Dye-sensitized solar cell

A dye-sensitized solar cell comprising:

• a first substrate;
• a second substrate which faces the first substrate;
• a first electrode formed on a first surface of the first substrate, the first surface facing a second surface of the second substrate;
• an electron-collector/dye layer provided on the first electrode;
• a catalyst layer provided on the second surface, the catalyst layer having a diffusion/reflection surface which faces the first surface;
• and
• an electrode donor provided between the electron-collector/dye layer and the catalyst layer.
