SONNENZELLENMODUL MIT EINEM OBERFLÄCHEN-ÜBERZUGSSTOFF VON DREISCHICHTENSTRUKTUR

摘要

A solar cell module of the type wherein a photovoltaic device (solar cell) is covered with a packing material, and its light-receiving side is covered with a three-layer structure. The three-layer structure comprises a rigid resin layer having a Shore hardness D of at least 50; an adhesive layer that absorbs UV rays of wavelenghts capable of deteriorating the rigid resin layer but transmits UV rays necessary for power generation by the photvoltaic device, and an outermost layer having high weatherability (the property that the resin itself is stable against heat, light and moisture).
