Solar to power conversion certified efficiencies of formamidinium lead iodidebased single-junction perovskite solar cell is now 26%, allperovskite-perovskite tandem $\sim$28%, and the perovskite-silicon tandem solarcell is $\sim$34% going beyond gallium arsenide solar cells. Therefore, it isnow one of the most promising materials for generating cheaper sunlight-basedelectricity. This material has two commonly known polymorphs; one is athermodynamically stable yellow hexagonal phase. The other one is a metastableblack perovskite phase: a powerful photo-active material. Thousands ofexperiments have been performed to produce the highly crystalline photoactivephase of formamidinium lead iodide. Despite that, PSCs often suffer from poorreproducibility and stability. One of the root cause is the lack of controlover their synthesis, i.e. crystallization process, where one of the mainquests is to synthesize and stabilize corner-sharing defects-free photoactiveperovskite form of pure or doped black perovskite form of formamidinium leadiodide and prevent the formation of hexagonal phases. Thus, for the rapidindustrialization of perovskite based solar farms to combat global risingtemperatures: it is all-important to understand the polymorph selectivenucleation of formamidinium lead iodide from its precursors. Towards thisultimate goal, here we perform molecular simulations of the nucleation offormamidinium lead iodide from solution. This study aims to take the primarysteps for the all-atoms simulations of the polymorph selective crystallizationof halide perovskites.
