Abstract
Provided is a sheet for a solar cell encapsulant containing (A) an ethylene-based polymer having a melting point of 90° C. or higher and containing an ethylene-derived constituent unit as a main component; (B) an ethylene-vinyl acetate copolymer having a vinyl acetate-derived constituent unit at a content ratio of from 19% to 40% by mass; and (C) a silane coupling agent having an amino group. The sheet for solar cell encapsulant has the excellent transparency and flexibility possessed by an ethylene-vinyl acetate copolymer. Furthermore, a crosslinking treatment is substantially unnecessary, and adhesiveness and adhesion stability that are appropriate for practical use are obtained.
