Abstract

In this research work, a solar cell capacitance simulator (SCAPS-1D) was used in the modeling and simulation of sandwiched perovskite solar cells (PSCSs) with a planar heterojunction structure in the arrangement of the sandwiched model (FTO/ZnO/CZTS/PSCS/CZTS/HTM). Two different configurations, 121 and 111, of the sandwiching absorber layer of the device were simulated and compared with the perovskite without sandwiching, using an absorber layer of step length thickness of 25 nm, and varied from 100 nm to 500 nm. The band gap diagram, I-V characteristics curve, and other parameters were constructed. The best configuration for better performance was then determined, from which further simulations were carried out. Efficiency of 22.57% was achieved, which shows that having a combination of two different absorbers was achievable with considerable photon conversion efficiency.
