Lead Halide Perovskites (LHPs) have garnered great attention in recent times due to their astonishing properties that range from direct tunable bandgaps, strong light absorption, defect resistance and the easily accessible synthesis of high‐quality crystals and films. These materials find application in multitudinous fields including photovoltaics, optoelectronics, lasers, catalysis and in the emerging field of spintronics. Though they show exceptional optoelectronic properties with enhanced applications, the instability of LHPs act as a main downside when it comes to real world applications. Integrating complementary materials to LHPs that form composites with better stability along with improved performance have started to gain traction. These composites and heterostructures incorporating functional materials with LHPs have made the utilization of perovskites in everyday life more feasible. The existing synthetic strategies for heterostructure and composites heavily draw from the techniques used for halide perovskite synthesis. These methods often under‐utilize the potential of exploring the synergy of materials interaction. This review explores the synthesis methods followed to produce these hybrid materials focusing on the improvements required in terms of fundamental studies and their applications.
