Eliminated Interfacial Side Reactions in Perovskite Solar Cells by Sterically Protected Ammonium Passivation
. Moreover, the device with DMCHAI modification remains over 86% of its initial efficiency after 550 h of thermal stress at 85 °C. This work highlights the importance of deprotonation-resistant ammonium salts in constructing thermally stable perovskite interfaces and provides a rational design guideline for passivation materials in PSCs.
