Photovoltaic module using PVDF based flexible glazing film

A photovoltaic module, comprising, in order from front to back:

• a) a transparent polyvinylidene fluoride (PVDF) glazing exterior layer exposed to solar radiation, consisting of a polyvinylidene fluoride/hexafluoropropene copolymer comprising 5-40 mole percent of hexafluoropropene and at least 60 mole percent of vinylidene fluoride monomer units, and having a melting point of from 145° C. to 167° C., and optional additives wherein said transparent polyvinylidene fluoride glazing exterior layer has a thickness of from 5 to 50 microns;
• b) an interior layer comprising a material capable of converting solar radiation into electrical energy and encapsulated in an encapsulant selected from the group consisting of ethylene vinyl acetate, thermoplastic encapsulants based on alpha olefin ionomers, silicones and polyvinyl butyral;
• and
• c) a back sheet comprising a layer consisting of a material selected from the group consisting of polyvinyl fluoride, an ionomer/nylon alloy, polyethylene terephthalate polyethylene naphthalate, and polyvinylidene fluoride,
• wherein said photovoltaic module is flexible, and wherein transparent polyvinylidene fluoride glazing exterior layer is directly attached to said encapsulant.
