We report an investigation on optical, ferroelectric, and photovoltaic properties of transparent Sn-doped In2O3 (ITO)/Pb(Zr-0.53,Ti-0.47)O-3 (PZT)/ITO thin film capacitors. The ferroelectric PZT sandwiched structures grown on glass substrates exhibit a transmittance of 65% in the visible light range. The current-voltage characteristics show that the transparent PZT capacitors possess a significant photovoltaic response under a light illumination. Moreover, the photovoltaic response can be well tuned by an external electrical field, which can be understood by considering the tunable depolarized field in the PZT capacitors.
