Deposition of Cu₂ZnSnS₄ Thin Film by Pulsed Laser Deposition and Assembly of Thin Film Solar Cell with the Novel Structure of FTO/CdS/Cu₂ZnSnS₄/Mo

Abstract:

Cu₂ZnSnS₄ (CZTS) thin film was successfully prepared by pulsed laser deposition using CZTS nanocrystal as a source and the thin film solar cell with the novel structure of FTO/CdS/CZTS/Mo was assembled. At the laser incident energy of 6 J·cm^-2, the chemical composition of the CZTS thin film was Cu_1.74Zn_0.80Sn_1.00S_4.04, near to stoichiometric ratio. The thin film solar cell with the novel structure of FTO/CdS/CZTS/Mo gave short circuit photocurrent density of 1.01 mA·cm^-2, open circuit voltage of 0.39 V, and fill factor of 0.485, corresponding to the photoelectric conversion efficiency of 0.19% at the illumination (Air Mass 1.5, 100 mW·cm^-2).
