Abstract
Metal halide perovskites (MHPs) show optoelectronic properties that are highly advantageous for light-emitting applications. Compared to polycrystalline (PC) perovskite, single-crystal (SC) perovskite exhibits high carrier mobility, reducing ion migration and suppressing Auger recombination. However, SC perovskite light-emitting diodes (SC-PeLEDs) face the following challenges: i) the growth of high-aspect-ratio SC films; ii) the interfacial contact between the SC light-emitting layers and the carrier transport layers. This review begins with the growth methods of MHP SC thin films. Then, the recent research progress of SC-PeLEDs is summarized, and the strategies for optimizing device performance are also reviewed. Finally, perspectives are proposed further to enhance the performance and practical application of SC-PeLEDs.
