摘要

To provide a titanium oxide paste using titanium oxide particles having excellent properties, a titanium oxide film, and a dye-sensitized solar cell having high photoelectric conversion efficiency without using TMAH.SOLUTION: A titanium oxide paste according to the present invention is a dispersion solution of titanium oxide particles containing a compound having a 5-membered ring containing titanium oxide particles and nitrogen, and the titanium oxide particles have a dispersion solution of titanium oxide particles in which a Scherrer diameter ratio (D/D) is 0.2 to 1.0, and a cumulant polydispersity index (PDI) of titanium oxide particles is 0.50 or less, a solvent, and a binder. The titanium oxide film according to the present invention can be obtained by forming the titanium oxide paste according to the present invention. Further, the dye-sensitized solar cell according to the present invention is composed of an optical semiconductor electrode in which the titanium oxide film carries a sensitizing dye.SELECTED DRAWING: None
