Optoelectronic Study of Polymer Electrolyte Incorporated Perovskite Sensitized Solar Cell

Abstract

AbstractPerovskite solar cells have appeared as a leading next‐generation photovoltaic technology. However, notwithstanding rolling efficiencies, many questions remain unreciprocated regarding the mechanisms and performance of the operation. Solution‐processed organic‐inorganic hybrid perovskites have fascinated attention as light‐harvesting materials for perovskite solar cells and photonic applications. The present study focuses on the optical and electronic study of CH3NH3PbBr3 and CH3CH2NH3PbI3 perovskite fabricated by a one‐step solution‐based self‐assemblage method. It is seen that in this study, methyl group represents a better performance than ethyl‐based perovskite‐sensitized solar cells (PSSCs). All the studies centralize on electro‐optical properties of efficient CH3CH2NH3PbI3 and CH3CH2NH3PbI3 PSSC based on polymer electrolytes. It has also characterized lab synthesized perovskite samples by scanning electron microscopy (SEM), UV–vis spectrophotometer, and photovoltaic performance of lab fabricated PSSC is measured by Keithley 2400 resource meter. These findings establish systematic strategy rules to attain silicon‐like efficiencies in simple perovskite solar cells.
