摘要
Hybrid organic-inorganic perovskites(HOIPs)have attracted great research interest as promising materials for the next generation photovoltaic energy harvesting,electro-optic detection,and all-optical conversion.Their remarkable chargetransport and absorption properties are underpinned by hybrid perovskite atomic structures.Understanding the atomic structure and structural instability of organic-inorganic hybrid perovskites is the key to appreciate their remarkable photoelectric properties and understand failure mechanism.
