ABSTRACT

Investigation in photovoltaic studies are more focusing on finding new absorber materials for replacing cadmium (Cd), arsenic (As), etc. In this direction, tin (ІІ) sulfide (SnS) based material has caught many researcher attention as a potential absorber layer. However, with its high resistivity and low conductivity researches has shown that introducing dopant materials to SnS, it is considered as the best option. In that regards, Aluminium doping concentration and chemical bathed thin film samples are produced for this study. For the deposition of Aluminium doped Tin Sulphide, Chemical bath deposition techniques is used in this study to produce the films. Overall, the results shows that the optical properties of SnS doped with Aluminium is modified.
