Abstract

In this works, we have prepared the quantum dots solar cells (QDSSCs) based on the TiO2/CdS/CdSe photoanodes coated by the ZnS layers for the reduced recombination and the increased performance efficiency in the QDSSCs. The results indicate that the highest performance efficiency obtained correspond to the photoanodes were coated with ZnS passivation. In addition, we also investigated the effect of the ZnS passivation coated on the recombination resistance, the chemical capacitance of the performance QDSSCs through the electrochemical impedence spectroscopy (EIS).
