Abstract: As perovskite solar cells are highly efficient and already meet the efficiency requirement for renewable powergeneration, more attention is given to technological barriers such as scalability and stability. In particular, thelarge efficiency losses associated with upscaling lab-scale devices to large-area modules represents one ofthe major hurdles for commercialization. Given the essential role of the perovskite films in the deviceperformance, it is of critical importance to develop reliable crystallization protocols to deposit high-qualityperovskite layers via scalable methods. This review summarizes recent advances in emerging crystallizationprotocols for the large-scale deposition of perovskite thin films. The unique merits of the well-developedcrystallization strategies, including antisolvent, gas quenching, vacuum quenching, etc., are carefully analyzedand discussed. We highlight that, independent of the coating method, creating intermediate phases todecouple the otherwise overlapped solution coating and crystal growth is essential to realize homogeneouscoatings of perovskite thin films. Strategies for enhancing the crystal morphology of perovskite films arepresented as well, which is vitally important to realize reproducible manufacturing of large-area modules. Thistutorial review assists the screening and development of robust crystallization strategies for scalabledeposition of high-quality perovskite films for photovoltaic applications.
