Ferroelectric Perovskite Oxide-Based Photovoltaic Materials

摘要

A ferroelectric perovskite composition, comprising a perovskite oxide ABO₃, and a doping agent selected from perovskites of Ba(Ni,Nb)O₃ and Ba(Ni,Nb)O_3-δ. The ferroelectric perovskite composition may be represented by the formula: xBa(Ni,Nb)O₃.(1-x)ABO₃ or xBa(Ni,Nb)O_3-δ.(1-x)ABO_3. A method of producing the ferroelectric perovskite composition in thin film form is also provided.
