Abstract
Perovskite nanocrystals (PNCs) have emerged as a versatile platform for next-generation optoelectronics owing to high photoluminescence quantum yields, tunable bandgaps, and superior charge transport. Yet, the intrinsic disorder of colloidal systems and limitations of scalable processing severely restrict their performance. The structurally ordered PNCs, called herein as OPNCs, has emerged as a promising strategy to overcome the intrinsic limitations of disordered colloidal systems. Controllable self-assembly enables the formation of ordered superlattices, where collective effects such as enhanced carrier mobility, improved photoluminescence, and miniband formation can be realized. In this perspective, we highlight recent advances in solvent engineering, functionalized ligand design, and external-field modulation that provide new levers for achieving structural control. We further…
