Abstract
We report an investigation on optical, ferroelectric, and photovoltaic properties of transparent Sn-doped In 2O 3 (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.
