Abstract

Abstract The migration of multiple chemical species is are main factor leading to the intrinsic instability of perovskite solar cells (PSCs). Herein, a universal ion migration suppression strategy is innovatively reported to stabilize multiple functional layers by simultaneously suppressing the migration of multiple mobile chemical species based on host–guest interaction via calixarene supramolecules. After incorporating 4‐tert‐butylcalix[8]arene (C8A), the interfacial defects are passivated, suppressing trap‐assisted nonradiative recombination. Moreover, the p‐doping of Spiro‐OMeTAD is facilitated, and the extraction and transport of holes are promoted for n‐i‐p regular PSCs. The C8A doped regular devices…
