Abstract
A cost-effective, lightweight and compact polymer solar concentrator for a CPV system based on an acylindrical lens array and a freeform waveguide was demonstrated. The optical silicone material and cyclic olefin copolymer were compared as the solar concentrator and both materials achieved ∼160x optical concentration ratio as well as ∼90% system optical efficiency. High optical efficiency and good tracking tolerance show the future viability of replacing a typical glass concentrator with a polymeric solar concentrator.
