Hybrid metal halide perovskite magic-sized clusters, what’s next?

In recent years, hybrid metal halide perovskites (MHPs) materials have shown great potential application prospects in photovoltaics, catalysis, biomedicine, and quantum information technology due to their excellent optoelectronic properties. However, the toxicity and stability of intrinsic MHPs have restricted their development and widespread application. In the MHPs material system, perovskite magic-sized clusters (PMSCs) with extremely fast variations of tiny-aggregated atomic/molecular level polymers ranging from dozens to several hundreds of atoms or molecules, as multi-nuclear aggregates between microscopic atoms/molecules and macroscopic MHPs crystal materials, are the smallest structural system for studying the precise structure construction, electron structure and evolution rules, and related optoelectronic applications of the MHPs materials. At the atomic/molecular level, studying the mesoscale structure and evolution properties, synthesis methods, modification strategies, quantum effects and optoelectronic applications of PMSCs in multi-scale crystal material systems is crucial for exploring the structural evolution mechanism of MHPs, revealing the design principles of MHPs multifunctional coupling materials, and designing and developing new high-efficiency optoelectronic MHPs materials and related prototype devices.
