The present invention relates to a method for manufacturing a high efficiency photoelectrode for a dye-sensitive solar cell, and more specifically, to a method for manufacturing a high efficiency photoelectrode for a dye-sensitive solar cell that includes injecting gas during dye absorption. The method of the present invention can allow dye to be very quickly absorbed, thus manufacturing a photoelectrode in a short time. A dye-sensitive solar cell including a photoelectrode manufactured by the method has a low recombination frequency of electrons inside a transition metal oxide layer coated on a conductive substrate and oxide ionic in an electrolyte to have a relatively higher probability of electric charge collection as compared to the prior art, resulting in increasing photoelectric conversion efficiency. Thus, a solar cell having excellent efficiency can be manufactured in a short time. The method comprises the steps of: dipping a conductive substrate coated with a transition metal oxide into a photosensitive dye solution; and directly injecting gas, which is not dissolved by the dye solution, in the dye solution for 30 mins to 2 1/2 hours to absorb dye in the transition metal oxide coated on the conductive substrate. |
