“…Well-known poly(vinyl chloride) (PVC), polystyrene (PS), [110,111] poly(methyl methacrylate) (PMMA), [112] poly(acrylonitrile-co-butadiene-co-styrene) (ABS), [113] and polycarbonate (PC) (Figure 8) can act as substrates for the perovskites. All these polymers are amorphous, dielectric, commercially available and swell in DMF as perovskites.…”

“…[112,114] Hossain et al developed a spray coating method that stabilized MAPbBr 3 NCs in PS solution, which has a proper wettability to various rigid and flexible substrates. [111] PS provides additional optical and structural stability of perovskite NCs against polar solvents. Combining stable PS and unstable MAPbBr 3 NCs a double-layer fluorescent anticounterfeiting security tag was fabricated.…”

Future displays need to be stretchable, bendable, and wearable to match consumers’ needs for convenience, portable equipment, and real‐time information display. The development of flexible light source components, like flexible light‐emitting diodes (LEDs), is urgently required to fulfill these needs. Metal halide perovskites, known for their excellent optoelectronic properties and ductility, are considered the most promising light‐emitting materials for high‐definition displays, and their outstanding advantage is that the metal halide perovskites would be achieved by solution process under low temperature (<150 °C), which is especially good for the flexible organic substrates to maintain high conductivity during fabrication of flexible LEDs. In recent years, flexible perovskite LEDs have made significant progress, but still face a great deal of difficulties, obstacles, and great challenges. Herein, the mechanical properties of perovskite materials are examined and the failures for perovskite‐based flexible optoelectronic devices under strain are discussed. The authors then focus on optimizing each functional layer and the recent advancement in flexible perovskite LEDs is summarized. Finally, a brief outlook on the challenges faced by flexible perovskite LEDs and their possible future development is provided.

Lead-halide perovskites have come to dominate the emerging photovoltaics research scene over the past decade. But whilst perovskite photovoltaics exhibit exceptional efficiencies, their limited stability, as well as the toxicity of their lead component remain challenges. This Focus Collection captures a snapshot of the efforts in the community to address these challenges, from modifications to the synthesis and device structure of perovskite photovoltaics to improve their stability, through to efforts to understand, develop, and improve lead-free perovskite-inspired materials (PIMs). PIMs range from direct perovskite-derivatives (e.g., CsSnI3 or halide elpasolites) through to electronic analogues (e.g., BiOI). The Collection discusses the application of these materials not only for solar cells, but also more broadly for photodetection, light emission, and anti-counterfeiting devices. This collection emphasizes the diversity of strategies and directions in this field, as well as its highly interdisciplinary nature.
