Figure 5From: Facile solution growth of vertically aligned ZnO nanorods sensitized with aqueous CdS and CdSe quantum dots for photovoltaic applications J-V characteristics of different QDSC. ZnO nanorods (curve 1: filled circle), ZnO nanorods decorated with CdS QDs (curve 2: open circle), ZnO nanorods decorated with CdSe QDs (curve 3: filled triangle), ZnO nanorods decorated with both CdS and CdSe QDs (curve 4: open triangle), ZnO nanorods coated with Al2O3 and then decorated with CdSe QDs (curve 5: filled square), and ZnO nanorods in situ grown in a solution containing CdSe QDs (curve 6: open square).Back to article page
