Modification in the Chemical Bath Deposition Apparatus, Growth and Characterization of Nanostructured SnS Thin Films for Photovoltaic Applications

In recent years, semiconducting chalcogenide thin films have found worldwide applications in various fields of science and technology [1]. Tin sulfide, SnS, is one of the IV-VI semiconductors which along with transparent and conductive tin oxide thin film find wide applications in optoelectronic devices, gas sensors, and window materials for heterojunction solar cells [2, 3]. It may exhibit the ptype or n-type conductivity. Chemical bath deposition method is presently attracting considerable attention for metal sulfide thin film preparation due to its simplicity, repeatability, controllability, and its potential for dictating desired chemical reaction conditions as it dose not require sophisticated instrumentation like vacuum system and other expensive equipments [4].
