stable, efficient inverted perovskite solar cells enabled by the multifunctional ytterbium oxide buffer

science China Chemistry 2024年第8期67卷 2423-2424页

作者： Manman Hu sang il seok Department of Energy and Chemical Engineering Ulsan National Institute of Science and TechnologyUlsan 44919Republic of Korea

significant advancements in single-junction inverted perovskite solar cells (PsCs) have led to power conversion efficiencies (PCEs) exceeding 25% [1]. However, their operational stability under strict conditions falls short compared with commercial solar panels, primarily due to the ion migration. This migration alters the chemical composition within the perovskite layer, increasing the heterogeneity and forming degradation sites [2]. Additionally, ion accumulation at metal interfaces corrodes electrodes, while metal diffusion into perovskite layers further compromises the stability, highlighting critical areas for the improvement in long-term device performance [3,4].
