Abstract
The absorber layer of CZTS solar cell is a compound semiconductor which has favourable optical and electrical properties. Researchers are highly interest to investigate the CZTS solar cells for its earth abundant, non-toxic and low cost feature. Consequently, the absorber layer of CIGS is replaced to CZTS absorber layer. In this research work, the potentiality of Molybdenum Sulphide (MoS2) as buffer has been investigated to explore the higher performance of CZTS solar cells. SCAPS 2802 simulator was used to evaluate the performance of CZTS solar cells with prospective MoS2 buffer layer. The possibility of ultra-thin CZTS solar cells was examined and the higher efficiency of 17.03% (Jsc = 29.42 mA/cm 2 , Voc = 1.01 V and FF = 0.574) was achieved for 1 μm thickness of absorber layer. In addition, the proposed CZTS solar cells had better thermal stability at higher operating temperature also.
