Disclosed is a titanium oxide structure that, by virtue of a series of titanium oxide particles connected to one another, has a large surface area and can realize an efficient movement of ions and electrons. Also disclosed are a material useful as an active material for a dye-sensitized solar cell, a process for producing the material, a porous titanium oxide composition, a process for producing the porous titanium oxide composition, and a photoelectric conversion element using the titanium oxide structure or the porous titanium oxide composition. |
