Abstract: The purpose of the present invention is to provide a manufacturing method of a dye-sensitized solar cell using zinc oxide nanoparticles which are synthesized through a plasma process and a dye-sensitized solar cell. For the purpose, the present invention provides a manufacturing method, of a dye-sensitized solar cell using zinc oxide nanoparticles, which comprises: a step (step 1) of generating plasma jet inside of a thermal plasma reactor; a step (step 2) of melting zinc oxide particles into the inside of the generated plasma jet and evaporating the zinc oxide particles; a step (step 3) of synthesizing zinc oxide nanoparticles by injecting mixed gas of oxygen and carbon dioxide gas into the plasma jet, activating the evaporated zinc gas and reaction gas and cooling the mixed gas; a step (step 4) of manufacturing a photoelectrode using the zinc oxide nanoparticles which are synthesized in the step 3; and a step (step 5) of manufacturing a dye-sensitized solar cell having the photoelectrode which is manufactured in the step 4. Also, a dye-sensitized solar cell which is manufactured using the method is provided. The present invention is capable of manufacturing a dye-sensitized solar cell which has the excellent conversion efficiency by introducing zinc oxide nanoparticles, which are manufactured by using mixed gas of oxygen and carbon dioxide as reaction gas, to a photoelecgtrode of the dye-sensitized solar cell.
