Laminated structure of photovoltaic assembly, preparation method therefor, and photovoltaic assembly

摘要

A laminated structure of a photovoltaic assembly. The laminated structure comprises a first packaging layer (11a), a solar cell array (13a), and a second packaging layer (14a). The first packaging layer (11a) is prepared by using 30 to 50 parts of fiber cloth and 50 to 70 parts of first packaging powder coating in parts by weight, and the first packaging powder coating is evenly coated on the fiber cloth. The second packaging layer (14a) is prepared by using 30 to 50 parts of fiber cloth and 50 to 70 parts of second packaging powder coating in parts by weight, and the second packaging powder coating is evenly coated on the fiber cloth. The first packaging powder coating is an acrylic acid powder coating or a super-weather-resistant polyacrylic acid powder coating, and the second packaging powder coating is a super-weather-resistant polyester powder coating. The laminated structure has low costs, and the light weight of the packaging materials of the photovoltaic assembly is achieved on the premise that ultraviolet resistance, aging resistance, impact resistance, fire resistance and other technical requirements in the photovoltaic industry.
