Spiro‐Buckybowl‐Structured Hole‐Transporting Materials Toward High‐Efficiency and Stable p–i–n Perovskite Solar Cells
) passivation, leading to effective perovskite crystallization. Specifically, the Sp-S enables superior hole transport and a stabilized buried interface, yielding a champion efficiency of 25.54% (certified at 25.36%) and exceptional operational stability with 92.5% retention over 1250 h under continuous light illumination at 65°C (ISOS-L-2). The spiro-buckybowl molecular structure establishes a new design paradigm for organic semiconductors, offering a versatile platform for perovskite photovoltaics.
