Solar cell module having surface coating material of three-layer structure

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