Structures and electronic properties of SnS quantum dots (QDs) are studied by using first principles density functional theory (DFT) for their potential applications in the design of environmentally friendly green solar cells. QDs of different sizes are investigated and effect of ligation on geometry optimization and the electronic properties of the QDs are investigated. Also, effect of stoichiometry of the QDs is also investigated. There is a red shift on the absorption peak of the QDs as the size of QDs is increased.

Keywords: Quantum dots, solar cells, DFT.
