Abstract
A method and device for harvesting and storing solar energy is provided. The device converts solar energy to electrical energy via the photovoltaic effect. The device includes a pair of electrodes, at least one of which is transparent to allow solar energy to pass through. A medium is disposed between the electrodes which exhibits a combination of photovoltaic and ferroelectric properties. When solar energy passes through the transparent electrode and is received by the medium, electron-hole pairs establish a voltage potential between electrodes in the device via the photovoltaic effect. The voltage potential may be retained and the mobile charge may be stored in the absence of solar energy via the ferroelectric effect.
