Patent ID: 8791208

Claim:
A sheet for a solar cell encapsulant, consisting of: (A) 50% to 90% by mass of an ethylene-based polymer having a melting point of 90° C. or higher and containing an ethylene-derived constituent unit as a main component, wherein (A) the ethylene-based polymer is an ethylene-vinyl acetate copolymer consisting of an ethylene-derived constituent unit and a vinyl acetate-derived constituent unit in which a content ratio of the ethylene-derived constituent unit is 88% or more by mass or an ethylene-acrylic acid ester copolymer consisting of an ethylene-derived constituent unit and an acrylic acid ester-derived constituent unit in which a content ratio of the ethylene-derived constituent unit is 94% or more by mass and a content ratio of the acrylic acid ester-derived constituent unit is 6% or less by mass; (B) 10% to 50% by mass of an ethylene-vinyl acetate copolymer having a vinyl acetate-derived constituent unit at a content ratio of from 19% to 40% by mass; (C) a silane coupling agent having an amino group; and optionally an ultraviolet absorbent, a light stabilizer, an antioxidant, a colorant, a light diffusing agent a frame retardant, or combinations thereof.
