Abstract:
A concentrating solar energy receiver, comprising:a primary parabolic reflector having a principal axis and a center and a high reflectivity surface on a concave side of said reflector and having a focal axis extending from said center of said concave side of said reflector and passing through a focal point of said primary parabolic reflector, said high reflectivity surface having a restricted reflectivity over frequency such that light at wavelengths less than a minimum wavelength and greater than a maximum wavelength is attenuated to reflect light over a selected portion of the solar energy spectrum; and a conversion module having a reception surface wherein said reception surface is spaced from said focal point by a distance and disposed to receive a cross-section of radiant solar energy at the restricted reflectivity reflected from said concave side of said primary parabolic reflector such that said conversion module is only subjected to such restricted reflectivity said frequency.
