  • OPTOELECTRIC DEVICES FABRICATED WITH DEFECT TOLERANT SEMICONDUCTORS
    Publication number: 20160293858
    Abstract: Using fundamental electronic structure properties as an indicative of defect tolerance, a broad class of semiconductors containing partially oxidized cations can be identified, as well as several specific instances that can share these properties. These defect tolerant semiconductors can make a high-performance optoelectric device, for example, photovoltaic cells.
