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...
