ABSTRACT:
To reduce power loss in a transparent electrode with a high sheet resistance in a thin-film solar cell that uses an amorphous semiconductor layer, without having to use a complex patterning process. A large number of holes are formed through an insulating substrate, while a third electrode layer with a low sheet resistance is disposed on the rear side of the substrate and a transparent second electrode layer disposed on the light incidence side. The second and third electrode layers are connected to each other via said holes. To build a series-connection structure, an extended portion of the third electrode layer on one cell and extended portions of the first electrode layers on adjoining cells are connected to each other via similar holes formed on the substrate.
