Photovoltaic cells with improved backsheet

A polyamide-ionomer blend composition comprising

• (i) A polymer component comprising
• 1) 53 to 64 weight %, based on the combination of (1) and (2), of a polyamide component comprising a polyamide having at least one repeating unit with 7 to 12 carbon atoms;
• 2) 36 to 47 weight %, based on the combination of (1) and (2), of an ionomer comprising a copolymer of
• (a) ethylene;
• (b) from 2 weight % to 30 weight % of an alpha, beta-unsaturated C3-C8 monocarboxylic acid wherein the carboxylic acid functionalities present are at least partially neutralized to carboxylate salts of one or more alkali metal, transition metal, or alkaline earth metal cations;
• and
• (ii) 0 to 20 weight % of pigment;
• (iii) 0 to 40 weight % of filler;
• wherein the combination of (ii) and (iii) comprises 8 to 50 weight % of the combination of (i), (ii), (iii) and (iv);
• and
• (iv) 0 to 5 weight % of additives selected from oxidation inhibitors, UV stabilizers and hindered amine light stabilizers.
