FILLER LAYER FOR SOLAR CELL MODULE, SOLAR CELL MODULE AND RECLAIMABLE SOLAR CELL ELEMENT, AND MANUFACTURING METHOD FOR RECLAIMABLE TRANSPARENT FRONT SUBSTRATE

摘要

PPROBLEM TO BE SOLVED: To provide a manufacturing method of a filler layer for a solar cell module and a reclaimable solar cell element or a reclaimable transparent front substrate, for making it possible to recover reusable resources such as transparent front substrates, solar cell elements, etc. from constituting members, and recycle or reuse them. PSOLUTION: A filler layer for a solar cell module having a peel layer the main constituent of which is thermoplastic resin (a) whose peel strength measured in a 180 peel test in an atmosphere of 25C is in the range of 1 N/15 mm width to 150 N/15 mm width, (b) whose Vicat softening temperature measured based on JIS Standard K7206 is in the range of 60C to 128C, and (c) whose melt mass-flow rate measured based on JIS Standard K7210 is in the range of 0.1 g/10 min to 50 g/10 min, and (d) an output retention rate of photovoltaic power measured before and after the test according to the rules for a solar cell module using the filler layer is in the range of 80% to 100%.
