  7. Abstract:
  8. The Cu2ZnSnS4 (CZTS) quaternary compound, with suitable optical and electrical properties, is one of the most interesting materials for absorber layer of thin film solar cell. Since all constituents of CZTS, are abundant in earth’s crust and non-toxic, it is a proper replacement for the materials like CdTe and CuInSe2. The CZTS pellet was synthesized by the solid-state reaction and deposited on soda lime glass substrates by pulsed laser deposition (PLD) method. PLD technique has the advantages of offering stoichiometric preservation during the materials transformation from target to substrate and good crystallinity due to the highly energetic species. CZTS has was deposited in order to investigate the effect of substrate temperature on structure, composition and optical properties of these CZTS thin films. The results of characterization such as XRD,Raman, SEM, AFM, STS and UV/Vis demonstrated that in all films, CZTS has been grown with high purity and strong preferential orientation of grains along [1 1 2] direction and the grain sizes increased with increasing deposition temperature. The CZTS thin film which was deposited at 300 °C exhibited the best crystallinity, large particle-size and ideal energy band gap (~1.5 eV). In general, synthesizing and depositing CZTS with high purity and good crystallinity, and finding the optimal temperature for deposition by PLD method, are the results of this research
