Abstract

The invention discloses a double-glass assembly of a high-efficiency and high-strength solar cell. The double-glass assembly has a five-layer structure comprising photovoltaic glass, a front encapsulated coating, a solar cell string, a back encapsulated coating and float glass in sequence from top to bottom, wherein the five-layer structure is formed by cross-linking and curing the front encapsulated coating and the back encapsulated coating after vacuumizing, heating and lamination to firmly bond the five layers of the structure together, and installing an aluminum alloy frame and a junction box via a silica gel sealing assembly. The encapsulated coating is made of ethylene-vinyl acetate copolymer, polyolefin elastomer, polyvinyl butyral or liquid silica gel or the like. The float glass can be transparent or white according to actual purposes of the assembly, sealing with the aluminum alloy frame can effectively improve the mechanical properties of the double-glass assembly and is compatible with the traditional installation mode, the double-glass assembly is convenient to install, and auxiliary design can be increased in the assembly applied in a severe environment to greatly improve the snow load performance of the assembly.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic modules, and in particular relates to a double-glass solar battery module with high efficiency and high strength. Background technique [0002] Traditional solar photovoltaic modules generally have a five-layer structure. From top to bottom, they are photovoltaic glass, encapsulation film, battery sheet, encapsulation film and backplane. The adhesive film is cross-linked and cured, and the five-layer structure is firmly bonded together. After adding an aluminum frame and a junction box and using silicone to seal the components, a conventional solar photovoltaic module is produced. Ultra-clear embossed tempered glass is generally used for glass, and ethylene-vinyl acetate copolymer (EVA) is generally used for packaging materials. Traditional photovoltaic modules have large mechanical load deformation. When the load fails, it will also be cracked due to the snow load when it is used on the system ...
