Embodiment 1

[0024] (1) Add 7 parts by weight of silicon dioxide and 2 parts by weight of benzotriazole series to 100 parts by weight of EVA (ethylene-vinyl acetate copolymer) resin (product of Samsung General Chemical Co., Ltd., South Korea, model E032A). Ultraviolet absorber (manufactured by Ciba Fine Chemicals, model UV329), fully mixed and heated until the EVA resin is fully melted, heat-preserved and smelted for 2 minutes, and then extruded by a T-die extruder to obtain a 200μm-thick adhesive layer.

[0025] (2) Stir 100 parts of HLK102-3 vinyl ester resin (Changzhou Hualike New Material Co., Ltd.) with 2 parts of methyl ethyl ketone peroxide and 2 parts of cobalt octanoate. The carbon fiber fabric of Wuxi Anfei Fiber Material Technology Co., Ltd. (the carbon fiber is the warp yarn and weft yarn of the base fabric, and the aramid fiber is the hook and loop yarn) is dipped in the solution to obtain a reinforced layer with a thickness of 100um.

Abstract

The invention provides a solar cell backplane which comprises an enhancement layer, a matrix layer and a bonding layer which are successively stacked. The enhancement layer is a composite material which is formed by fabrics and a polymer. The invention also provides a solar cell module containing the backplane. The solar cell backplane provided by the invention has good strength.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a solar cell backboard and a solar cell component. Background technique [0002] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect. It is a new type of power supply with three advantages of permanence, cleanliness and flexibility, and its market prospect is broad. Solar photovoltaic power generation will occupy an important seat in the world's energy consumption in the near future, not only to replace some conventional energy sources, but also to become the main body of the world's energy supply. [0003] A solar cell module is usually a stacked structure: it mainly includes layers such as a back sheet, a sealant layer, a battery sheet, a sealant layer, and a light-transmitting layer, which are laminated in sequence. Among them, the main function of the solar battery back sheet is to improve the overall mech...
