Abstract
Vertically aligned ZnO/CdTe/CdS nanocable arrays-on-ITO substrate were prepared as photoanodes for solar cells via successive ion adsorption and reaction of CdS on ZnO/CdTe nanocable arrays pre-synthesized by electrochemical deposition of CdTe on ZnO nanowire arrays. Dense ZnO/CdTe and CdTe/CdS interfaces were formed in ZnO/CdTe/CdS nanocables through transmission electron microscope analysis. Based on the photovoltaic properties, the thickness for both CdTe and CdS shells were optimized to ∼10 nm. Together with the high absorption over the visible light region and the good crystal quality as revealed, a photocurrent density of ∼12.4 mA/cm2 has been obtained for the ZnO/CdTe/CdS nanocable arrays photoanode under the irradiation of AM 1.5G simulated sunlight.
