(57) [Summary] [PROBLEMS] To prevent electrons transferred to an oxide semiconductor electrode material from reacting with an electrolyte, to prevent a decrease in open-circuit voltage, Provided is a dye-sensitized solar cell capable of improving energy conversion efficiency. SOLUTION: In the dye-sensitized solar cell 1, at least a part of the oxide semiconductor fine particles (oxide semiconductor electrode material) 27 constituting the oxide semiconductor electrode 22 is made of aluminum oxide, magnesium oxide, nickel oxide, chromium oxide. , It is covered with a metal oxide film 26 made of at least one of manganese oxide, copper oxide, germanium oxide, gallium oxide, and zirconium oxide. Oxide semiconductor fine particles 27 Is at least one of tin oxide fine particles and antimony-containing tin oxide fine particles, or zinc oxide fine particles at least partially coated with at least one of tin oxide fine particles and antimony-containing tin oxide fine particles. It is desirable to become. |
