Abstract:
A solar cell module comprising a photovoltaic element having a light receiving face on which a collecting electrode comprising a metallic wire covered by an electrically conductive coat and a surface side cover comprising a filler of a copolymer of ethylene and an unsaturated acid ester and a surface protective film sequentially laminated on the light incident side of said photovoltaic element, wherein a resin layer comprising a resin material selected from the group consisting of an acrylic resin, a silicone resin, a fluorine-containing resin, mixtures thereof and an inorganic polymer is interposed between said photovoltaic element and said filler such that gaps present in said conductive coat of the collecting electrode are filled by said resin layer to prevent moisture invasion from damaging said metallic wire, wherein said resin layer has a moisture permeability of less than 20 g/m.sup.2.multidot.day in an atmosphere of 40.degree. C. and 90% RH.
