Metal halide perovskites: a platform for next-generation multifunctional devices

Abstract

Abstract Metal halide perovskite materials have rapidly advanced as a pivotal class of promising candidates suitable for a broad spectrum of next-generation technologies owing to their exceptional optoelectronic properties, intrinsic tolerance to crystallographic defects, and structural versatility together with decades of progressive discoveries further driven by their compatibility with cost-effective solution-based fabrication techniques. In particular, the rapid advancement in perovskite solar cells—now achieving champion power conversion efficiencies (PCEs) of up to 27% for single junction and 34.6% for tandem architectures with silicon—has fueled growing interest in leveraging their potential beyond photovoltaics. This includes expanding their applications into diverse fields outside optoelectronics such as energy storage and conversion, catalysis, neuromorphic computing, and other emerging innovations such as quantum technologies. Accordingly, this review provides a comprehensive overview of emerging trends and latest breakthroughs in the application of metal halide perovskites across diverse domains, including solar cells, light-emitting diodes (LEDs), photodetectors, X-ray and gamma-ray detectors, memristors, thermoelectrics, sensors, lasers, triboelectric nanogenerators, supercapacitors, batteries, catalysts, and quantum technologies. Also discussed are the fundamental working principles underlying these applications, recent progress and innovations across each domain, and critical assessments of the prevailing challenges that continue to hinder their large-scale adoption. Ultimately, this article presents holistic perspective on state-of-the-art developments in various application fields of metal halide perovskites and outlines strategic directions aimed at facilitating the future commercialization of metal halide perovskite-based technologies.
