摘要

Several works have appeared in the literature as a result of the joint activity of Imperial College London with the European Solar Test Installation and other European research centres on luminescent solar concentrators: some have been specifically related to indoor and outdoor characterisation. Within the characterisation processes, the external quantum efficiency is particularly important: by means of external quantum efficiency measurements, spectral mismatch correction can be performed, enabling performance predictions for any given irradiance conditions. In recent works an increase in module efficiency due to a diffusive reflector at the backside of the concentrator has been shown. In this work we present recent results on the impact of a non-index-matched backside diffusive reflector on the external quantum efficiency of a luminescent solar concentrator and therefore on the short-circuit current of the device: the result is particularly relevant in view of using luminescent solar concentrators in building integration of photovoltaics.
