PURPOSE:To improve the practical conversion efficiency (modular efficiency) by increase of the area of a photoelectric conversion semiconductor layer by a method wherein a frame surrounding a module is formed of a transparent material. CONSTITUTION:The photoelectric conversion semiconductor layer 1, a solar battery element, formed on a glass plate 2 is covered with a protection resin layer 3 over the surface and produces photoelectromotive force with the light incident from the glass plate side. The frame 16 made of transparent plastic U-shaped in cross-section is provided in the periphery of the module via transparent acrylic sealing material 15. Since the photo energy penetrates through the transparent frame and the transparent sealing material, the semiconductor layer made of amorphous Si can be provided over the entire surface of the glass plate 2, and then the photoelectric conversion area can be increased. |
