Advancing Tin‐Based Perovskite Emitters for High‐Performance Displays: Strategies, Challenges, and Future Prospects

Abstract Metal halide perovskites have emerged as a highly promising material for light‐emitting applications, but concerns about lead toxicity have spurred eco‐friendly alternatives. Tin‐based perovskites have gained particular attention because of their unique properties, which are well suited to high‐definition display applications. In this review, a comprehensive analysis of tin‐based perovskite emitters is presented, with particular attention to their structural characteristics and optoelectronic properties. Additionally, recent advancements in tin‐based perovskite light‐emitting diodes are highlighted, emphasizing a number of strategies for improving device efficiencies, including inhibiting oxidation, optimizing crystallization processes, customizing device structures, and engineering A‐site cations. Finally, potential strategies to overcome the challenges associated with tin‐based perovskite light‐emitting diodes in applications requiring full‐color displays are discussed. These insights offer a roadmap for advancing full‐color, high‐performance displays using tin‐based perovskites.
