“…Electrochemical studies in CIGS electrodeposition, generally, use an electrochemical cell with electrodes suspended vertically. However, an electrochemical cell with electrodes in a horizontal position has advantages over a cell with vertical electrodes, principally because the ion transport mechanism as well as the natural flow by convection allows a better uniformity on the WE surface; in this way, the composition is homogeneous through the film [31].…”

“…In previous studies, it has been shown that in the CIGS film synthesized by electrodeposition, the composition is related to the current density; if the current density is high, the CIGS film composition is copper-poor. On the other hand, if the current density is low, the CIGS film composition is copper-rich [31]. Therefore, the CIGS film has a composition that varies according to the contour line; the zones with a dark color are cooper-poor while the zones with a light gray color are copper-rich.…”

Applying mechanical perturbations at the working electrode during the electrodeposition process is a novel strategy for materials synthesis that has been used for Cu(In,Ga) Se 2 (CIGS) thin film synthesis. A mechanical perturbations strategy was applied during one-step electrodeposition, and the results are compared with the traditional one-step electrodeposition where no mechanical perturbations were applied. In both cases, a potentiostatic mode was employed, where DC potential is applied to the working electrode with respect to the reference electrode; the potential is regulated by the current at an auxiliary electrode. The CIGS films obtained from both strategies were analyzed as electrodeposited and after being annealed in a selenium atmosphere. The annealed film morphology obtained with the potentiostatic mode plus periodical mechanical perturbations was denser and more compact than the film without mechanical perturbations. Using contour lines, the morphology evolution and mass transport distribution on the working electrode during the electrodeposition process are explained.
