A dye-sensitized solar cell comprises a metal oxide electrode, a mating electrode which faces the metal oxide electrode, and an electrolyte which is arranged between the metal oxide electrode and the mating electrode, wherein the metal oxide electrode comprises a dye which is located on it and the electrolyte comprises an electrochemical redox couple. Furthermore, nitrogen-doped carbon nanotubes (N-CNT) are arranged between the metal oxide electrode and the mating electrode and the mating electrode makes electrical contact with said nitrogen-doped carbon nanotubes. The invention also relates to a method for obtaining electrical energy by means of dye-sensitized solar cells according to the invention, and to the use of nitrogen-doped carbon nanotubes as catalysts in the reaction of an electrochemical redox couple, in particular the redox couple l |
