METHOD OF FORMING METAL OXIDE NANOTUBE AND THE DYE-SENSITIZED SOLAR CELL USING THE METAL OXIDE NANOTUBE

摘要

PURPOSE: A forming method of metal oxide nanotube is provided to include metal nanoparticles causing the plasmon phenomenon in the inner wall of the metal oxide nanotube, thereby increasing the light efficiency of dye-sensitized solar cell. CONSTITUTION: A forming method of metal oxide nanotube comprises following steps. A polymeric fiber including metal nanoparticles is formed. A metal oxide thin film is formed on the surface of the polymeric fiber by depositing metal oxide. The metal oxide nanotube including the metal nanoparticles on the inner wall is formed by removing the polymeric fiber. The polymeric fiber is formed by spinning the solution in which the metal nanoparticles and the polymer are mixed. The metal nanoparticles are able to cause the plasmon phenomenon. The metal oxide thin film is formed with atomic layer deposition method. The thickness of the metal oxide thin film is 50-150Å.
