APPARATUS FOR CONVERTING LIGHT ENERGY INTO ELECTRIC ENERGY AND STORING IT

摘要

PURPOSE:To highly reliably convert light energy into electric energy of voltage ranging from 10V to several kV and efficiently store the energy. CONSTITUTION:An apparatus comprises a photoelectric converter 10 having an element 11 for generating electromotive force by light application and a storage device 30 for storing electric energy generated by the photoelectric converter 10, wherein the element 11 is made of a ferroelectric crystal such as BaTiO3 lead zirconate titanate (PLZT) having a bulk photovoltaic effect.
