Abstract
Ray-trace modelling has been used to investigate the performance of luminescent solar concentrator (LSC) plates containing high quantum yield (QY) NIR emitting quantum dots (qd). Optical efficiencies and spectrally enhanced concentration ratios are compared to those of LSC plates containing green and orange emitting qds. Concentration ratios 2-5 times higher are predicted with the NIR emitting qds, partly due to the broader absorption range but more significantly due to lower re-absorption losses. The performance of the NIR plate is found to be similar to that predicted for a plate containing a single red Coumarin dye. For each luminescent species, the predicted optical efficiencies are higher for diffuse incidence than for direct incidence, as a higher fraction of the diffuse incident spectrum is within the absorption range.
