Operational Stability Management Approaches for Perovskite Solar Cells

Perovskite solar cells (PSCs) rapid progress is driven by their exceptional optoelectronic properties. Transitioning to commercialization resolves efficiency and cost concerns, focusing on addressing the critical challenge of a limited operational lifetime under environmental aging. Modified International Electro-technical Commission (IEC) testing standards provide a robust foundation for assessing PSC stability. Some PSCs pass tests with enhanced films, advanced architectures, and effective stabilization methods. The ionic and soft nature of perovskites introduces challenges like ion transportation and phase separation. Developing functionally steady PSCs is crucial for commercializing perovskite PV technologies. Standardizing testing processes and reporting for stability results is essential, requiring detailed experimental procedures. The research community’s intensified focus anticipates rapid improvements in operational stability, mirroring progress in PSC efficiency and facilitating commercialization.
