Abstract
Spherical gradient index (GRIN) lens that can achieve perfect imaging and maximum concentration is provided. Various refractive index profiles for the GRIN lens allow the lens to be manufactured by the currently available materials and fabrication techniques. Systems and methods for photovoltaic solar concentration are provided in which the optic tracks the sun and the photovoltaic cell remains stationary. The optic of such systems and methods can include perfect imaging spherical GRIN lens to provide high flux concentration.
