A device includes: a substrate; a first cell region including a first lower electrode, a first photoelectric conversion layer containing a perovskite compound, and a first upper electrode; a second cell region including a second lower electrode, a second photoelectric conversion layer containing a perovskite compound, and a second upper electrode; and an inter-cell region including a first groove which separates the lower electrodes from each other, a second groove which separates the photoelectric conversion layers from each other, a conductive part which electrically connects the first upper electrode and the second lower electrode, and a third groove which separates the upper electrodes from each other. At least either the substrate including the first and second lower electrodes, or the first and second upper electrodes are formed of a light transmissive material. A member is disposed on the light transmissive material side.
