Abstract: A solar cell module comprises a solar cell assembly and a reflecting back encapsulant that is laminated to the back non-sun-facing side of the solar cell assembly. The reflecting back encapsulant comprises a co-extrusion or extrusion coated multilayer sheet, and the multilayer sheet comprises a reflecting layer, a first tie layer and optionally a second tie layer that are co-extruded or extrusion coated on the reflecting layer. The multilayer sheet has a total thickness of about 2 to about 50 mil (about 51 to about 1270 ?m). The tie layer(s) comprise polymeric material(s) that have a melting temperature of about 80° C. to about 165° C. and an adhesion to glass of at least about 30 lb/inch when measured with the T-peel test. The reflecting layer has a thickness of about 1 to about 35 mil (about 25 to about 889 ?m); comprises a polymeric material having a melting temperature between 80° C. and 165° C.

Abstract: Provided herein are multilayer film structures that may be used in packaging applications, for example. The multilayer film structures include a first metallized thermoplastic film and a second thermoplastic film. These first and second films are joined directly to each other over at least a portion of their surface area to form a laminate having the structure “first thermoplastic film/metallic layer/second thermoplastic film”. The thermoplastic layers of the films may be the same or different and comprise one or more ethylene acid copolymers or ionomers thereof. The first metallized thermoplastic film has an optical density of 3 or less. When the first metallized thermoplastic film and the second thermoplastic film are joined by heat sealing to form the structure “thermoplastic film/metallic layer/thermoplastic film”, its internal seal strength is at least about 4 N/15 mm.
