Wide acceptance angle, non-imaging, triple junction based, 10/spl times/ composite space concentrator

A novel, wide acceptance angle, nonimaging, 10/spl times/, all-composite space concentrator array has been developed and prototyped as a possible lower cost alternative to the very high efficiency, multijunction technology based, planar space arrays. This triple junction cell based, carbon composite, concentrator array can provide similar high performance, while, at the same time, offers cost and weight advantages. Unlike other concentrator arrays, the 10/spl times/ composite concentrator array features relatively relaxed tracking requirements, which simplifies overall system design.
