  • SOLAR THERMAL RECEIVERS WITH MULTI-SCALE LIGHT TRAPPING GEOMETRY AND FEATURES
    Publication number: 20210254861
    Abstract: Solar receivers including a plurality of multi-scale solar absorbing surfaces arranged such that light or heat reflected from or emitted from one or more of the plurality of solar absorbing surfaces impinges one or more other solar absorbing surfaces of the solar receiver. The disclosed receivers increase the amount of absorbed energy from a concentrated light source, such as a heliostat field, and reduce radiative and convective heat losses.
    Type: Application
    Filed: February 2, 2021
    Publication date: August 19, 2021

  • Bladed solar thermal receivers for concentrating solar power
    Patent number: 11015838
    Abstract: A bladed solar thermal receiver for absorbing concentrated sunlight is disclosed. The receiver includes a plurality of panels arranged in a bladed configuration for absorbing sunlight. The bladed configurations can be radial or planar. The receiver design increases the effective solar absorptance and efficiency by providing a light trap for the incident solar radiation while reducing heat losses from radiation and convection.
    Type: Grant
