Zusammenfassung: | A film has an inner and an outer surface. The film includes a first layer forming the outer surface and including fluoropolymer. The film further includes a second layer disposed away from the outer surface comprising a polymer. The polymer can have a storage modulus at 65° C. of at least 5 MPa. The film has a plurality of surface features forming the outer surface and extending into the first and second layers. The surface features have a mean slope of at least 15°. The film can be applied as a protective film overlying an active component of a photovoltaic device. |
