Immobilizing Lead and Healing Surface Defects via Perfluorinated Tertiary Amine Molecules Enables High‐Performance Sustainable Inverted Perovskite Solar Cells

via a strong coordination bond, which is favorable for suppressing lead leakage and promoting defect passivation. Due to much reduced surface nonradiative recombination, the PFTEA-modulated inverted PSCs deliver a fascinating certified stabilized power conversion efficiency (PCE) of 26.65%, a record efficiency value reported for PSCs using the vacuum flash evaporation technique. Moreover, the PFTEA-modulated devices maintain 92% of their initial PCE after 1000 h of continuous maximum power point tracking. This work provides a simple and effective avenue to advance the sustainable development of inverted photovoltaic technology through a perfluorination strategy.
