Two-stage 50X hybrid spectrum splitting CSP/CPV collector with InGaP/GaAs solar cells

Experimental performance of a two-stage 50X spectral beam splitting (SBS) parabolic trough collector (PTC) - incorporating double-junction epitaxial lift-off (ELO) InGaP/GaAs solar cells and using a suspended alumina particulate heat transfer media tested to 600°C - is presented.
