Abstract In the past few years, metal halide perovskite solar cells (PSCs) have attracted widespread attention in the photovoltaic field, and their power conversion efficiency has rapidly exceeded 25%. Among the adopted effective strategies to realize the high efficiency, the introduction and utilization of ordered array structure in the PSCs are particularly prominent, which can simultaneously enhance light harvesting efficiency and carrier transport properties by manipulating the light paths (reflection, scattering, extraction, and propagation) and constructing direct charge transport paths. The full utilization of sunlight contributes to high short‐circuit current density ( J sc ), and strong carriers transport is favorable for high charge collection and reducing charge recombination. Moreover, for flexible PSCs, ordered array structured device can be greatly relaxed during bending, thereby suppressing the formation of cracks in PSCs. Herein, this article focuses on the ordered array structure design, reviews the recent research progress of the ordered array structures in PSCs, and provides some promising perspectives for further improvement.
