SOLAR CELL SEALING MATERIAL SHEET AND SOLAR CELL MODULE

摘要

The problem addressed by the present invention is providing an excellent quality solar cell sealing material sheet that suppresses variations in luster while maintaining the cushioning properties and degassing properties of the sealing material sheet. This solar cell sealing material sheet has 40 - 2300 protrusions per cm2 on at least one of the surfaces thereof and is formed from a thermoplastic resin. The solar cell sealing material sheet is characterized by the protrusions being constituted of a base part that has a pyramid frustum shape with a polygonal shape as the bottom surface and a top part that has a convex curved surface shape and by the top part proportion (X) of the protrusion being 0.1 - 0.4.
