Modelling the Effect of Device Geometry on Concentration Ratios of Quantum Dot Solar Concentrators

Quantum dot solar concentrators (QDSCs) are static, nonimaging concentrators which concentrate both direct and diffuse light. Using Monte-Carlo ray-trace modelling, concentration ratios (C) were predicted for QDSCs of different 2-D geometries. The optimum shape and size were determined, for given system parameters, by calculating the relative cost per unit power output. Devices with different 3-D geometry were also compared. The thickness of the plate was varied and devices with tapered thickness were modelled to investigate the effect on C
