Abstract: Hybrid organic-inorganic perovskites (HOIPs) have received intensive attention from scientific communities worldwide. Solar cells based on HOIPs have made spectacular progress in less than 10 years. The unprecedented improvement depends on the quality improvement of the perovskites, which is determined by their crystallization process. In this work, the crystallization process of the HOIPs in forms of single crystal and polycrystalline film is systematically investigated. It was studied that two factors, the supersaturation and interfacial energy, play important roles in the crystallization process. Modification of these factors is able to change the crystal growth orientation of the single crystals and grain size of the polycrystalline film. A method based on the control over the crystallization has been established to achieve high efficiency of perovskite solar cells. The study can help us to get a better understanding of the crystallization process and have a better control over the quality of the HOIPs.
