Abstract: The energy conversion performance, mechanical robustness, and cost associated with fabrication of a thermoelectric device may be improved by three-dimensional flexible thermoelectrics.

Abstract: Disclosed are nanostructured materials that reflect light in selected spectra incorporated in dark colored textiles or substrates. In one aspect, a light reflecting material includes a textile exhibiting a dark color and formed of a plurality of fibers, and nanostructures arranged on the fibers and formed of a plurality of nanoparticles, the nanostructures having a dimension size of substantially less than ½ of a visible light wavelength, in which the nanostructures reflect light from the textile or substrate in at least one of infrared, near-infrared, or red visible light spectra.

Abstract: Methods, systems, and devices are disclosed for fabricating and implementing optically absorbing coatings. In one aspect, an optically selective coating includes a substrate formed of a solar energy absorbing material, and a nanostructure material formed over the substrate as a coating capable of absorbing solar energy in a selected spectrum and reflecting the solar energy in another selected spectrum. A concentrating solar power (CSP) system includes heat transfer fluids (HTFs); thermal energy storage system (TES); and solar receivers in communication with HTFs and including a light absorbing coating layer based on cobalt oxide nanoparticles.
