  • Patent number: 10288323
    Abstract: A metamaterials-enhanced solar receiver for a Concentrating Solar Power (CSP) plant includes spectrally-selective metamaterials-enhanced surface features engineered into the sunlight-receiving (upward-facing) surface of a high melting point sunlight absorbing material. The spectrally-selective features include substantially cube-shaped microcavities surrounded by associated interlaced walls disposed in a periodic (waffle-like) array having a grating period in the range of 0.5 to 2 microns, thereby forming a metamaterial structure exhibiting high absorptance efficiency (i.e., above 95%) of incident solar radiation having wavelengths in the visible light spectrum through induced coupling of visible light to the interlaced walls by way of generating surface plasmonic waves that resonate at visible light frequencies, whereby thermal energy is efficiently absorbed into the solar receiver to heat a transfer fluid.

  • Patent number: 10190805
    Abstract: A solar collector housing that is opened and closed without tools includes structure for accommodating temperature-related expansion and contraction of a polymer absorber housed within the collector. The housing includes a transparent cover, a frame for holding the transparent cover, and a base. The cover, frame and base collectively define a hollow interior within which the polymer absorber is positioned. A plurality of latches is secured to an exterior of the frame. The frame and base are pivotally connected to one another when the latches are open so that the collector housing can be opened. The housing cannot be opened when the latches are closed. A pair of variable gate closure components are positioned in slots formed in a second end of the collector and enable the polymer absorber to expand and contract without placing stress on the absorber tubes.
