A PZT Based Capacitor for Direct Solar Energy Harvesting and Storing

In this paper, we present a Solar Energy harvesting and storing system. The solar energy is converted to electric charge by photosensitizing film and the charge generated is stored between the upper membrane and lower membrane of a capacitor. A PZT material based capacitor is used to retain the charge. The proposed system not only harvest energy from solar sources but also stores the charge both achieved within a single structure. The structure is CMOS compactable and requires a high-k dielectric material thin film deposition of PZT material.
