Abstract
Sensitized-type solar cells based on TiO₂ photoanodes and CdS quantum dots (QDs) as sensitizers have been studied. CdS QDs are grown on TiO₂ films, utilizing one-step microwave assisted chemical bath deposition (MACBD) method. This method allows a facile and rapid deposition and integration between CdS QDs and TiO₂ films. The photovoltaic performances of the cells fabricated using CdS precursor solutions with different concentrations are investigated. The results show that the cell based on MACBD deposited TiO₂/CdS electrode achieves a maximum short circuit current density of 7.20 mAcm⁻² and power conversion efficiency of 1.18 % at one sun (AM 1.5G, 100 mW cm⁻²), which is comparable to the ones prepared using conventional techniques.
