 75-85% of polyvinyl butyral, 5-20% of polyethylene resin, 0.2-3.0% of a nucleating agent and 0-5.0% of a compatilizer. The glass cover sheet has the four-layer structure, the surface layer elastic film mainly exerts the effects of light transmission and abrasion resistance, and the interlayer elastomer film can improve the toughness of the solar glass cover sheet, so that the solar glass cover sheet is not easily broken, and is better adapted to different weather conditions outdoors.

Description

technical field [0001] The invention relates to the field of solar cell devices, in particular to a glass cover sheet of a solar cell panel. Background technique [0002] In order to protect the solar panel, a glass cover sheet is usually glued on the solar panel. The glass cover of the solar panel is originally composed of a single glass. With the development of technology, the glass cover of the solar panel has developed from a single glass to an optical system composed of multi-layer materials. The main indicators for evaluating solar glass cover sheets are the strength, transparency and wear resistance of the glass cover sheets. In order to solve the problem of transparency, the usual method is to coat a layer of anti-reflection film on the glass cover, but the strength and weather resistance of the anti-reflection film are poor, and the solar energy will be damaged in bad weather, which will affect the power generation effect.
