摘要：The HCPV industry has converged on the use of relatively inexpensive Fresnelrefractive optics to concentrate sunlight to 500-1000 suns or more. One fundamentaldisadvantage of using Fresnel optics is their susceptibility to chromatic aberration. With aFresnel lens, this chromatic aberration increases as a function of distance away from the
optical axis of a lens—that is, greater chromatic aberration is seen as one moves along aradius away from the center of a Fresnel lens. Embodiments herein disclose TIR-mediatedoptics which can be used alone or with Fresnel-mediated optics to concentrate solarenergy. The system and method described herein utilize novel TIR and Fresnelconcentrator designs to enable lower F-number optical systems, resulting in smallersystems with higher concentrations of solar energy than is currently attainable withFresnel lenses alone (or with secondary optics) while simultaneously minimizingchromatic aberration.
