PROBLEM TO BE SOLVED: To provide a solar cell module using an encapsulant sheet for solar cell module having a sufficient heat resistance, suppressing occurrence of crack in a solar cell element caused by a bus bar, having embeddability, and higher glass adhesiveness.SOLUTION: In an encapsulant sheet, the content of polyethylene having a density of 0.860-0.970 g/cmis 85% or more of the whole encapsulant composition. The encapsulant sheet has a degree of crosslinking which changes in the thickness direction of the encapsulant sheet, and the surface of the encapsulant sheet on the side of higher degree of crosslinking is located on the bus bar side of a solar cell element.SELECTED DRAWING: Figure 2 |
