Abstract

The invention discloses a high-efficiency solar packaging film. The film comprises an upper layer film and a lower layer film, wherein the upper layer film comprises, by mass, 100 parts of ethylene-vinyl acetate (EVA) resin, 0.1-10 parts of peroxide, 0.1-5 parts of assistant crosslinkers, 0.1-5 parts of silane coupling agents and 0.1-15 parts of stable assistants; the lower layer film comprises, by mass, 100 parts of ethylene-vinyl acetate (EVA) resin, 0.1-10 parts of peroxide, 0.1-5 parts of assistant crosslinkers and 0.1-15 parts of stable assistants; and the lower layer film also comprises, by mass, one type or more types of titanium pigment, zinc oxide, calcium carbonate, barium sulfate, ferric oxide and carbon black. The film has good sunlight reflection capability and can prevent ultraviolet rays of sunlight effectively. The photoelectric conversion efficiency of solar assemblies is improved, the cost of solar assemblies is reduced and the service life of solar assemblies is prolonged.

Description

technical field

[0001] The invention relates to a solar energy encapsulation adhesive film, in particular to a solar energy encapsulation adhesive film composed of an upper layer adhesive film and a lower layer adhesive film with high photoelectric conversion efficiency. Background technique

[0002] Solar energy is an excellent choice to replace the increasingly depleted petroleum energy. In recent years, crystalline silicon solar cells have received great attention and development. The main body of a typical crystalline silicon solar cell module is a laminate of multi-layer materials. The structure of the laminate is a layer of glass, a layer of encapsulation film, and a layer of solar cells from top to bottom. , a layer of packaging film and a layer of backplane. In the current commercial crystalline silicon solar modules, the encapsulation film is mainly made of ethylene-vinyl acetate copolymer (hereinafter referred to as EVA), and the upper and lower layers of encapsu...
