Abstract
A dye-sensitized photoelectric conversion apparatus having enhanced energy conversion efficiency and a production method thereof are provided. The dye-sensitized photoelectric conversion apparatus which has semiconductor layer () containing a photosensitizing dye () and is constituted such that a charge carrier generated by allowing light to incident in the photosensitizing dye () is drawn out through the semiconductor layer (), in which the semiconductor layer () is constituted by a plurality of regions (A toD) having different energy levels from one another of a passage through which the charge carrier is transferred. Further, the plurality of regions (A toD) are arranged such that the energy levels are reduced stepwise and/or continuously in the direction of drawing the charge carrier out.
