Abstract:
1. A photoelectric conversion device comprising: a substrate; a plurality of photoelectric conversion cells located on the substrate, respectively, each of the photoelectric conversion cells comprising a lower electrode on the substrate comprising a metal element, a photoelectric conversion layer comprising a chalcogen compound semiconductor, the photoelectric conversion layer being located on the lower electrode, and an upper electrode located on the photoelectric conversion layer, a connection conductor electrically connecting, in neighboring ones of the photoelectric conversion cells, the upper electrode of one photoelectric conversion cell to the lower electrode of the other photoelectric conversion cell; and a first metal-chalcogen compound layer between the lower electrode and the connection conductor comprising the metal element and a chalcogen element included in the chalcogen compound semiconductor, wherein the connection conductor comprises a first connection portion and a second connection portion, the first connection portion being connected to the lower electrode through the first metal-chalcogen compound, the second connection portion being connected to the lower electrode of the neighboring photoelectric conversion cell without interposition of the first metal-chalcogen compound layer, the first connection portion and the second connection portion being located on an upper surface of the lower electrode.
