| (a) Open circuit voltage ( V oc) decay rates of CdS QDSSCs based on both plains. The TiO2 NPs photoanode and RGO+TiO2 nanocomposite photoanode, (b) the energy level diagram of CdS QDSSC using the RGO+TiO2 photoanode, where the Fermi levels of TiO2, RGO, and redox (I−/I3−) are set to be at −4.21,[ 48 ] −4.42,[ 48 ] and −4.94 eV.[ 49 ] respectively, and (c) the variations of electron lifetime τ with voltage, obtained from Eq. ( 1 ) for six SILAR cycles |
