All photoanodes i.e. without and ZnS-passivated SnO2 (SnO2-ZnS NCs) are characterized for their structure, morphology, optoelectrochemical properties. SnO2-ZnS NC-electrodes show appreciable DSSCs performance due to an enhanced dye loading capability, light scattering ability, and suppressed recombination rate. The optimized SnO2-(4L) ZnS NC-photoanode demonstrates 200% enhancement in the power conversion efficiency compared to SnO2 NC-based photoanode. This is due to prolonged transient photovoltage decay and higher charge recombination resistance with a minimized recombination rate of photoelectrons. Mott-Schottkymeasurementsconfirm a negative shift in the conduction band position of SnO2-(4L) ZnS NCs photoanode (0.41 V) compared to SnO2 NC-photoanode.
