The invention discloses a dye-sensitized solar cell structure. The dye-sensitized solar cell structure comprises a conductive glass substrate, wherein a nanoporous semiconductor thin film is attached to the bottom of the conductive glass substrate; the film surface at the bottom of the nanoporous semiconductor thin film is adsorbed with a dye sensitizer layer; the bottom of the conductive glass substrate is covered with an N type semiconductor; the top surface of the N type semiconductor is adsorbed with the nanoporous semiconductor thin film; an electrolyte is arranged between the N type semiconductor and the conductive glass substrate; and the electrolyte is in full contact with the nanoporous semiconductor thin film on the N type semiconductor and the dye sensitizer layer on the conductive glass substrate separately. Compared with the conventional dye-sensitized solar cell adopting a solid platinum metal counter electrode, the reduction reaction speed on the electrolyte of the dye-sensitized solar cell pro
