T
he 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 “121 and 111” 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.
