dye-sensitized solar cells with nitrogen-doped carbon nanotubes

摘要

dye-sensitized solar cells with nitrogen-doped carbon nanotubes a dye-sensitized solar cell comprising a metal oxide electrode, a counter electrode that is bonded to the metal oxide electrode and an electrolyte disposed between the metal oxide electrode and the counter electrode, wherein the electrode comprises a dye metal oxide located therein and the electrolyte comprises an electrochemical redox pair. In addition, between the metal oxide electrode and against the electrode, nitrogen-doped carbon (n-cnt) nanotubes are arranged, which are in electrical contact with the counter electrode. The invention further relates to a method for obtaining electrical energy by dye-sensitized solar cells according to the invention and to the use of nitrogen-doped carbon nanotubes as a catalyst in the reaction of an electrochemical redox pair, in particular the pair redox i sym / i ~ 3 ~ sym.
