DYE-SENSITIZED SOLAR CELL WITH NITROGEN-DOPED CARBON NANOTUBES

摘要

The cell has a mating electrode facing a metal oxide electrode. An electrolyte is arranged between the metal oxide electrode and the mating electrode. The metal oxide electrode comprises a dye. The electrolyte comprises an electrochemical redox couple i.e. redox couple iodide/triiodide. Nitrogen-doped carbon nanotubes are arranged between the metal oxide electrode and the mating electrode. The nanotubes are electrically contacted with the mating electrode. The mating electrode is free from metal such as cobalt, rhodium, iridium, nickel, palladium, platinum, copper, silver and gold. The nanotubes include pyridine, pyrrolic and quaternary nitrogen groups at a surface. The nanotubes are milled under ammonia, amine and nitrogen atmosphere. An independent claim is also included for a method for obtaining electrical energy by a dye-sensitized solar cell.
