this work involves the synthesis and the characterization of CZTS layers. The films were prepared on ITO/ glass substrate by one step electrodeposition technic without using the sulfurization step and compared with CZTS films prepared by sulfurization of electrodeposited Cu-Sn-Zn precursors. By adding Thiourea as a sulfur source and KSCN as a complexing agent, the electrodeposition process can give better results. Therefore, the effect of the sulfur source is investigated. The characterization of the absorber films was done by Cyclic Voltammetry (CV), ICP compositional analysis method, X-Ray Diffraction (XRD) and Scanning Electron Microscopy. The single step electrodeposition process is suggested to be better than the sulfurization and post-annealing treatment method.

Abstract
this work involves the synthesis and the characterization of CZTS layers. The films were prepared on ITO/ glass substrate by one step electrodeposition technic without using the sulfurization step and compared with CZTS films prepared by sulfurization of electrodeposited Cu-Sn-Zn precursors. By adding Thiourea as a sulfur source and KSCN as a complexing agent, the electrodeposition process can give better results. Therefore, the effect of the sulfur source is investigated. The characterization of the absorber films was done by Cyclic Voltammetry (CV), ICP compositional analysis method, X-Ray Diffraction (XRD) and Scanning Electron Microscopy. The single step electrodeposition process is suggested to be better than the sulfurization and post-annealing treatment method.
