MODELLING THE EFFECT OF DEVICE GEOMETRY ON CONCENTRATION RATIOS OF QUANTUM DOT SOLAR CONCENTRATORS

摘要

Quantum dot solar concentrators (QDSCs) are static, non-imaging 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.
