Bandgap-tunable mixed-halide perovskites offer exciting opportunities to construct efficient multijunction tandem solar cells. However, the ion migration always causes halide segregation, which inevitably creates detrimental defects and deteriorates photovoltaic performances. Here, we report a universal caging strategy suppress segregation by in situ formation of conjugated covalent organic frameworks (COFs) catalyzed PbX2 (X = Br I) during perovskite. Through theoretical calculation systematic investigation, strong electron-donating feature COFs is shown effectively solidify soft lattice impede iodide transport from bulk grain boundary, decelerating light-induced halide-demixing process. Finally, nonradiative recombination significantly reduced, boosting efficiency up 11.50% for an inorganic CsPbIBr2 perovskite cell 14.35% CsPbI2Br with prolonged shelf life improved photostability.

Over the past decade, perovskite photovoltaics have approached other currently available technologies and proven to be most prospective type of solar cells. Although many‐sided research in this very active field has generated consistent results with regard their undisputed consistently increasing power conversion efficiency, it also produced several rather contradictory opinions. Among important details, debate surrounding proneness surface degradation poor mechanical robustness, as well environmental footprint materials class, remains a moot point. The application ionic liquids appears one potential remedies some these challenges due high conductivity, opportunities for chemical “tuning” structure, relatively lower footprint. This article provides an overview, classification, applications We summarize use role versatile additives, solvents, modifiers precursor solution, charge transport layer, interfacial stability engineering. Finally, future prospects design and/or selection specific profile that meets requirements next‐generation highly efficient stable cells are proposed.
