Epitaxial growth technology has drew widespread attention in the field of perovskites because of its notable success to produce high-quality crystals with preferred orientations and superior photoelectric properties, which enables the material combinations with a coherent interfacial lattice as well as combined complementary functionalities. Besides, the minimized structural defects benefited from the lattice coherent and the adjustable residual strain level could profoundly impact the energy conversion performance of perovskite epitaxial structures and their assembled devices. In this review, we summarized the lattice-matched epitaxial structures of perovskite solids categorized by the combined materials and demonstrated their lattice-matched schemes as well as the performance in various devices. Finally, we outline future directions for perovskite epitaxy, focusing on precise interfacial structure characterization and scaling up fabrications. These advancements have the potential to further enhance the performance and applications of perovskite-based devices.
