Halide perovskites offer a transformative potential for optoelectronics through tailoring the light-matter interactions at the nanoscale. However, their susceptibility to environmental factors and limited compatibility with standard lithography techniques present significant challenges in precise nanopatterning. This work unveils a nature-inspired breath figures (BFs) approach to pattern halide perovskites and enhancing their optoelectronic performance. The fabrication of BFs based on BiI3 allows for changes in nanopore size (ranging from 247 to 423 nm) and their distribution. Subsequently, these BiI3 BFs are transformed into hybrid halide MA3Bi2I9 BFs using a vapor-assisted technique while retaining the nanoporous topology of the BiI3 structure. The resultant MA3Bi2I9 BFs show significantly enhanced light absorption compared to conventional thin films, attributed to the increased extinction and lower refractive index. The optoelectronic performance of the MA3Bi2I9 BFs is showcased by constructing a photodetector, which exhibits three orders of magnitude higher responsivity and detectivity, up to 1 AW−1 and 1.3 × 1012 Jones, respectively, outperforming the photodetectors based on solution-processed A3B2I9 halide perovskite thin films. The BFs method provides flexibility in tuning nanoscale morphology, showcasing its potential in advancing lead-free optoelectronics and paving the way for next-generation optoelectronic devices.
