PROTECTIVE FILM FOR SOLAR CELL MODULES, AND SOLAR CELL MODULE USING SAME

WIPO Patent Application WO/2014/007211

A1

The purpose of the present invention is to provide: a protective film for solar cell modules, which is capable of preventing defects during thermal fusion bonding; and a solar cell module which uses the protective film for solar cell modules. A protective film for solar cell modules of the present invention is provided with a base layer that is formed of a synthetic resin and a thermally fusion bonding resin layer that is laminated on one surface of the base layer. A synthetic resin that is a main component of the thermally fusion bonding resin layer is crosslinked by irradiation of an electron beam. The synthetic resin is preferably a polyethylene. The thermally fusion bonding resin layer preferably contains a crosslinking agent. The thermally fusion bonding resin layer preferably contains a pigment in a dispersed state. The irradiation dose of the electron beam is preferably from 5 kGy to 300 kGy (inclusive). It is preferable that a hydrolysis-resistant layer is provided on the other surface of the base layer. It is also preferable that a gas barrier layer is additionally provided on the other surface of the base layer.
