Selective Ion‐Blocking Strategy for Stabilizing Perovskite Tandem Solar Cells
Advanced Energy Materials, EarlyView.A selective ion‐blocking Li─T interlayer is introduced at LiF‐passivated perovskite interfaces to suppress fluorine diffusion while preserving the beneficial interfacial passivation of LiF. This ion‐blocking strategy markedly improves the long‐term operational stability of both single‐junction and monolithic all‐perovskite tandem cells under continuous
