Recently, the anomalous photovoltaic (PV) effect in BiFeO 3 (BFO) thin films, which resulted in open circuit voltages (V oc) considerably larger than the band gap of the material, has generated a revival of the entire field of photoferroelectrics. Here, via temperature-dependent PV studies, we prove that the bulk photovoltaic (BPV) effect, which has been(More)
