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)
- Technology Application
- Photovoltaic solar concentrators, enabling very high concentration with only one optical element; Applications include rooftop solar panels and use in solar farmsFocusing light on an optical fiber and delivering natural light for indoor applicationsGRIN lens for photography and infrared imagingRadiation concentration
