  • Method for making ferroelectric material thin films
    Patent number: 10749056
    Abstract: A method of growing a FE material thin film using physical vapor deposition by pulsed laser deposition or RF sputtering is disclosed. The method involves creating a target to be used for the pulsed laser deposition in order to create a KBNNO thin film. The resultant KBNNO thin film is able to be used in photovoltaic cells.

  • Ferroelectric Perovskite Oxide-Based Photovoltaic Materials
    Publication number: 20170330983
    Abstract: 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)O3-?. The ferroelectric perovskite composition may be represented by the formula: xBa(Ni,Nb)O3.(1-x)ABO3 or xBa(Ni,Nb)O3-?.(1-x)ABO3. A method of producing the ferroelectric perovskite composition in thin film form is also provided.
