Imidazolium Ionic Liquid-Modified Perovskite Solar Cells and Its Performance Characteristics
摘要
Abstract
Wide-bandgap perovskite solar cells are a key component of silicon-perovskite tandem solar cells.However,the development of wide-bandgap perovskite solar cells has been hindered by issues such as high defect density and severe non-radiative recombination in wide-bandgap perovskite materials.To address these issues,this study proposes a method for modifying perovskite films using the ionic liquid 1-butyl-3-methylimidazolium methanesulfonate(BMM).By investigating the effects of different BMM concentrations on perovskite films and their solar cell performance,it is found that optimizing the BMM additive amount can enhance crystallization quality and reduce internal film defects,thereby improving the performance of perovskite solar cells.Under optimal conditions,the perovskite solar cells achieved an efficiency of 20.27%,with significant improvements in various optoelectronic properties and excellent stability.These results strongly demonstrate that BMM,as an effective additive,holds great potential for the fabrication of high-quality perovskite films and the realization of high-performance devices,providing important insights references for future practical applications.关键词
