Abstract

In this work, we conducted the photovoltaic based on a set of CdS/CdSe/ZnS photo anodes by using successive ionic layer adsorption and reaction (SILAR) processes. The results show that the open circuit increased from 0.29 V to 0.79 V because the excited electrons were efficiently generated in the conduction band of quantum dots when the number SILAR changed. Furthermore, the effect of SILAR cycles on the recombination resistance was discussed to base on the electrochemical impedance spectroscopy results.

Key Words   
Quantum dots, Solar cells, SILAR.
