Abstract

Cadmium sulfide (CdS)-sensitized solar cells have been investigated. Chemical bath deposition (CBD) based on an aqueous medium involving cadmium acetate, thiourea, ammonium acetate and ammonia was utilized to assemble CdS quantum dots (QDs) onto mesoporous TiO2 films for dye-sensitized solar cell (DSC) applications. Physical and chemical properties of the formed TiO2/CdS bilayers were analyzed using field emission scanning electron microscope (FE-SEM), Raman spectroscope, ultraviolet-visible light (UV-VIS) spectrometer and X-ray diffraction (XRD). An efficiency as high as 1.50% for the CdS Q dots-sensitized DSC was achieved using the present method. The results have demonstrated the potential applications of CBD CdS Q dots for sensitized solar cells.
