Abstract
A color-mixing lens for use in a concentrator system and methods of manufacture and operation thereof. The color-mixing lens includes: (1) a light-transmissive substrate that receives broad spectrum light from a source, (2) a first plurality of prisms, located on the substrate, that refract and chromatically disperse the light received therein toward a first plurality of locations on an active region of a target cell, and (3) a second plurality of prisms located on the substrate that refract and chromatically disperse the light received therein toward a second plurality of locations on the active region. Relative dimensions of the first and second pluralities of prisms are preselected to cause the chromatically-dispersed light to mix and thereby increase a power output of the target cell by reducing inter-junction currents therein.
