A Nontoxic and Low‐Cost Solution‐Processed CZTS Absorber Layer for Solar Photovoltaic Applications: Solvent Effects on the Physical Properties

Abstract

Thin Films of Copper Zinc Tin SulfideIn article number http://doi.wiley.com/10.1002/pssa.202100882, Ahmed El Hichou and co‐workers present thin films of copper zinc tin sulfide (CZTS) successfully deposited using the sol–gel spin‐coating technique without any sulfurization. The effect of the solvent type on the structural, morphological, elemental composition, optical, and electrical properties is investigated. All the observed characteristics and results obtained in this study support the usage of spin‐coated CZTS films as absorber layers in thin‐film solar cells.
