SOLAR CELL SEALING MATERIAL, AND SOLAR CELL MODULE PREPARED BY USING SAME

摘要

Provided are a solar cell encapsulant material which facilitates production of solar cell modules, which does not require a crosslinking step and which is excellent in heat resistance and others, and a solar cell module produced by the use of the encapsulant material. The solar cell encapsulant material comprises a resin composition (C) that contains an olefin-based polymer (A) satisfying the following requirement (a) and an olefin-based polymer (B) satisfying the following requirement (b). (a) The crystal melting peak temperature of the polymer, as measured at a heating rate of 10°C/min in differential scanning calorimetry, is lower than 100°C. (b) The extrapolated onset temperature of melting of the polymer, as measured at a heating rate of 10°C/min in differential scanning calorimetry, is 100°C or higher.
