Gathering information on the atomic nature of reactive sites and trap states is key to fine tuning catalysis and suppressing deleterious surface voltage losses in photoelectrochemical technologies. Here, spectroelectrochemical and computational methods were combined to investigate a model photocathode from the promising chalcopyrite family: CuIn<sub>0.3</sub> Ga<sub>0.7</sub> S<sub>2</sub> . We found that voltage losses are linked to traps induced by surface Ga and In vacancies, whereas operando ...[more]
