Abstract:

Recent progress in passive radiative cooling technologies have significantly improved cooling performance under direct sunlight. Performance of existing passive radiative coolers for air conditioning and portable refrigeration applications can be improved with a material that is solar reflective and infrared transparent that can also have a low thermal conductivity.

Abstract:

A silica aerogel having a mean pore size less than 5 nm with a standard deviation of 3 nm. The silica aerogel may have greater than 95% solar-weighted transmittance at a thickness of 8 mm for wavelengths in the range of 250 nm to 2500 nm, and a 400 C. black-body weighted specific extinction coefficient of greater than 8 m/kg for wavelengths of 1.5 μm to 15 μm. Silica aerogel synthesis methods are described. A solar thermal aerogel receiver (STAR) may include an opaque frame defining an opening, an aerogel layer disposed in the opaque frame, with at least a portion of the aerogel layer being proximate the opening, and a heat transfer fluid pipe in thermal contact with and proximate the aerogel layer. A concentrating solar energy system may include a STAR and at least one reflector to direct sunlight to an opening in the STAR.
