Spray CVD of copper indium disulfide films: Control of microstructure and crystallographic orientation

Communication: CnInS(2) is a good candidate material for high efficiency ab sorber layers in thin film solar cells. In this work, spray CVD is used for the first lime to deposit this promising material. Using a single-source p recursor, stoichiometric films with little carbon or phosphorus contaminati on are obtained, and although film microstructure and orientations are quit e sensitive to deposition parameters, such as substrate and flow rates, den se columnar growth and faceted crystalline features are produced.
