Stacked SnS/Cu layers byCBD were used to fabricate CTS solar cells.
Monoclinic CTS thin film with Cu/Sn=1.68 was demonstrated in this study.
Mo/SnS/Cu stacked order of layers was found to produce most efficient solar cell.
Up to 1% efficient CTS solar cells were obtained with high Jsc of 19.2 mA cm−2.
