Metal halide perovskites and 2D materials are innovative semiconductor materials with notable properties, and their heterostructures show significant advancements in both efficiency and stability. However, there are still challenges in developing these heterostructures for reliable use.
Metal halide perovskites, emerging innovative and promising semiconductor materials with notable properties, have been a great success in the optoelectronic and photocatalytic fields. At the same time, two-dimensional (2D) materials, including graphene, transition metal dichalcogenides (TMDCs), black phosphorus (BP) and so on, have attracted significant interest due to their remarkable attributes. While substantial advancements have been made in recent decades, there are still hurdles in enhancing the performance of devices made from perovskites or 2D materials and in addressing their stability for reliable use. Recently, heterostructures combining perovskites with cost-effective 2D materials have exhibited significant advancements in both efficiency and stability, attributed to the unique properties at the heterointerface. In this review, we provide a thorough overview of perovskite and 2D material heterostructures, spanning from synthesis to application. We begin by detailing the diverse fabrication techniques, categorizing them into solid-state and solution-processed methods. Subsequently, we delve into the applications of perovskite and 2D material heterostructures, elaborating on their use in photodetectors, solar cells, and photocatalysis. We conclude by spotlighting existing challenges in developing perovskite and 2D material heterostructures and suggesting potential avenues for further advancements in this research area.
