Self‐Healing Ionogel Dual‐Network Enables Synergistic Defect Passivation and Strain Relief for High‐Efficiency Robust Perovskite Photovoltaics

Advanced Science, EarlyView.
PSCs are afflicted by inherent defects and lattice strain that limit PCE and stability. A cross‐linked multifunctional ionogel [HA‐AA][EMIES] is developed to modulate crystallization, relieve residual strain, and passivate defects, extending carrier diffusion length to over 8 µm and delivering PCEs of 26.45% for rigid devices and 25.14% for flexible ...
