Abstract

Co-produced: using [Co(en)(3)](2+/3+) based-electrolytes in p-type dye-sensitized solar cells (p-DSCs) gives record energy conversion efficiencies of 1.3 % and open-circuit voltages up to 709 mV under simulated sun light. The increase in photovoltage is due to the more negative redox potential of [Co(en)(3)](2+/3+) compared to established mediators.
