Preparation of Cu₂ZnSnS₄ Film by Printing Process for Low-Cost Solar Cell

Abstract:

Cu₂ZnSnS₄ (CZTS) film was prepared by screen printing process with the advantages of simple, high-effective and cost-effective. The annealing effects on the screen printed CZTS films were studied. It was found that the crystallinity of the CZTS can be effectively improved by the annealing process, whereas overlong annealing can also introduce defects to the CZTS. The bandgap value of the CZTS is about 1.4 eV. The short-circuit current density, open-circuit voltage, fill factor and conversion efficiency of the best solar cell with superstrate structure of Carbon/CZTS/In₂S₃/TiO₂/FTO glass (without using any vacuum conditions) are 6.20 mA/cm², 290 mV, 0.29 and 0.53%, respectively.
