The role of trapped radiation transport losses on the performance of dye doped PMMA planar luminscent solar concentrators has been studied. A simple method has been devised to separate experimentally transport losses from the initial conversion losses in the collector, and it was shown that transport losses presently prevent luminscent solar concentrators from achieving useful intensity concentrations. An experimental and theoretical study of individual transport losses showed that matrix absorption and scattering and imperfect total internal reflection are the dominant transport losses at present. It was concluded that intensity concentrations of 100 for AM1 solar radiation should be possible in the near future and that the theoretical limit on intensity concentration was~1000.
