Concentrator optics concentrate incident radiation onto thermal or photovoltaic receivers. We investigate and develop single stage and multistage concentrator designs based on reflective (e.g. parabolic mirrors, heliostats) or refractive optics (e.g. Fresnel lenses or dielectric secondary concentrators) for linear or spot focusing systems in low, medium and high concentration applications.
Applications are concentrating collectors for solar thermal power plants (CSP) and optical systems for concentrator photovoltaics (CPV). Further information can be found in our Center for Optics and Surface Science and in the Research Topic III-V and Concentrator Photovoltaics.
