Title: Spectrally selective semiconductor dielectric photonic solar thermal absorber

Abstract

A solar thermal absorber including a spectrally selective filter comprising a stack of dielectric layers and one or more semiconductor absorber layers. The dielectric layers are transparent to infrared radiation and have a refractive index contrast, and the semiconductor absorber layers have a band gap, such that the semiconductor absorber layers absorb at least a portion of the solar spectrum and the stack reflects infrared radiation.
