  • Cupric oxide semiconductors
    Patent number: 10115847
    Abstract: A method of preparing a cupric oxide semiconductor. The method includes providing a substrate having a first surface, forming a cuprous oxide layer on the first surface, converting the cuprous oxide layer into a cupric oxide layer via an oxidation reaction, and depositing additional cupric oxide on the cupric oxide layer, which serves as a seed layer, to yield a cupric oxide film, thereby obtaining a cupric oxide semiconductor. Also disclosed are a cupric oxide semiconductor thus prepared and a photovoltaic device including it.
    Type: Grant
    Filed: April 2, 2015
    Date of Patent: October 30, 2018
    Assignee: Trustees of Tufts College
    Inventors: Changqiong Zhu, Matthew Panzer
