Implementing an intermittent spin-coating strategy to enable bottom-up crystallization in layered halide perovskites

Random orientation of layered crystals in 2D perovksites impedes the out-of-plnae carriers transport and hence undermines the photovoltaic perofrmance. Here, the authors discover that the crystallisation can be regulated by intermittent spin-coating strategy.
