Hydrocarbon selectivity in photoelectrochemical CO2 reduction has been limited due to a lack of low-overpotential catalysts and high-photovoltage semiconductors. Here Cu nanoflowers are interfaced with perovskite light absorbers for bias-free conversion of CO2 to ethane and ethylene coupled to water or glycerol oxidation.
