Charge-recombination at the NiO/electrolyte interface is one of the performance-limiting factors that prevent dye-sensitized p-type solar cells (p-DSCs) from matching the efficiency of conventional TiO2 devices. This article describes a photoelectrochemical investigation of the charge-transfer processes at the NiO/electrolyte interface. NiO appears to catalyze the oxidation iodide but the addition of GuSCN inhibits recombination. These results suggest that new redox electrolytes will be needed if Tandem DSCs are to exceed the efficiency of state-of-the-art TiO2 devices.
