摘要:
A solar cell module, with excellent transparency, scratch resistance, weather resistance, and flame retarding property, is obtained by covering the outermost surface with a surface covering material comprising a trifluorochloroethylene-vinyl copolymer, and employing a hard film as part of the surface covering material under the trifluorochloroethylene-vinyl copolymer. The hard film and trifluorochloroethylene-vinyl copolymer are laminated and adhered with a filler to the photovoltaic element of the solar cell module.

A solar cell module in which at least the light receiving surface side of a photovoltaic element is coated with a filler, characterized in that the filler is made of a composition containing vinylidene fluoride copolymer and acrylic resin. The solar cell module is excellent in weather resistance, heat resistance, adhesion to a photovoltaic element (solar cell), and scratch resistance. Moreover, it is capable of minimizing the deterioration of the performance of the solar cell due to moisture permeability, thereby achieving a desirable photoelectric conversion efficiency over a long period of time.

摘要:
A light-transmissive resin sealed semiconductor is provided which is sealed at least at a light incident face of a photoelectric transducer with an organic polymer resin layer, which comprises a copolymer of ethylene and an unsaturated fatty acid ester. This light-transmissive resin sealed semiconductor has a surface layer which has high heat resistance, and low hygroscopicity, and does not liberate a free acid even in the presence of moisture. Thereby the semiconductor is prevented from deterioration of performances caused by the drop of the shunt resistance of the photovoltaic element under high humidity environment.
