|Abstract:||We report photovoltaic (PV) effect in multiferroic Bi0.9Sm0.1Fe0.95Co0.05O3 (BSFCO) thin films. Transition metal modified polycrystalline BiFeO3 (BFO) thin films have been deposited on Pt/TiO2/SiO2/Si substrate successfully through pulsed laser deposition (PLD). PV response is observed under illumination both in sandwich and lateral electrode configurations. The open-circuit voltage (V-oc) and the short-circuit current density (J(sc)) of the films in sandwich electrode configuration under illumination are measured to be 0.9 V and -0.051 mu A cm(-2). Additionally, we report piezoresponse for BSFCO films, which confirms ferroelectric piezoelectric behaviour.|
