Embodiment Construction

[0026] like Figure 2-3 As shown, an amorphous silicon thin film photovoltaic module includes: tempered glass 11 located outside the front glass 13 and bonded to the front glass 13 through an adhesive layer 12 . It is used to protect the front plate glass 13, which enhances the strength of the front panel of the solar cell. Preferably, the thickness of the tempered glass 11 is 5-15 mm, and the mechanical strength of the entire solar cell module is improved through the tempered glass.

[0027] The adhesive layer 12 is located between the toughened glass 11 and the front glass 13 and is used for bonding the front glass 11 and the toughened glass 12 together. It adopts transparent bonding material and has good light transmittance. Preferably, the adhesive layer 12 is made of polyvinyl butyral PVB, EVA resin or other transparent adhesive materials. Wherein, the EVA resin is an ethylene-vinyl acetate copolymer, and the general vinyl acetate (VA) content is 5% to 40%. Both polyv...

Abstract

The invention relates to an amorphous silicon membrane photovoltaic module. The amorphous silicon membrane photovoltaic module comprises front plate glass, a front electrode, an absorbed layer, a back electrode, a back plate bonding layer, a back plate, tempered glass and a bonding layer, wherein the tempered glass is positioned on the outside of the front plate glass, and is connected with the front plate glass through the bonding layer in a bonding manner; the bonding layer is made from a transparent bonding material, is positioned between the tempered glass and the front plate glass, and is used for connecting the tempered glass and the front plate glass in the bonding manner; and the back plate is a heat dissipating back plate. The amorphous silicon membrane photovoltaic module is high in mechanical strength, has high mechanical safety performance and heat dissipation performance, can be applicable for using requirements in extreme conditions, and has extremely high universal applicability.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a large-area amorphous silicon thin-film photovoltaic module. Background technique [0002] A solar cell is a semiconductor optoelectronic device that directly converts sunlight energy into electrical energy by using the photovoltaic effect of the device. Compared with other commonly used energy sources, solar energy has very little pollution, and is an ideal clean and renewable energy source. [0003] As a kind of solar cell, stacked silicon-based thin-film solar cells are widely used due to their low cost, low energy consumption, no pollution, and their own high conversion efficiency and low attenuation compared to other thin-film solar cells. Manufacture and apply in production and life. [0004] At present, the stacked silicon-based thin film solar cell structure such as figure 1 As shown, it consists of the following parts: [0005] The front glass ①, specifically ul...
