Abstract
A luminescent solar radiation concentrator is disclosed. Incident radiation of flux .phi..sub.1, and wavelength .lambda..sub.1, impinges enclosure wall V.sub.1 having a double index of refraction n.sub.1, n.sub.2 (where n.sub.2 >n.sub.1) and then is absorbed by cascade fluorescent concentrator/converter CL, which isotropically re-emits fluorescent radiation at wavelength .lambda..sub.2 and flux .phi..sub.2 (where .lambda..sub.2 >.lambda..sub.1, and .phi..sub.2 >.phi..sub.1) which then is absorbed by a solar photovoltaic cell. The double index of refraction wall prevents escape of fluorescence radiation from the enclosure.
