Characterization of structure and growth of electrodeposited Cu-S ultra-thin films

Calchogenides such as CdSe and CdTe thin-films are well known semiconductors, used in manufacturing of last generation photovoltaic components. Toxicity and shortage of the involved elements must be considered in the advancement of technology. Hence scientific community is focusing attention on new compounds based on economic and low-environmental impact elements such as Cu, Sn, Fe and Zn. In particular, quaternary semiconducting materials based on the kesterite (Cu2ZnSnS4) mineral structure are the most promising candidates to overtake the current generation of light-absorbing materials for thin-film solar cells. Electrodeposition is known as a low-cost semiconductor growth technique for applications in electronic devices.
