Title:
PROTECTIVE FILM FOR SOLAR CELL MODULES, AND SOLAR CELL MODULE USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/007212
Kind Code:
A1
Abstract:
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 thermally fusion bonding resin layer; and a synthetic resin that is a main component of the thermally fusion bonding resin layer is crosslinked by irradiation of an electron beam. The thermally fusion bonding resin layer preferably contains a crosslinking agent. The synthetic resin is preferably a polypropylene. 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). This protective film for solar cell modules is preferably formed only of the thermally fusion bonding resin layer. The thermally fusion bonding resin layer preferably has an average thickness of from 40 μm to 500 μm (inclusive).
