The present invention relates to a metal-oxide/carbon-nanotube composite membrane to be used as a P-type conductive membrane for an organic solar cell, to a method for preparing same, and to an organic solar cell having improved photovoltaic conversion efficiency using the same. More particularly, the present invention relates to a metal-oxide/carbon-nanotube composite membrane to be used as a P-type conductive membrane for an organic solar cell, wherein said composite membrane is prepared by dispersing single-walled carbon nanotubes in an organic solvent, adding metal oxides to the mixed solution, dispersing the mixed solution to obtain a composite solution, and depositing the thus-obtained composite solution onto a substrate. The method also relates to a method for preparing a metal-oxide/carbon-nanotube composite membrane to be used as a P-type conductive membrane of an organic solar cell, comprising: a step (step 1) of dispersing single-walled carbon nanotubes in an organic solvent; a step (step 2) of adding metal oxides to the mixed solution prepared in step 1, and dispersing the mixed solution to obtain a composite solution; and a step (step 3) of depositing the thus-obtained composite solution onto a substrate. The present invention also relates to an organic solar cell formed by laminating components in the following order: a substrate, an electrode, a photoactive layer, a P-type conductive membrane, and an electrode. The P-type conductive membrane is a metal-oxide/carbon-nanotube composite membrane which is prepared by dispersing single-walled carbon nanotubes in an organic solvent, adding metal oxides to the mixed solution, dispersing the mixed solution to obtain a composite solution, and depositing the thus-obtained composite solution onto a substrate.
