Effect of Series Resistance and Temperature on PCE of Double Perovskite La2NiMnO6‐Based PSC

Abstract

AbstractIn the present work, lead‐free double perovskite material La2NiMnO6 is used as a light‐harvesting layer in device configuration of FTO/TiO2/LNMO/CuI/Au and simulates through solar cell capacitance simulator (SCAPS‐1D). The series resistance and operating temperature are varied from 0 to 6 Ω and 250 to 350 K respectively to investigate the device output under ambient atmospheric conditions. The designed perovskite solar cell (PSC) based device helps to optimize the chemical and physical parameter of PSC during the fabrication. The present study exhibits that the developed device can show maximum power conversion efficiency (PCE) of 23.07% at the device approach to zero resistance and further, at operation temperature 250 K the device has shown superior PCE 26.79%.
