Multilayer structures useful as backsheets for electronic devices, for example photovoltaic cells, include (A) a top layer comprising a polyolefin resin, for example ethylene vinyl acetate, and having a top facial surface and a bottom facial surface, (B) an adhesive, For example, a first tie layer comprising ethylene glycidyl methacrylate and having an upper facial surface and a lower facial surface, the upper facial surface of which is attached in contact with the lower facial surface of the upper layer; and (C ) A lower layer comprising a polyolefin having at least one melting peak above 125 ° C., for example polypropylene, and having an upper facial layer and a lower facial surface, the upper facial surface of which is the lower facial surface of the first tie layer. In contact with the contact surface). |
