Development of CZTS thin films by non-vacuum, liquid-based techniques for efficient, low-cost CZTS solar cells

The fundamental development of Cu 2 ZnSnS 4 (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 10 4 cm -1 . CZTS polycrystalline thin films were prepared by a non-vacuum l...

Description
Summary:The fundamental development of Cu 2 ZnSnS 4 (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 10 4 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.
