Abstract Organic-inorganic hybrid halide perovskites based on CH3NH3PbI3 and related materials have emerged as the most exciting development in the next generation photovoltaic technologies. Here, the growth of concentric and colorful periodic ring perovskite CH3NH3PbI3 films using a sequential two-step deposition is investigated in detail. The appearance of the ringed perovskite films is mainly tuned by the CH3NH3I solution concentration during the drop coating process. The perovskite films composed of annular areas with different color contrasts, which accounts for the concentric and regular rings. The crystallization-depletion mechanism gives rise to a concentration gradient and a preferential ringed crystallization of the perovskite. The radius and spacing of these rings can be tuned by the substrate temperature and the drop height. Solar cells based on these films still show decent power conversion efficiencies over 17%. These present findings significantly enhance our understanding of the sequential two-step deposition perovskite films and feature the fabrication of special solar cells.
