Numerical simulation has been performed to improve the performance of Cu2ZnSnS4(CZTS)solar cells by replacing CdS with Zn1-xSnxO buffer layer.The influences of thickness,donor concentration and defect density of buffer layers on the performance of CZTS solar cells were investigated.It has been found that Zn1-xSnxO buffer layer for Sn content of 0.20 is better for CZTS solar cell.A higher efficiency can be achieved with thinner buffer layer.The optimized so-lar cell demonstrated a maximum power conversion efficiency of 13%.
