Perovskite photovoltaics investigates halide and chalcogenide perovskite materials and device architectures for high-efficiency, stable solar energy conversion and related optoelectronic devices. Work in this area spans single-junction and multi-junction (perovskite–silicon, all-perovskite, and perovskite–CIGS) cells, with emphasis on defect passivation, interface and transport-layer engineering, compositional tuning, and microstructural control to enhance power conversion efficiency, operational stability, mechanical flexibility, and manufacturability, including scalable coating, module integration, recycling, and pathways toward commercial thin-film photovoltaic technologies.
