US 8,999,508 B2 · Back sheet of solar cell and manufacturing method thereof

Abstract

A back sheet of solar module with high adhesivity comprises a substrate (3), a layer of fluorine-based film (2), and a layer of fluoro-silicone film (1) or titanium-silicon film (4) formed between the layer of fluorine-based film (2) and the substrate (3), as well as on outer surface of the layer of fluorine-based film (2). A method for manufacturing the back sheet of solar module comprises the treatment on the layer of fluorine-based film (2) and/or substrate (3) with compound of fluoro-silicone or titanium-silicon, so as to coat a layer of fluoro-silicone film (1) or titanium-silicon film (4).

Claims19

Dependent claims

A back sheet for attachment to a solar module comprising

a substrate,
a layer of fluorine-based film defining a top surface and a bottom surface, one of which faces toward the substrate, and
fluoro-silicone material associated with the fluorine-based film and appearing at the top and bottom surfaces of the film, wherein the layer of fluorine-based film is tetrafluoroethylene homopolymer, a ternary copolymer, or chlorotrifluoroethylene, and wherein said ternary copolymer includes C2F4, C3F6, and PVDF, such that when the back sheet is attached to said solar module the fluoro-silicone material is in direct contact with said solar module.

Dependencies are inferred from the claim text.
