TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The organic resin layer thickness or the solar cell device side of (I) is 5-30 microns thick and is 10-50 microns thick on the opposite side. The resin layer contains fine particles of a metal or metal oxide on the side opposite to the solar cell device. A portion of (I) extends towards the outside of the circumferential part of the solar cell device and the transparent member and the encapsulating material, preferably ethylene-vinyl acetate copolymer (EVA) containing an ultraviolet absorber. (I) is iron or stainless steel and the transparent member is a 15-200 microns thick organic resin film, preferably of a fluororesin. The photovoltaic device comprises a semiconductive layer having at least a thick film of amorphous silicon as a light converting member on an electroconductive substrate, and a transparent electrode layer (I) is a plate like member having a bent portion, that is located outside of a region where the solar cell device is disposed. The organic resin layers on (I) have a common main component. The transparent member is a rigid, transparent member, preferably glass whereby the gap between a filler and (I) is not more than 1.5 mm. The transparent member is smaller than (I) and (I) is bent where it is larger than the rigid transparent member. The organic resin layer on the side opposite to the solar cell device has enhanced weather resistance and is of a different resin to that on the solar cell device side. The organic resin on the solar cell device side of (I) is a polyester resin, silicone polyester resin, epoxy resin, or urethane resin and is polyester resin, silicone polyester resin, acrylic resin, acrylic silicone resin, silicone resin or fluororesin. EXAMPLE - A solar cell module was fabricated using a stainless steel sheet reinforcing plate (0.4 mm thick) having a 8 micron thick polyester based paint layer on the device side and a 15 micron thick silicone polyester based paint layer on the opposite side. The reinforcing plate showed no change in appearance after 900 cycles of salt spray, 5000 hours in a sunshine weatherometer, 1000 hours at 85 degreesC and 85% relative humidity. In comparison a solar cell module fabricated with the reinforcing plate upside down showed paint blistering and peeling after the corrosion resistance and humidity tests.
