SOLAR BATTERY SEALING MATERIAL

摘要

This invention provides a solar battery sealing material, which facilitates the preparation of a solar battery module and is excellent, for example, in fabricability, insulating properties, noncorrosive properties, transparency, heat resistance, and flexibility, and a solar battery module prepared using the same. The solar battery sealing material comprises a crosslinkable resin composition (A) comprising an ethylene-(meth)acrylic ester copolymer as a base polymer, an organic peroxide and a crosslinking aid. The decomposition temperature (one-hr half-reduction period temperature) of the organic peroxide is 150ºC or below. The total amount of the organic peroxide and the crosslinking aid incorporated is in the range of 0.5 to 5 parts by weight based on 100 parts by weight of the base polymer. The mixing weight ratio between the organic peroxide and the crosslinking aid (organic peroxide/crosslinking aid) is in the range of 1/5 to 1/0.1.
