Abstract
A solar cell sealing film contains an ethylene-unsaturated ester copolymer, a crosslinker, and crosslinking auxiliary agents, wherein the solar cell sealing film contains a polyfunctional (meth)acrylate having 5 or more (meth)acryloyl groups in the molecule and triallyl isocyanurate as the crosslinking auxiliary agents, and a mass ratio of the polyfunctional (meth)acrylate to the triallyl isocyanurate is 0.06 to 0.3 parts of polyfunctional (meth)acrylate per 1 part of triallyl isocyanurate.
Claims6
A solar cell sealing film, comprising:
- ethylene-vinyl acetate copolymer,
- an organic peroxide, and
- crosslinking auxiliary agents,
- wherein the organic peroxide is 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane,
- wherein the solar cell sealing film comprises a polyfunctional (meth)acrylate having 6 (meth)acryloyl groups in the molecule and triallyl isocyanurate as the crosslinking auxiliary agents,
- a mass ratio of the polyfunctional (meth)acrylate to the triallyl isocyanurate is 0.06 to 0.3 parts of polyfunctional (meth)acrylate per 1 part of triallyl isocyanurate,
- a content of the triallyl isocyanurate is 0.5 to 3.0 parts by weight based on 100 parts by weight of the ethylene-vinyl acetate copolymer, and
- a content of the polyfunctional (meth)acrylate is 0.15 to 0.5 part by weight based on 100 parts by weight of the ethylene-vinyl acetate copolymer.
