Abstract

The two-stage line-to-point focus solar concentrator with tracking secondary optics is introduced. Its design aims to reduce the cost per m 2 of collecting aperture by maintaining a one-axis tracking trough as the primary concentrator, while allowing the thermodynamic limit of concentration in 2D of 215 × to be significantly surpassed by the implementation of a tracking secondary stage. The limits of overall geometric concentration are found to exceed 4000 × when hollow secondary concentrators are used, and 6000 × when the receiver is immersed in a dielectric material of refractive index n = 1.5 . Three exemplary collectors, with geometric concentrations in the range of 500 1500 × are explored and their geometric performance is ascertained by Monte Carlo ray-tracing. The proposed solar concentrator design is well-suited for large-scale applications with discrete, flat receivers requiring concentration ratios in the range 500 2000 × .
