A Review on Transition from pristine copper sulphide to copper sulphide-reduced graphene oxide (CuS-rGO) nanocomposite in electrode materials

Abstract:

In this review, we provide an overview of the improvement in electrode materials of dye sensitized solar cells (DSSCs), quantum dot sensitized solar cells (QDSSCs) and supercapacitors (SCs) when replacing pristine CuS nanomaterials by its nanocomposites, copper sulphide-reduced graphene oxide (CuS-rGO). An in-situ preparation of the nanocomposite in which sulphur precursor solution is added to the solution containing copper precursor solution and graphene oxide solution is discussed. The role of rGO in improving the photovoltaic performance and charge storing capacity of CuS is investigated. This study is mainly dedicated towards modern synthesis techniques of CuS-rGO nanocomposites and their vast array of applications, and finally, illustration of the future prospect of the wonderful nanocomposite materials.
