• those reported for the individual dye molecules within the nanoparticles (60 and 930 GM, respectively) [11]. The comparison leads to α ≈ 3.4 and α ≈ 2.9, which are values compatible with the expected refractive index from the dye aggregates [34][35] (see Experimental section). Bleaching of nanoparticles

• ZnO could be a preferential alternative to TiO2. However, ZnO suffers from lack of stability in the acidic Ru-based sensitizers in DSSCs, leading to the formation ZnO/dye aggregates [30]. This can be easily avoided for QDSSCs where the used sensitizer, CdS, is neutral in nature. In our earlier work
