• Study focuses on complexing agent free cathodic electrodeposition technique for developing ZnS as a buffer layer for CdS/CdTe based solar cells.

• Used sodium thiosulfate as the sulfur precursor for the first time in electrodepositing ZnS.

• Cleary illustrates the optimization of electrodeposition parameters, temperature, pH, deposition potential, and deposition time. 

• The optical absorption measurement revealed, low light absorbance by the materials while it has direct energy band gap of 3.64 eV, free of codeposited impurity species and shown a blue shift from bulk ZnS.

• Sodium thiosulfate has been effectively used to electrodeposit thin films of ZnS with ideal qualities of a buffer layer.
