concentrators. This rapid change is taking place in heavy mineral sand plants as a result of the improved efficiency of these new designs which make them unmatched in the field of gravity separation in the size range applicable. The changes in design which have allowed this increased efficiency and operator acceptance have been a steepening of the
Inefficient filters and overall efficiency are issues for display technology. Luminescent concentrator pixels have been used with CdSe/CdS quantum dot emitters, which enable both colour and ...
Light is absorbed by the coating and reemitted into waveguide modes for collection by the solar cells. We report single- and tandem-waveguide organic solar concentrators with quantum efficiencies exceeding 50% and projected power conversion efficiencies as high as 6.8%.
