SEAL-MATERIAL COMPOSITION FOR SOLAR BATTERY MODULE, SEALANT, AND SOLAR BATTERY MODULE

摘要

PROBLEM TO BE SOLVED: To provide a sealant for a non-light receiving surface side of a solar battery module, which can contribute to the enhancement of a heat dissipation performance of a solar battery module, and which can prevent a solar battery module power generation efficiency from being lowered.SOLUTION: A seal-material composition for a solar battery module comprises: a base resin (A); a thermally conductive resin(B); and thermally conductive inorganic particles (C). The base resin (A) is a polyethylene-based resin having a density of 0.870 to less than 0.930 g/cm, of which the content in the seal-material composition is 50-90 mass%. The thermally conductive resin(B) is a thermoplastic resin having a density of 0.930 to 0.980 g/cm, of which the content in the seal-material composition is 10-50 mass%. The thermally conductive inorganic particles (C) are made of an inorganic substance having a thermal conductivity of 1 W/mK or larger, of which the content in the seal-material composition is 6-35 mass%.SELECTED DRAWING: Figure 1
