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.
