[en] Solar concentrators made of a single refractive primary optics are limited to a concentration ratio of about 1000× [Opt. Express19, A280 (2011)OPEXFF1094-408710.1364/OE.19.00A280], due only to longitudinal chromatic aberration, while mirrors are limited to ∼46,000× by the angular size of the Sun. To reduce the chromatic aberration while keeping cost-effective systems for concentrated photovoltaics, a study of four different kinds of flat Fresnel doublets made of polycarbonates and polymethyl methacrylate is presented. It reveals that Fresnel doublets may have fewer optical losses than non-Fresnel doublets, with a lower lateral chromatic split allowing for even higher concentration ratio.
