Abstract

The solar cell capacitance simulator (SCAPS-1D) was used in the modeling and simulation of sandwiched Perovsk-ite solar cells (PSCs) with planar hetero-junction structure in the arrangement of the sandwiched model (FTO/ZnO/CZTS/PSCS/CZTS/ HTM). Two different configurations â�?�?121 and 111â�? of sandwiching absorber layer of the devi-ce were simulated and compared with the Perovskite without a sandwich, using absorber layer of step length thickn-ess of 25nm, and varied from 100nm to 500nm. The band gap diagram, I-V characteristics curve, and other param-eters were constructed. The best configuration for better performance was then determined, from which further sim-ulations were carried out. The efficiency of 22.57% was achieved, which shows that having a combination of two different absorbers was achievable with considerable photon conversion efficiency.
