Paper Abstract

An optical sub-system design for a solar concentrator having applications to high temperatures thermal photovoltaic concepts has been developed. The baseline system consists of a spherically segmented primary mirror optically coupled to a compound parabolic concentrator and a hemispherical receiver. Secondary concentrators having conical, parabolic and hyperbolic cross sections are considered Parametrically. Performance trade-offs relative to, concentration ratio, system configuration and manufacturing sensitivities have been rigor-ously evaluated using geometric ray tracing techniques. The advantages of using a two stage concentrator over a single collecting aperture are discussed. Performance of typical systems are reviewed and cover transmission, flux distribution, and tolerance sensitivities.
