Stowable and deployable concentrator for solar cells

摘要

A stowable and deployable concentrator for solar cells, A flexible, springily resilient Fresnel lens is held in a frame whose relaxed condition holds the Fresnel lens as the linear fragment of a cylinder. When in this deployed shape, the Fresnel lens concentrates energy onto a strip of solar cells, The frame is springily mounted by support means, biased toward the deployed condition, and when the Fresnel lens and frame are pressed toward the cells, they tend to flatten toward a stowed condition.
