Figure 5. J-V curves of optimized DSCs based on a Dyesol-S film as the light scattering layer over a Dyesol-T under layer [Dyesol-T (12 μm)/Dyesol-S (4 μm)] and a HRT-1 film as the light scattering layer over a Dyesol-T under layer [Dyesol-T (12 μm)/HRT-1 (4 μm)] under AM 1.5 G one sun intensity.

Inset is a titled SEM cross-sectional image of Dyesol-T (12 μm)/HRT-1 (4 μm) on the fluorine-doped tin oxide (FTO) and its schematic illustration.
