Abstract:
A solar battery includes a transparent electrode and a collector electrode in this order on the surface of a light incident surface side of a photoelectric conversion layer. The collector electrode is formed in a predetermined region on the photoelectric conversion layer and a first transparent electrode of the transparent electrode is formed only in a region right under the collector electrode in contact with the photoelectric conversion layer and the collector electrode. A second transparent electrode of the transparent electrode is formed in a region on the photoelectric conversion layer where the collector electrode is not formed and on the collector electrode in contact with the photoelectric conversion layer or the collector electrode. The carrier concentration of the first transparent electrode is higher than the carrier concentration of the second transparent electrode.
