Abstract:

Owing to fascinating properties including high photon absorption coefficient, low exciton binding energy and high carrier mobility, as well as unique merits including excellent defect tolerance, enabling solution growth at low temperature, and feasibility in band gap tailoring, halide perovskites have attracted significant attention and emerged as one of hot topics in the area of optoelectronics. Exploring perovskite micro/nano-arrays on the basis of existing single micro/nano-wire device would undoubtedly promote their applications in the high-performance integrated (flexible) optoelectronics devices. Unfortunately, poor resistance of halide perovskite to general chemical agents (including water) hinders their integration by traditional photolithography process. Therefore, novel lithographic methodologies are highly required. This review briefly outlines the state-of-the-art progress on the synthesis of halide perovskite micro/nano-arrays, analyzes their merits, and depicts the recent progress of micro/nano-arrays in the area of optoelectronic devices. Finally, the challenges in the current stage and the development prospects in future are discussed to provide useful guidance in exploring novel perovskite based integrated devices in future.
