Better out than in

Single junction GaAs solar cells with conversion efficiencies above 28% have been reported. Perhaps counter-intuitively, these new designs specifically allow photons to be emitted. The group claims that by letting the internally generated luminescence photons to efficiently exit the device rather than be reabsorbed, increases the voltage created and thus the cell efficiency. Full results will be presented at CLEO 2012.
