Claim:
1. A solar cell module, comprising: a plurality of back contact solar cells; an interconnector that electrically connects adjacent back contact solar cells serially; an upper protective layer, which is positioned on light receiving surfaces of the plurality of back contact solar cells; a lower protective layer, which is positioned on an opposite side of the light receiving surfaces of the plurality of back contact solar cells; a transparent member that is positioned on the upper protective layer; and a back sheet that is positioned under the lower protective layer, wherein the upper protective layer is positioned between the plurality of back contact solar cells and the transparent member, and the lower protective layer is positioned between the plurality of back contact solar cells and the back sheet, wherein the upper protective layer and the lower protective layer are formed of different materials from each other, wherein the lower protective layer is further positioned between the interconnector and the back sheet, wherein the upper protective layer is formed of ethylene vinyl acetate (EVA) of a film form, and the lower protective layer consists of a single layered cured siloxane, wherein the lower protective layer fills a space between the plurality of the back contact solar cells, and wherein the lower protective layer physically and directly contacts each of front and back surfaces of the interconnector in an area between the adjacent back contact solar cells.
