Experimental setup for measuring the photovoltaic performance of DSSCs. (a) Photograph of the DSSC, condenser lens-based solar concentrator system, and solar simulator, (b) schematic of light pathways in condenser lens-based solar concentrator system, and (c) SEM images of top view and side view of TiO2 NP-accumulated photoelectrode of the DSSC (Here, T25 single layer: 25-nm-sized TiO2 NP layer; T25/T240 double layer: 240-nm-sized TiO2 NP light-scattering layer applied on 25-nm-sized TiO2 NP layer).
