Abstract Migration of ions can lead to photoinduced phase separation, degradation, and current–voltage hysteresis in perovskite solar cells (PSCs), has become a serious drawback for the organic–inorganic hybrid materials (OIPs). Here, inhibition ion migration is realized by supramolecular cation–π interaction between aromatic rubrene organic cations OIPs. The energy found be as strong 1.5 eV, which enough immobilize OIPs; this will thus obvious reduction defects films outstanding stability...

Abstract Perovskite solar cells (PSCs), while highly efficient, face stability challenges that hinder their commercial application. These instability issues mainly arise from the fragile nature of Pb─I bonds in perovskites, which easily break under environmental stresses such as heat and light, leading to breakdown [PbI 6 ] framework irreversible degradation.
