ABSTRACT

Investigation in photovoltaic studies are more focusing on finding new absorber materials for replacing caldmium (Cd), arsenic (As), etc. In this direction, tin (II) sulfide (SnS) based materials has caught many researcher attention as a potential absorber layer. However, with its high resistivity and low conductivity researchers has shown that introducing dopant material to SnS, it is considered as the best option. In that regards, cobalt doping concentration and chemical bathed thin film samples are produced for this study.

For the deposition of the Cobalt doping Tin Sulfide, 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 cobalt is modified.
