Cu2ZnSnS4 (CZTS) absorber layer research shows extensive influential factors to replace expensive Copper Indium Gallium Selenide (CIGS) absorber layer due to its high efficiency, low-cost, non-radioactive and environmental friendly behavior. Potential buffer layers for CZTS solar cells like ZnO, ZnS, In2S3 and ZnSe along with conventional CdS buffer layer are numerically analyzed. Among these structures, ZnS/CZTS structure shows an optimum efficiency of 26.82% (with Voc = 0.724 V, Jsc = 53.312 mA/cm 2 and fill factor = 69.44 %).This paper explicitly reveals the most favorable CZTS layer thickness around 2.5 μm, whereas buffer layer thickness lies just below 50 nm. Absorber carrier density has its effect on Voc and Jsc and so on efficiency. With increasing carrier density Jsc decreases while Voc increases. An optimum density of 5×10 17 cm to 1×10 cm shows a great result. The achieved results can lead to the development of higher efficiency CZTS thin film solar cells. (Avoid the words in abstract Ex.
