| Abstract: | We investigated the effect of single-step electrodeposition methods for the fabrication of CZTS thin films as solar cell absorber layer. For deposition of CZTS thin films, a potentiostatic method and a pulsed potential electrodeposition method were examined. Near stoichiometric CZTS thin films were prepared by potentiostatic deposition method. On the other hands, the samples deposited by pulsed potential method showed wire-like CZTS nanostructures. The nanowires were composed of the Cu and S element mainly and included Zn and Sn microelements. From these results, we realized that the electrodeposition methods strongly affect the structural and compositional characteristics of as-deposited CZTS thin films. |
