Optoelectronic Study of Polymer Electrolyte Incorporated Perovskite Sensitized Solar Cell

Abstract

Perovskite 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.

Review on Functional Electrolyte, Redox Polymers, and Solar Conversions in 3G Emerging Photovoltaic Technologies: Progress and Outlook

“…Perovskite materials have long electron diffusion lengths and high absorption characteristic structures. − Recently, low cost perovskite solar cells are viewed as the next generation solar conversion (PCE >25%) system, which is an alternative of Si-based solar cells. , Focusing on the stability issue, using nonionic Au-NPs as dopants should be able to avoid the penetration of water molecules though P3HT. Dopants are incorporated to the hole transport structure to improve hole mobility.…”
