摘要: In recent years, metal-organic frameworks (MOFs) have emerged as promising materials in modifying perovskite solar cells (PSCs) due to their unique porous structures, exceptional specific surface area, tunable organic–inorganic coordination environments, and abundant modification sites. These features endowed MOFs with the ability to regulate the crystallization rate of perovskite films, promote uniform crystal growth, and passivate both surface and grain boundary defects. This review systematically categorizes the applications of MOFs in PSCs based on MOF types and their corresponding functional mechanisms, while exploring the selection criteria for MOFs with different structures from five key dimensions: pores, framework structures, functional groups, MOF composites, and MOF derivatives. Focusing on the structural design of MOFs, this review further aims to forecast the development trends of MOFs at the MOF/PSCs interface and provide guidance for the rational design and selection of MOFs for propelling next-generation photovoltaic technologies.
