Regulating lattice evolution via an ordered two-dimensional intermediate phase for resilient perovskite solar cells
The dynamic expansion and contraction of metal halide hybrid perovskite lattices during day-night cycling generate severe mechanical strain, accelerating trap accumulation and device degradation. Here, we show a strain-regulation strategy that employs a highly oriented two-dimensional (2D) perovskite, 1-(p-fluorophenyl...
