Abstract
Semiconductor QDs has been intensively studied to their interesting characteristics both from the views of fundamental research and practical applications. Colloidal quantum dots are grown in solution from precursors. In comparison amongst the quantum dots (QDs) available in the literature, cadmium supplied quantum dots (CdS QDs) are more popular because of their high luminescence, good quantum yield, wide band gap. The most popular method of preparation is hot organometallic precursor route. In this paper, very low cost and efficient CdS-QD has been synthesized using chemical bath method. The prepared CdS QDs are characterized by UV–Vis absorption, photoluminescence (PL), XRD. A quantum dot sensitized solar cell (QDSSC) will be proposed using a synthesized CdS.
