Abstract

The relation between surface states (SS) and the current–potential (j–V) response is unravelled in an electrochemical way. The photocurrent is initiated at the potential where SS turn vacant, the slope of j–V curves depends on the density of SS. The distribution of SS impacts the profiles of j–V curves of a hematite photoanode.
