Hybrid organic-inorganic perovskites have become one of the leading materials in
photovoltaics, although their instability under operating conditions interferes with practical
applications. This can be overcome by using tailored organic systems that interact with hybrid
perovskite frameworks through various noncovalent interactions, which predominantly involve
aromatic π-based systems as interfacial modulators or spacers forming layered hybrid
perovskites. We demonstrate the unique capacity to broaden this material space by relying on
unorthodox σ-hole-based interactions that can enhance the functionality of hybrid perovskites,
improving their operational stability without compromising photovoltaic performances,
providing a versatile supramolecular strategy for advancing hybrid photovoltaics.
