A BACKSHEET FOR PHOTOVOLTAIC MODULES

摘要

A backsheet (1) for a photovoltaic module (5) comprising a support (10) and a primer (11) provided on a side of the support facing a sealing layer (2'), the primer comprising an acrylic resin and a crosslinking agent, characterized in that the acrylic resin is a copolymer comprising at least 5 wt % of an acrylate monomer unit containing a UV absorbing group and at least 2 wt % of an acrylate monomer unit containing a crosslinkable group both relative to the total weight of monomer units.
