SOLAR CELL SEALING MATERIAL AND SOLAR CELL MODULE PRODUCED BY USING SAME

摘要

Provided are a solar cell sealing material with which solar cell modules can be formed easily and that has excellent adhesiveness, transparency, heat resistance, and long-term stability in adhesive force, and a solar cell module produced by using the solar cell sealing material. The solar cell sealing material includes at least an adhesive layer (layer (I)) and a layer (layer (II)) made of a resin composition (C) that contains an ethylene-a-olefin random copolymer (A) satisfying the following condition (a) and an ethylene-a-olefin block copolymer (B) satisfying the following condition (b). (a) The crystal melting heat quantity measured at a heating rate of 10°C/minute in differential scanning calorimetry is 0 to 70 J/g. (b) The crystal melting peak temperature measured at a heating rate of 10°C/minute in differential scanning calorimetry is 100°C or higher, and the crystal melting heat quantity is 5 to 70 J/g.
