Patent ID: 8872019

Claim:
A photovoltaic module, comprising a laminate made from a) a transparent front cover, b) one or more photosensitive semiconductor layers, c) at least one plasticiser-containing, polyvinyl acetal-based film, and d) a rear cover, wherein the plasticiser-containing, polyvinyl acetal-based film c) has a UV transmission at 280 to 380 nm greater than 35%, determined between two panels of white glass, each 2 mm thick in accordance with EN410; and wherein the plasticiser-containing, polyvinyl acetal-based film contains, relative to the overall film mixture in each case, less than 0.01% by weight aromatic UV absorbers, and 0.005 to 1% by weight sterically hindered amines (HALS) and/or sterically hindered aminoethers (NOR-HALS) as non-aromatic photoprotection agents.
