Abstract

In this work, a novel process to fabricate copper zinc tin sulfide (Cu₂ZnSnS₄, CZTS) thin films under non-vacuum system was reported. CZTS thin film was prepared successfully by sulfurizing stacked CZT sol-gel layers and thioacetamide (C₂H₅NS, TAA) layers. The thin films presenting different characteristics due to different copper sources were observed. The X-ray diffraction (XRD) and Raman shift peaks showed that copper from copper (II) acetate (CuOAc) attributed to CZTS while copper from copper (II) chloride attributed to Cu₂S. Field emission scanning electron microscopy also showed different morphologies.
