Strong visible-light photovoltaic effect in multiferroic Pb(Fe1/2V1/2)O3 bulk ceramics

Authors


Abstract

The multiferroic Pb(Fe1/2V1/2)O3 (PFV) bulk ceramic was fabricated by a conventional ceramic sintering method. The strong visible-light photovoltaic effect in Sn-doped-In2O3(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 BiFeO3 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.
