Narrative review demonstrates high-entropy perovskite synthesis and stability across energy devices, suggesting pathways for durable optoelectronics.
The widespread application of perovskites in fields such as photovoltaics, light‐emitting diodes, and catalysis has brought about new challenges related to environmental pollution. The development of stable and efficient perovskite materials has become a key technological breakthrough for ensuring human health and ecological safety. High‐entropy (HE) materials, due to their unique multi‐element composition, compositional tunability, and entropy stabilization, have opened new avenues for regulating the performance and expanding the functionality of perovskites. Therefore, we comprehensively summarize the latest research progress on HE perovskites (HEPs) in terms of structure, synthesis, and performance. Furthermore, we discuss the applications of HEPs in fields such as energy conversion and storage, optoelectronic devices, and catalysis. Finally, we outline the current technical challenges and future prospects for HEPs. Overall, this review aims to drive innovation and application in the field of HEPs, thereby advancing the development of next‐generation energy and electronic devices.
