Realizable planar gradient-index solar lenses
Mechanical Engineering Department, Columbia University, New York, New York 10027, USA.Optics Letters (Impact Factor: 3.29). 04/2012; 37(7):1235-7. DOI: 10.1364/OL.37.001235
The design of single element planar hemispherical gradient-index solar lenses that can accommodate the constraints of realistic materials and fabrication techniques are presented, and simulated with an extended and polychromatic solar source for concentrator photovoltaics at flux concentration values exceeding 1000 suns. The planar hemispherical far-field lens is created from a near-field unit magnification spherical gradient-index design, and illustrated with an f/1.40 square solar lens that allows lossless packing within a concentrator module.
