Method for manufacturing nano-array electrode and photoelectric conversion device using same

Abstract

The present invention provides a method of manufacturing a nano-array electrode with a controlled nano-structure by filling an electrode material into the fine pores of an anodic-oxide porous alumina film obtained by anodically oxidizing aluminum in electrolyte, or by filling a material into the fine pores of an anodic-oxide porous alumina film obtained by anodically oxidizing aluminum in electrolyte and then filling an electrode material into the spaces defined by the nano-array formed by removing the anodic-oxide porous alumina film, or by filling repeatedly an electrode material in the fine pores of the anodic-oxide porous alumina film to fill a plurality of electrode materials. A high-performance, high-efficiency photoelectric converting device comprising a nano-array electrode manufactured by the method is also disclosed.
