Abstract
An apparatus for converting light energy into electric energy and storing the same, which comprises a photoelectric conversion unit having an element that generates an electromotive force by irradiation of light and a unit for storing electric energy generated by the photoelectric conversion unit. The element comprises a ferroelectric crystal having a bulk photovoltaic effect such as BaTiO.sub.3, lead lanthanum zirconate titanate (PLZT) or the like. Light energy is converted into electric energy having a voltage ranging from 10 V to several kV with high reliability to be efficiently stored.
