<p>Disclosed is a method for preparing a dye-sensitized solar cell comprising forming a photoelectrode layer and adsorbing dye into the photoelectrode layer, wherein the method further comprises irradiating UV to the photoelectrode layer before the adsorption of the dye. According to the method, remaining organic substance and contaminant in the photoelectrode layer are decomposed and removed by the UV irradiation, and the material forming the photoelectrode layer itself functions as a photocatalyst, and thus, if electrons are excited by the UV irradiation, surrounding H 2 O or O 2 takes the electrons to decompose surrounding organic substance, to wash the surface of the photoelectrode layer before the adsorption of dye thereby improving adsorption efficiency, and the photoelectrode layer is activated by the UV irradiation to facilitate adsorption thereby also increasing dye adsorption efficiency, thus largely improving dye adsorption efficiency in two ways, to improve photoelectric conversion efficiency of a solar cell.</p> |
