CuCrO₂ has been investigated as an alternative to conventionally used NiO in p-type dye sensitized solar cells (p-DSCs) using I^{鈥?/sup>/I₃鈥?/sup>- and [Co(en)₃]2+/3+-based redox mediators. The favorable valence band edge position of CuCrO₂ affords open circuit voltages as high as 734 mV when [Co(en)₃]2+/3+ is deployed as redox mediator. This is the highest reported open circuit voltage for any p-DSC to date, introducing mesoporous CuCrO₂ electrodes as a promising alternative to traditional NiO.}
