SOLAR CELL SEALING MATERIAL AND SOLAR CELL MODULE

摘要

PROBLEM TO BE SOLVED: To provide a solar cell sealing material which is excellent in adhesion to a metal electrode and a solder and long-term reliability under a constant temperature and constant humidity while having flexibility and heat resistance.SOLUTION: The solar cell sealing material contains: an ethylene/α-olefin copolymer; an organic peroxide; a silane coupling agent having at least one group selected from the group consisting of a vinyl group, a methacrylic group, and an acrylic group; and an epoxy group-containing silane coupling agent. Preferably, the content of the epoxy group-containing silane coupling agent is 0.05-2.0 pts.wt. based on 100 pts.wt. of the ethylene/α-olefin copolymer.
