  • METAL-OXIDE/CARBON-NANOTUBE COMPOSITE MEMBRANE TO BE USED AS A P-TYPE CONDUCTIVE MEMBRANE FOR AN ORGANIC SOLAR CELL, METHOD FOR PREPARING SAME, AND ORGANIC SOLAR CELL HAVING IMPROVED PHOTOVOLTAIC CONVERSION EFFICIENCY USING SAME
    Publication number: 20120255616
    Abstract: 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.
