The objective of my research is mainly focused on the development of series of inorganic colloidal semiconductor nanocrystals (II-VI, Cu2ZnSn(SxSe1-x)4, CuInGa(S/Se)2, Cu2Zn(Ge1-xSnx )(SySe1-y)4 and its metal semiconductor heterojunction .I am also interested in the development of novel synthesis strategies to control the shape, composition and crystal structure of these multicomponent nanocrystal. A key feature of my research is to develop assembly approaches to assemble particularly anisotropic structure (Nanorod) of these functional nanocrystals into high density 1D, 2D and 3D superlattice structures using various Self-assembly techniques such as drop casting, controlled solvent evaporation under an electric field, and electrophoresis. I am also looking on the possibilities of integrating these assembled nanocrystal architectures in low cost application such as solution processed solar cells.
