Bismuth ferrite (BFO) is perhaps the only material that is multiferroic (ferroelectric, antiferromagnetic) at room temperature. In this review, its use in photovoltaic applications has been investigated. A low band gap (Eg ~ 2.2-2.7 eV) within the visible light range makes BFO a potential candidate for such application. We review recent progress in the observance of photovoltaic effect in BFO addressing the role of heterostructures, effect of doping and the role of domain and electrode in the photoresponse of BFO. Recent studies reveal the perovskite ferroelectrics are the promising materials for photovoltaic application. In the last few years, a considerable rise has been witnessed in the study of ferroelectric thin films. This can be attributed to the high open circuit voltages in these thin films. It has been observed that the physical mechanism of photovoltaic effect in ferroelectrics is still under observation /advancement as compared to the semiconductor conventional photovoltaic.
