In photoelectrochemical (PEC) cells, water oxidation to O2, when coupled to CO2 reduction, typically requires a pair of light absorbers or an applied bias voltage. Now, a bias-free PEC cell with a single sunlight absorber drives simultaneous CO2 reduction to give formate, and the oxidation of an organic substrate in aqueous conditions.
