Abstract

Using the recently-invented Tailored Edge-Ray Concentrator (TERC) approach for the design of compact two-stage high-flux solar collectors - a focusing primary reflector and a non-imaging TERC secondary reflector - we present: (1) a new primary reflector shape based on the TERC approach and a secondary TERC tailored to its particular flux map, such that more compact concentrators emerge at flux concentration levels in excess of 90% of the thermodynamic limit; and (2) calculations and raytrace simulation results which demonstrate that V-cone approximations to a wide variety of TERCs attain the concentration of the TERC to within a few percent, and hence represent practical secondary concentrators that may be superior to corresponding Compound Parabolic Concentrator or trumpet secondaries.
