As the field of nonimaging optics has developed over the last 50 years, among its many applications, the best known and
recognized is probably in solar energy. In particular, the approach provides the formalism that allows the design of
devices that approach the maximum physically attainable geometric concentration for a given set of optical tolerances.
This means that it has the potential to revolutionize the design of solar concentrators. Much of the experimental
development and early testing of these concepts was carried out at the University of Chicago by Roland Winston and his
colleagues and students. In this presentation, some of many embodiments and variations of the basic Compound
Parabolic Concentrator that were developed and tested over a thirty-year period at Chicago are reviewed. Practical and
economic aspects of concentrator design for both thermal and photovoltaic applications are discussed. Examples
covering the whole range of concentrator applications from simple low-concentration non-tracking designs to ultrahigh-concentration
multistage configurations are covered.
