Abstract

A cyano-based DCI additive induces phase-buffering during the crystallization growth process of 2D halide perovskites, which effectively suppresses interphase strain, enhances lattice orientation and reduces trap-state density, delivering an outstanding and stable efficiency of ∼17.0% ( n = 4).
