Photovoltaic solar concentrator design uses Spherical Gradient Index (GRIN) lens to achieve efficient and simple solar power conversion

Summary

Vijay Modi, Ph.D.

Technology Benefits

Spherical Gradient Index (GRIN) lens achieves efficient focusing of sunlight without moving.Unique refractive properties allow perfect focusing over the very wide field of view of the lens (360 degrees). The mechanical systems are optimized and simplified; the self-contained photovoltaic solar concentrator does not contain any external moving parts.Various refractive index profiles allows GRIN lens to be manufactured by currently available materials and fabrication techniques. Patent information:Patent Published (WO/2012/033840)
