Traditional oxide ferroelectrics have long struggled to produce flexible, large-area, and high-quality thin films at low temperatures, despite their good piezoelectric activity. Organic-inorganic hybrid perovskite (OIHPFs), by contrast, are gaining popularity as promising candidates for next-generation flexible self-powered electric devices due easy solution-processability, structural adjustability, mechanical flexibility, superior performance. However, practical use is hindered a lengthy single-crystal growing period the absence of truly effective large-area film manufacturing technique. To address these challenges, simple electrohydrodynamic (EHD) printing technology first proposed in situ manufacture OIHPF crystals or without substrate size limitations. The obtained TMCM-CdBrCl2 has high coverage 99.83%. Notably, it crystallinity 80.35% coefficient that 72% 5.8 times higher than non-EHD-printed sample, respectively. nanogenerator (PENG) based on this can endure over 200 000 bending cycles-the highest value recorded date. This approach also shows strong feasibility broad applicability creating different crystals, providing valuable scientific insight large-scale integrated development OIHPF-based electronics.

Abstract Owing to distinctive properties of lightweight, thin, high energy‐to‐mass ratio and bendability, flexible perovskite solar cells (f‐PSCs) are expected extend the application scenarios photovoltaics, while defective fragile interface within devices seriously restricted their mechanical stability practical deployment. Herein, origin flexibility lattice is explored historic progress f‐PSCs briefly summarized. Then, fracture mechanics relevant characterizations introduced. Recent strategies boost durability systematically reviewed from aspect design, including regulation crystallization with optimum crystallinity suppressed strain, construction grain boundary patches eliminate difference between boundaries, facilitating energy dissipation adjacent elastic layers, strengthening interfacial contact improved resistance. In end, perspectives in further development toward efficient mechanically robust provided.
