In this work, we report some preliminary results concerning the fabrication of quaternary semiconductor Cu2ZnSnS4 (CZTS) thin films on a flexible substrate through the simultaneous electrodeposition of elements having different standard electrochemical potentials. CZTS thin films were obtained by potentiostatic deposition from aqueous baths at room temperatureand under N2 atmosphere, varying bath composition. Chemical composition and structure of the electrodeposited films were evaluated by EDS, SEM and XRD. Preliminary results on the photoelectrochemical behaviour of the films will be also presented. We obtain CdTe thin films with good physical properties, these samples can be used as window material in CdTe/CZTS solar cells to improve the photovoltaic efficiency
