摘要：

Conventional antisolvent dripping methods face fundamental limitations in controlling crystallization kinetics, particularly manifesting as instantaneous nucleation and severe spatial inhomogeneity in scaled-up perovskite films. Herein, a microdroplet-phase antisolvent deposition technique is developed that establishes a controlled crystallization environment through delayed nucleation kinetics via mild antisolvent interaction and uniform microdroplet diffusion across extended substrates. The resulting small-area (0.1 cm²) device attains an external quantum efficiency (EQE) of 30.98% at 515 nm, ranking among the best-performing green perovskite light-emitting diodes (PeLEDs). A remarkable EQE of 23.21% is also realized when the active area expands to 6.25 cm². This work provides a fundamental advancement in perovskite crystallization control and demonstrates a viable pathway toward industrial-scale production of PeLEDs.
