Abstract

The present invention relates to a solar cell backsheet, comprising a functional layer wherein the functional layer comprises a polyethylene alloy and a semi-crystalline polymer such as polypropylene, preferably at least 10 wt % of polypropylenes based on the total weight of the polymers in the functional layer. The polypropylene is selected from a polypropylene homo- or copolymer, the copolymer is a random or block copolymer. The polyethylene alloy comprises a copolymer containing an ethylene segment (—CH2-CH2-) which is selected from one or more of ethylene acrylate copolymer, ethylene-hexene copolymer, ethylene-octene copolymer, ethylene-vinyl acetate copolymer. The functional layer further comprises an inorganic filler selected from one of calcium carbonate, titanium dioxide, barium sulfate, mica, talc, kaolin, glass microbeads and glass fibers. The present invention also relates to a photovoltaic module comprising the backsheet according to the present invention.
