In this paper, the effect of temperature on CZTS (Cu2ZnSnS4) thin film solar cell performance has been numerically investigated using Solar Cell Capacitance Simulator (SCAPS-1D). We have evaluated the temperature dependence of the energy band gap (Eg) of CZTS solar cell layers (ZnO, CdS and CZTS) between 300 and 350 K by Varshni formula. A decreased trend of Eg has been noticed with an average band gap narrowing coefficients around 1.48 ( 10 – 4, 3.61 ( 10 – 4 and 7.37 ( 10 – 4 eV/K for ZnO, CdS and CZTS, respectively. The obtained results reveal that Jsc increases, but Voc and FF decrease with respect to temperature. As a result, the efficiency falls from 12.08 % at 300 K to 11.87 % at 350 K with a coefficient variation of – 0.036 %/K. 300 K operating temperature is considered more appropriate to achieve high performances and get maximum efficiency under AM 1.5 G (1000 W/m2) solar spectrum.
