Planar concentrators near the ├ętendue limit. Academic Article uri icon


  • Recently proposed aplanatic imaging designs are integrally combined with nonimaging flux boosters to produce an ultracompact planar glass-filled concentrator that performs near the etendue limit. Such optical devices are attractive for high-efficiency multijunction photovoltaics at high flux, with realistic power generation of 1 W from a 1?mm2 cell. When deployed in reverse, our designs provide collimation even for high-numerical-aperture light sources.
