Abstract
- In this report, a novel and facile in situ gas-solid reaction method has been developed for the deposition of CdS quantum-dots (QDs) on a mesoscopic TiO film. In the approach, cadmium nitrate solution was first coated on mesoporous TiO films, and subsequently transformed into CdS QDs (with size about 2-3 nm) by reaction with hydrogen sulfide (HS) gas generated in a closed container at room temperature. Different from the conventional solution techniques, this method offers new opportunities for rapid and facile deposition of CdS QD-coated TiO films without the introduction of the by-products. With the CdS QDs-decorated TiO active electrodes, the liquid and solid solar cells were fabricated with power conversion efficiencies ( PCEs) of 1.90 and 0.80%, respectively. [ABSTRACT FROM AUTHOR]
