A photovoltaic module comprises an active solar cell layer having a front light receiving side and opposite rear side, an encapsulant layer adhered to the rear side of the active solar cell layer, and a back-sheet adhered to the encapsulant layer. The back-sheet comprises a first polymer film adhered to said encapsulant layer, where the first polymer film comprises 20 to 95 weight percent chlorosulfonated polyolefin, such as chlorosulfonated polyethylene, based on the weight of the first polymer film, and 1 to 35 weight percent of adhesive based on the weight of the first polymer film. The first polymer film may further comprise 10 to 70 weight percent of inorganic particulates such as calcium carbonate, titanium dioxide, kaolin and clays.
