TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Process: Preparation of the photovoltaic module comprising a multilayer laminate involves: (i) providing the solar cell layer; (ii) providing the first film layer (L1); (iii) providing the second film layer (L2) that is larger in area than the solar cell layer; (iv) contacting a modified surface of the first film layer with a first surface of the second film layer; (v) contacting the solar cell layer with the second film layer such that: the second surface of the second film layer contacts the solar cell layer, a portion of the second film layer extends beyond the perimeter of the solar cell layer, and the portion of the second film layer that extends beyond the perimeter of the solar cell layer contacts another layer that is an encapsulant layer; and (vi) adhering the second film layer to the first film layer and to the encapsulant layer by the application of heat and optionally pressure or vacuum to provide a photovoltaic module.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: In the process (M1), the modified surface of the first film layer (L1) is treated with an organosilane prior to contacting the surface of the second layer. In the process (M2), the encapsulant layer of the solar cell layer comprises a polymeric material selected from ethylene acid copolymers, ionomers of ethylene acid copolymers, ethylene vinyl acetate copolymers, poly(vinyl acetals), polyurethanes, polyvinylchlorides, polyethylenes, polyolefin block copolymer elastomers, copolymers of alpha-olefins and alpha,beta-ethylenically unsaturated carboxylic acid esters, silicone elastomers, and/or epoxy resins. An additional layer is adhered to the surface of the encapsulant layer that is opposite the surface that contacts the surface of the second film layer. Preferred Definitions:    R1=H;    R2=butyl;    R3=methyl.    SPECIFIC COMPOUNDS - 1 Compound is specified as olefin compound (I) i.e. butyl acrylate (Ia). 1 Compound is specified as olefin compound (II) i.e. glycidyl methacrylate.    EXAMPLE - A non-fluorinated terpolymer film (A1) for a multilayer laminate for a photovoltaic module comprising (wt.%): copolymerized ethylene units (66.75), copolymerized n-butyl acrylate units (28), and copolymerized glycidyl methacrylate units (5.25) (having melt flow rate (MFR) of 12 g/10 minutes at 190 degrees C, 2.16 kg as measured according to ASTM D 1238), was prepared. A fluorinated film (A2), comprising PV3251 (RTM: a fluorinated film corona treated on one side, comprising (wt.%): ethylene-tetrafluoroethylene (ETFE) copolymer copolymerized units tetrafluoroethylene (TFE) (76.5-80.1), copolymerized units ethylene (17.8-19.6) and copolymerized units perfluorobutylethylene (PFBE) (2.1-3.9)), was used as fluorinated resin film. The non-fluorinated polymer film (A1) sample was directly laminated to fluorinated copolymer resin film (A2) at 150 degrees C, the fluorinated copolymer resin film forming a flexible top sheet. A foil substrate was used as a bottom sheet. A laminator with a platen, enclosure and bladder was used as the lamination device. The laminate was evaluated for peel strength according to ASTM F 904-91. The peel strengths were as follows (mean lbf/inch): (initial adhesion): (23.520); after 1000 hours damp heat: (28.059); and after 2000 hours damp heat: (23.969).
