NOVELTY - A multilayer structure has layer(s) comprising a polyamide-ionomer blend composition comprising pigment, filler, additive and polymer component containing 53-64 wt.% polyamide comprising nylon-6 and 36-47 wt.% ionomer, 2-30 wt.% ( alpha ),( beta )-unsaturated 3-8C monocarboxylic acid, 0-12 wt.% co-monomer including dicarboxylic acid, and 0-30 wt.% monomer chosen from alkyl acrylate and alkyl methacrylate in which alkyl groups have 1-12 carbon atoms. The carboxylic acid functionalities are neutralized to carboxylate salts containing alkali metal, transition metal, and/or alkaline earth metal cation.    USE - Multilayer structure is used as backsheet in photovoltaic module e.g. laminated solar cell module (all claimed).    ADVANTAGE - The multilayer structure has excellent transparency, stiffness, moisture barrier properties, thermal contact and tensile properties.    DETAILED DESCRIPTION - A multilayer structure consists of layer(s) comprising a polyamide-ionomer blend composition comprising a polymer component, 0-20 wt.% pigment, 0-40 wt.% filler, and 0-5 wt.% additives chosen from oxidation inhibitors, ultraviolet stabilizers and hindered amine light stabilizers. The polymer component comprises 53-64 wt.% polyamide and 36-47 wt.% ionomer containing a copolymer of copolymerized units of ethylene, 2-30 wt.% (preferably, 5-15 wt.%) ( alpha ),( beta )-unsaturated 3-8C monocarboxylic acid, 0-12 wt.% (preferably, 0.5-12 wt.%) co-monomer(s) including ethylenically unsaturated dicarboxylic acid or their derivative chosen from maleic acid, fumaric acid, itaconic acid, maleic anhydride and 1-4C alkyl half ester of maleic acid, and 0-30 wt.% monomers chosen from alkyl acrylate and alkyl methacrylate in which alkyl groups have 1-12 carbon atoms. The carboxylic acid functionalities are at least partially neutralized to carboxylate salts containing alkali metal, transition metal, and/or alkaline earth metal cation. The polyamide comprises nylon-6. The total content of pigment and filler is 8-50 wt.% with respect to total weight of the composition. INDEPENDENT CLAIMS are included for the following:    (1) assembly for conversion under heat and pressure into a laminated solar cell module;    (2) laminated solar cell module; and    (3) manufacture of a solar cell module.
