A changeable critical state for a switchable photocurrent direction via the photo-electrochemical photocurrent polarity switching effect in BiFeO 3 nanoparticulate films

A PEC system utilizing BiFeO 3 nanoparticulate films, exhibiting tunable photocurrent reversal controlled by electrolyte composition is reported. The system's behavior, predicted by the Nernst equation, provides valuable insights for PEC-catalysis.
