Abstract:
In this study, CdSe quantum dots (QDs) were prepared using colloidal trioctylphosphine (TOP) with an organic ligand layer and oleic acid as a capping agent, and a photoelectrode anode was prepared using CdS/CdSe QDs/ZnS thin film deposition on a TiO 2 electrode via the successive ionic layer adsorption and reaction (SILAR) method. The results indicated that the short current density increased from 4.79 mA/cm 2 to 13.97 mA/cm 2 because the conduction band of the CdSe (size ∼ 3 nm) QDs became higher than that of both TiO 2 and CdS. As a result, the stimulated electrons were efficiently injected into the conduction band of TiO 2 and CdS. In addition, the dynamic resistance and the lifetime of stimulated electrons in the QDSSCs were investigated using Nyquist and Bode plots. © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1774–1779, 2015
