(57) Abstract: A photovoltaic cell capable of suppressing the dark current, suppressing the decomposition of a spectral sensitizing dye due to ultraviolet light, and having high photoelectric conversion efficiency and high electromotive force. provide. A substrate having an electrode layer (1) on a surface and a porous metal oxide semiconductor film (2) having a photosensitizer adsorbed on the surface of the electrode layer (1) is formed on the substrate. A substrate having an electrode layer (3) is disposed so that the electrode layer (1) and the electrode layer (3) face each other, and the porous metal oxide semiconductor film (2) and the electrode layer (3) are arranged. In the photovoltaic cell in which the electrolyte layer is provided between the substrate and (2), the porous metal oxide semiconductor film has (2) a dark current preventing component, and at least one of the substrate and the electrode layer has transparency. An opto-electric cell, comprising: |
