The multiferroic Pb(Fe 1/2 V 1/2 )O 3 (PFV) bulk ceramic was fabricated by a conventional ceramic sintering method. The strong visible‐light photovoltaic effect in Sn‐doped‐In 2 O 3 (ITO)/PFV/ITO structure capacitor was observed. The open‐circuit voltage was up to ∼0.7 V, which was much higher than the value (∼0.3 V) in BiFeO 3 film. The photo‐excited electric current is almost proportional to the incident light illumination intensity. The good visible‐light photovoltaic makes PFV ceramic a potential candidate for practical application in solar cell devices.Visible‐light photovoltaic effect in multiferroic Pb(Fe 1/2 V 1/2 )O 3 bulk ceramics. The open‐circuit voltage and zero‐bias photocurrent are ∼0.7 V and 0.02 μA, respectively. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
