DYE-SENSITIZED SOLAR CELL WITH NITROGEN-DOPED CARBON NANOTUBES

摘要

A dye-sensitized solar cell comprises a metal oxide electrode, a counter electrode which faces the metal oxide electrode and an electrolyte arranged between the metal oxide electrode and the counter electrode, wherein the metal oxide electrode comprises a dye located thereon and the electrolyte comprises an electrochemical redox pair. Furthermore, between the metal oxide electrode and the counter electrode, nitrogen-doped carbon nanotubes (N-CNTs) are arranged, which are in electrical contact with the counter electrode. The invention further relates to a method of obtaining electrical energy by means of dye-sensitized solar cells according to the invention and to the use of nitrogen-doped carbon nanotubes as catalyst in the reaction of an electrochemical redox pair, in particular of the redox pair I⁻/I₃⁻.
