Abstract
Kesterite Copper-Zinc-Tin-Sulphide (Cu2ZnSnS4) is a non toxic and earth abundant semiconductor compound with optimum band gap (1.3-1.5eV) and high absorption coefficient (104 cm-1). In this work firstly the modeling of CZTS solar cell is done by SCAPS 1D software and then layer parameters have been optimized and cell parameters like Voc, Jsc, FF and η are recorded for the best performance of solar cell. The cell structure simulated in this work is Mo/CZTS/CdS/i-ZnO in which CZTS works as an absorber layer, CdS works as buffer layer, i-ZnO as window layer and Mo is a back metal contact. We have optimized the effect of band gap (Eg), thickness of CZTS absorber layer. The effect of temperature is also studied in this work. The optimized values of CZTS thickness and band gap for the above structure are found to be 2.5μm and 1.4eV. The optimum temperature is 300K. By using these values the best performing solar cell in this work gave Voc= 0.44V, Jsc= 45.70 mA/cm2, FF=63.6% and η= 12.85%.
