Abstract
SnS is a promising material for solar cell absorber layer application due to its low cost, easy availability and less toxicity than other semiconductor material used for the same purpose. SnS thin films as an absorber layer for photovoltaic application are deposited using chemical bath deposition (CBD) having a thickness of 550 nm from a solution containing SnCl 2 .2H 2 O, TEA, TA and NH 3 OH NH 3 OH is used to control the pH of the solution which is maintained at 5. The surface morphology of the deposited film has been examined using X-Ray diffraction and scanning electron microscopy. The optical as well as electrical properties of deposited film have been characterized using UV-Vis spectrophotometer and hall effect measurement system respectively. Results show that films deposited in this process have amorphous crystal structure and have good adherence to the substrate. The bandgap obtained is 1.4eV which is very suitable for its use as absorber material for thin film solar cell.
