Abstract
We report a large photovoltaic (PV) effect in multiferroic Bi2 FeCrO6 (BFCO) films under monochromatic illumination at 635 nm with an intensity of 1.5 mW cm-2. These multiferroic films exhibit a large photocurrent at zero bias voltage and an open-circuit voltage of about 0.6 V. A high PV power conversion efficiency of about 6% for red light is achieved and attributed to a high degree of B-site cationic ordering between Fe and Cr sublattices, the tuning of which is likely to play a key role in further improvements of the PV properties in BFCO.
