中文摘要	Electrochemical impedance spectroscopy and cyclic voltammetry were used to investigate the effect of various inorganic particles, including titania, alumina, zirconia with particle sizes ranging from nano- to micro-meter on electrochemical properties of the electrolyte used in dye-sensitized solar cell. Adding inorganic particles could improve the ionic transport Of 13 in the electrolyte and reduce the electrolyte-electrode transfer resistance, leading to an improvement of the photoelectric conversion efficiency of the devices. It was proposed that the improvement could be attributed to the interfacial effect between the inorganic particles and the electrolyte; ionic conduction paths formed between the solid particles facilitate the diffusion of the 13 in the electrolyte and improve the connection between the electrolyte and the electrode. Combined with a less volatile solvent system and a proper amount of the inorganic particles as the additive, an overall efficiency of 5.5% for the DSC (1 cm(2)) with P25 (10%) under 100 MW/cm(2) at room temperature was achieved, an improvement of 51% over that without the oxide additive.
