摘要: We exploited alternated electrodeposition of Cu, Sn and S to obtain CuxSnySz thin films. These materials are kesterite-type chalcogenides that have attracted a relevant interest from worldwide researchers as low cost high conversion efficiency solar cell devices. Films were grown on silver substrate, controlling the growth electrodeposited structures at nanometric level. The obtained films characterized by diffuse reflectance spectroscopy, voltammetric stripping atomic force microscopy. Experimental bandgap energies resulted linearly modulated changes chemical composition thickness. On basis these results, we candidate room temperature method for technology with energy investment negligible environmental impact. Copyright © 2013 John Wiley & Sons, Ltd.
