Abstract

The fundamental development of Cu₂ZnSnS₄ (CZTS) thin films by non-vacuum, liquid-based techniques have been investigated. CZTS has a suitable optical band gap of ~1.5 eV and a large optical absorption coefficient of over 10⁴ cm^-1. CZTS polycrystalline thin films were prepared by a non-vacuum liquid-based coating method. Characterization and analysis of the thin films were performed using the JEOL 7600F scanning electron microscope (SEM) and the Panalytical X-ray diffractometer (XRD) to determine the crystal structure, orientation and crystallite size. Results show the formation of kesterite CZTS.
