ABSTRACT:
A thermoplastic film or sheet having a thickness of about 1 mil (0.026 mm) to about 20 mils (0.51 mm) containing a surface embossed layer comprising a copolymer of alpha olefin(s) with alpha, beta ethylenically unsaturated carboxylic acid comonomer(s), ionomers derived therefrom and combinations thereof useful for making solar cell laminates, wherein the surface is embossed with a pattern which provides channels for de-airing, the channels having depth of about 20 microns or less, a width of about 30 microns to about 300 microns and spaced about 0.1 mm to about 1 mm apart, and use thereof in photovoltaic cells and the manufacture thereof.
