Zusammenfassung:A light-guide solar concentrator that requires less precision to assemble and manufacture than some other two-layer solar concentrators has a light-condensing layer and an optical waveguide layer. The light-condensing layer includes a plurality of focusing elements for focusing incident sunlight and a plurality of corresponding collimating elements for collimating the light for output to the optical waveguide layer. The optical waveguide layer receives the collimated light and has a plurality of deflectors for redirecting the light for lateral transmission through the optical waveguide layer toward an exit surface. A secondary optic optically coupled to the exit surface can also be provided to redirect the light toward a light collection area where a solar energy collector can be placed to harvest the concentrated sunlight.
