Embodiment Construction

[0011] See figure 1 , A solar cell module with purification function, including TiO2 coating 1, tempered glass 2, upper EVA material layer 3, cell 4, lower EVA material layer 5 and back sheet 6, tempered glass 2, upper EVA material layer 3. The cell 4, the lower EVA material layer 5 and the back plate 6 are stacked in sequence from top to bottom. The TiO2 coating 1 is sprayed on the upper surface of the tempered glass 2, and the upper and lower EVA material layers 3 and 5 are extruded by a laminator After the high temperature generated during pressing melts, the tempered glass 2, the battery sheet 4 and the back plate 6 are glued together.

[0012] In the present invention, the TiO2 coating 1 is a nano-level coating.

Abstract

The invention discloses a solar cell module having a purifying function. The solar cell module includes a TiO2 coating, a piece of toughened glass, an upper EVA material layer, a cell sheet, a lower EVA material layer and a back plate, the toughened glass, the upper EVA material layer, the cell sheet, the lower EVA material layer and the back plate are successively piled up from the top to the bottom, the TiO2 coating is sprayed on the upper surface of the toughened glass, and the upper and lower EVA material layers are fused together by the high temperature to bond the toughened glass, the cell sheet and the back plate together. The solar cell module has the effect of air purification, and for the solar cell module itself, the ultraviolet ray intake is effectively reduced, the aging rate of the solar cell module is reduced, and the service life of the solar cell module is improved.

Description

Technical field [0001] The invention relates to the field of solar cells, in particular to a solar cell component with purification function. Background technique [0002] At present, the coated glass used in the photovoltaic industry mostly adopts a polymer with Si-O bonds as the main chain and organic groups directly connected to the silicon atoms. After the film is formed, SiO2 is combined with the glass substrate. Ultraviolet rays from nature can penetrate the coated glass to reach the inside of the module, which will destroy the molecular structure of the EVA and backplane, and cause the module to age. Summary of the invention [0003] The purpose of the present invention is to provide a solar cell module with purification function, which has the function of purifying air. [0004] The technical scheme of the present invention is as follows: [0005] A solar cell module with purification function, comprising a TiO2 coating, tempered glass, an upper EVA material layer, a battery...
