<p>PURPOSE: A paste for dye-sensitized solar cell photo-electrode can control the porosity of semiconductor oxide layer in a photo-electrode, so that the optical transmittance rate of photo-electrode and photoelectric conversion efficiency are improved. CONSTITUTION: A paste for dye-sensitized solar cell photo-electrode contains semiconductor oxide particles, a binder, a solvent, and a polymer resin particles. The polymer resin particles are refractory in the solvent and can be oxidized and removed at an oxygen atmosphere of 400-600°C. In the semiconductor oxide particles, a first semiconductor oxide particle has an average diameter of 7-12 nm, a second semiconductor oxide particle has an average diameter of 13-20 nm, and a third semiconductor oxide particle has an average diameter of 40-60 nm. The polymers resin particles include polymer resin particles with thermosetting property.
