Abstract

The invention discloses a fluorine-containing thin film solar cell front film and a manufacturing process thereof, A fluorine-containing thin film solar cell front film includes a fluorine-containingmaterial film layer, adhesive layer, inorganic deposit, an insulating layer arranged from top down in sequence. At least one of PVDF, PFA, ETFE, and EFEP is included in that film layer of the fluorine-containing material, at least one of silicon dioxide, aluminum oxide, and titanium dioxide is included in the inorganic deposition layer, and at least one of PET and PBT is included in the insulatinglayer. The fluorine-containing thin film solar cell front film has the advantages of high water resistance, high light transmittance, strong ultraviolet ray resistance, good insulation, not easy toage, high hardness, high strength, hydrolysis resistance and damp and heat resistance. The process of the invention can promote the bonding strength of the front film of the thin film solar cell, ensure that the front film of the thin film solar cell is resistant to adverse outdoor environment, and improve the use safety of the front film of the thin film solar cell.

Description

technical field [0001] The invention relates to the field of thin film technology, in particular to a fluorine-containing thin film solar battery front film and a manufacturing process thereof. Background technique [0002] The front film of thin film solar cells has excellent optical transmittance, water vapor barrier ability, dielectric strength, ultraviolet aging performance, bendability, wear resistance, etc., and can be used as a substitute material for the front glass of thin film solar cells. The front film of a thin-film solar cell is usually a laminated composite structure, mainly including an outer layer material (weather-resistant layer), an adhesive layer, a water-blocking material (inorganic deposition layer), and an inner layer material (insulation layer). [0003] The thin-film solar cell may be a silicon thin-film solar cell, an inorganic thin-film solar cell, a dye-sensitized solar cell, or an organic thin-film solar cell. [0004] Since thin-film solar cel...
