Effect of Band-Gap Tuning and Series Resistance on PCE of Optimized MAPbI3-Based PSC by SCAPS-1D Simulation

Organic-inorganic metal halide-based perovskite solar cell (PSC) is reaching more height day by day. Recent various efforts are applied by different researchers with experimental and theoretical studies to improve the device performance and stability of device. In the present work, MAPbI3-based PSC device is stimulated to under its behavior with variation in the band-gap of absorber and series resistance. The band-gap of absorber is varied from 1.3 to 2.5 eV and it has found that the simulated exhibited superior PCE of 25.76% at band-gap of 1.3 eV. Further, the variation in series resistance affects the device performance and found best device response under lower resistance. Additionally, the change in QE with variation in R-s is also analyzed.

Automated summary

The organic-inorganic metal halide-based perovskite solar cell (PSC) is continuously improving. Recent efforts from different researchers, both experimental and theoretical, have been made to enhance the device performance and stability. In this study, a MAPbI3-based PSC device was simulated to investigate its behavior with variations in the absorber's band-gap and series resistance. It was found that the simulated device exhibited a superior power conversion efficiency (PCE) of 25.76% at a band-gap of 1.3 eV. The device performance was also influenced by changes in the series resistance, with the best response observed under lower resistance. Moreover, the change in quantum efficiency (QE) with variations in the series resistance was also analyzed.
