Ruddlesden-Popper quasi-2D perovskites represent robust candidates for optoelectronic applications, achieving a delicate balance between outstanding photoresponse and stability. However, mitigating the internal defects in polycrystalline films remains challenging, their performances still lag behind that of 3D counterparts. This work highlights profound impact defect passivation at buried interface grain boundaries through dual-cation-release strategy. Cations released from pre-deposited inorganic iodide buffer layer effectively repair deep-level by inducing low-dimensional phase reconstruction interacting with undercoordinated ions.
