A hydrophilic nitroxide radical molecule, 4-hydroxy-2,2,6,6- tetramethylpiperidinoxyl (TEMPOL), was immobilized in a Nafion layer yielding a redox-active modified electrode which enhanced the reduction peak current: The modified electrode and the TEMPOL aqueous electrolyte were applied in a dye-sensitized solar cell to achieve a 2.1% conversion efficiency.
