Nanocrystalline Copper sulphide thin films evoked much attention due to their vast potential in various fields. The Cu₂S thin films have wide range of well perspective applications such as photovoltaic cells, tubular solar collector, automobile glazing , solar control coatings, dye-sensitized solar cells, gas sensors, Photodetectors, electroconductive electrode, microwave shielding coatings, super conductors, potential nanometer-scale switch. There are several techniques such as Spray pyrolysis [1], Reactive magnetron sputtering[2], Atomic layer deposition (ALD)[3], Activated reactive evaporation [4], Electrochemical methods [5], Chemical vapor deposition (CVD) [6], Chemical bath deposition (CBD)[7,8], Modified chemical deposition[9], Successive ionic layer adsorption and reaction (SILAR) [10], Microwave assisted chemcial bath deposition (MA-CBD)[11] have been used for the deposition of Copper sulphide thin films, among them M-CBD is simple, economic and convenient, for large area deposition.
In this paper we report the preparation of Copper sulphide thin films from alkaline bath and studies the structural, surface morphological, optical and electrical properties of the as deposited thin films.
