Optimizing SCAPS model for perovskite solar cell equivalent circuit with utilizing Matlab-based parasitic resistance estimator algorithm

Abstract

Perovskite solar cells (PSCs) showed a booming trend due to its tunability as well as simplicity in fabrication. Researchers invested in exploring an appropriate equivalent circuit capable of describing the J-V curves of the PSCs as well as illustrating the physical phenomena associated with optical absorption and carrier transportation. In the same context, we propose a modified SCAPS model to demonstrate the optoelectronic behavior of PSCs through estimating the parasitic elements in the form of resistive and capacitive components. A previously reported PSC was selected as a reference where our enhanced model recorded only 4% mismatching. J-V, E-K and C-V curves have been simulated and analyzed where the appearance of the capacitive impact due to E-K charge accumulation has been addressed.
