NOVELTY - A photoelectric conversion element (10) consists of a photoelectric conversion layer (6), a substrate (1), a primary electrode (2), a positive hole transport layer (7) containing a conductive polymer, and a secondary electrode (8). The photoelectric conversion layer contains semiconductor (5) and sensitizing dye (4). The positive hole transport layer is obtained by contacting primary electrode and electron acceptor, contacting photoelectric conversion layer and electroconductive high-molecular precursor, and polymerizing the electroconductive high-molecular precursor.    USE - Photoelectric conversion element is used for dye-sensitized solar cell used in generation of electric power.    ADVANTAGE - The photoelectric conversion element has excellent durability and optical characteristics.    DETAILED DESCRIPTION - A photoelectric conversion element consists of a photoelectric conversion layer, a substrate, a primary electrode, a positive hole transport layer containing a conductive polymer, and a secondary electrode. The photoelectric conversion layer contains semiconductor and sensitizing dye. The positive hole transport layer is obtained by contacting primary electrode and electron acceptor, contacting photoelectric conversion layer and electroconductive high-molecular precursor, and polymerizing the electroconductive high-molecular precursor by irradiating light with respect to photoelectric conversion layer. An INDEPENDENT CLAIM is included for manufacture of photoelectric conversion element, which involves forming the photoelectric conversion layer on the primary electrode, and forming the positive hole transport layer.
