A co-extruded multi-layer biaxially oriented polyester film comprising a primary polyester layer and a dissimilar secondary polyester layer adjacent to the primary polyester layer, wherein the primary polyester layer and the secondary polyester layer each comprise a glycidyl ester of a branched monocarboxylic acid, wherein the monocarboxylic acid has from 5 to 50 carbon atoms, and wherein said glycidyl ester is in the form of its reaction product with at least some of the end groups of the polyester; and use thereof as a component of a photovoltaic cell.

Co-extruded multi-layer polyester films having hydrolytic stability and improved delamination resistance

A composite film comprising: (i) a heat-stabilised oriented polyester substrate comprising a UV-absorber in an amount of from about 0.1 to about 10% based on the total weight of the polyester substrate, and (ii) on one or both surfaces of the substrate a polymeric coating layer, which has a thickness in the range of from about 10 nm to about 200 nm, and which comprises an ethylene acrylic acid (EAA) copolymer, wherein the composite film exhibits a shrinkage at 150&#xb0; C. for 30 minutes of less than 0.1% in both the longitudinal and transverse dimensions of the film, and use thereof in the manufacture of photo-voltaic cells.
