PROBLEM TO BE SOLVED: To provide a photoelectric conversion element that can obtain excellent photoelectric conversion efficiency even when a second electrode having translucency is used.SOLUTION: A photoelectric conversion element includes: a first substrate; a first electrode having translucency which is arranged on the first substrate; a photoelectric conversion layer which is arranged on the first electrode; a second electrode having translucency which is arranged on the photoelectric conversion layer; a porous layer which is arranged on the second electrode; and a second substrate which is arranged on the porous layer. The porous layer includes light scattering particles composed of a metal oxide.SELECTED DRAWING: Figure 1 【課題】透光性を有する第二の電極を用いても良好な光電変換効率が得られる光電変換素子を提供することを目的とする。【解決手段】第一の基板と、前記第一の基板上に配置された透光性を有する第一の電極と、前記第一の電極上に配置された光電変換層と、前記光電変換層上に配置された透光性を有する第二の電極と、前記第二の電極上に配置された多孔質層と、前記多孔質層上に配置された第二の基板とを有し、前記多孔質層は金属酸化物からなる光散乱粒子を含むことを特徴とする光電変換素子。【選択図】図１
