PHOTOELECTRIC CONVERSION ELEMENT USING PEROVSKITE COMPOUND AND METHOD OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a solid-junction solar cell as an alternative to a dye-sensitized solar cell inferior in durability and an organic thin-film solar cell inferior in light resistance and moisture resistance.SOLUTION: A solid-junction photoelectric conversion element has a photoelectric conversion layer between a pair of transparent electrode substrates each comprising a transparent substrate and a transparent electrode layer formed on the transparent substrate. In the photoelectric conversion layer, a first semiconductor layer obtained by depositing or adsorbing an organic-inorganic hybrid perovskite compound A onto the surface of a porous semiconductor fine particle layer formed on the electrode substrates and a second layer comprising carbon nanotubes which is formed as a film or an adsorbed body comprising an inorganic perovskite compound B and/or an organic-inorganic hybrid perovskite compound C are joined together.
