A polycrystalline BiFeO3 film on Pt/Ti/SiO2/Si was fabricated using the spin coating technique.
The film shows diode-like characteristics with and without poling measured under dark conditions.
However, it exhibits a switchable photovoltaic effect with light illumination under poled condi-
tions. The measured photovoltaic effect revealed an open circuit voltage of $0.47 V and a short cir-
cuit current of 3.82 lA/cm 2 under the illumination of 165 mW/cm 2 irradiance. The studies clarified
the dominant role of the depolarization field rather than the interface in the photovoltaic character-
istics of the BiFeO 3 film. Significantly, the photo-capacitance effect was demonstrated with a sub-
stantial enhancement in capacitance ($45%) in Au/BiFeO3 /Pt geometry, which could open up a
new window for BiFeO 3 applications.
