  • Spectrally selective semiconductor dielectric photonic solar thermal absorber
    Patent number: 10215447
    Abstract: A solar thermal absorber including a spectrally selective filter comprising a stack of dielectric layers and one or more semiconductor absorber layers. The dielectric layers are transparent to infrared radiation and have a refractive index contrast, and the semiconductor absorber layers have a band gap, such that the semiconductor absorber layers absorb at least a portion of the solar spectrum and the stack reflects infrared radiation.
    Type: Grant
    Filed: April 29, 2016
    Date of Patent: February 26, 2019
    Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGY
    Inventors: Nathan H. Thomas, Austin Minnich
