Identifying loss mechanisms and predicting device performance are key goals of device and process characterization. Photoconductance measurements allow the extraction of the Implied Voc and Suns Voc, which together can be used for process monitoring, for loss analysis and to identify the potential device performance in the absence of unwanted defects. In this paper, we measure the Implied Voc a...

An innovative concept for fabricating solar trough concentrators based on pneumatic polymer mirrors supported on precast concrete frames is presented. Optical aberration is corrected by means of a secondary specular reflector in tandem with the primary cylindrical concentrator. The optimal design is formulated for maximum solar flux concentration. The Monte Carlo ray-tracing technique is applie...

This article investigates the discrepancy between theoretical and experimental optical characterisation results of a Fresnel Lens - silicon on glass (SOG), as primary component toward UHCPV >3000 suns design (Shanks et al., 2018). All equations were elaborated for single- multi-junction solar cells, emphasising performance when focal spot area is larger or lesser than cell area. simple predicti...
