BACKSIDE SEALING SHEET FOR SOLAR BATTERY AND SOLAR BATTERY MODULE USING THE SAME

PROBLEM TO BE SOLVED: To provide a backside sealing sheet for a solar battery, which is excellent in sufficient adhesive strength with an EVA resin packed material layer, storage stability of a film roll, productivity, and further excellent in gas barrier property, weatherability, and excellent in light reflectivity even in use for a long term. SOLUTION: The backside sealing sheet for the solar battery is characterized by sequentially laminating, on one side of a laminated sheet on which a hydrolysis resistant resin film, a vapor shielding resin film, and a white resin film are laminated: an adhesive layer using an isocyanate group containing polymer as a cross-linking agent; and a thermal adhesive resin layer containing an ethylene based copolymerized resin.
