      abstract     = {Incorporating large organic cations to form 2D and mixed
                      2D/3D structures significantly increases the stability of
                      perovskite solar cells. However, due to their low electron
                      mobility, aligning the organic sheets to ensure unimpeded
                      charge transport is critical to rival the high performances
                      of pure 3D systems. While additives such as methylammonium
                      chloride (MACl) can enable this preferential orientation, so
                      far, no complete description exists explaining how they
                      influence the nucleation process to grow highly aligned
                      crystals. Here, by investigating the initial stages of the
                      crystallization, as well as partially and fully formed
                      perovskites grown using MACl, the origins underlying this
                      favorable alignment are inferred. This mechanism is studied
                      by employing 3-fluorobenzylammonium in quasi-2D perovskite
                      solar cells. Upon assisting the crystallization with MACl,
                      films with a degree of preferential orientation of $94\%,$
                      capable of withstanding moisture levels of $97\%$ relative
                      humidity for 10 h without significant changes in the crystal
                      structure are achieved. Finally, by combining macroscopic,
                      microscopic, and spectroscopic studies, the nucleation
                      process leading to highly oriented perovskite films is
                      elucidated. Understanding this mechanism will aid in the
                      rational design of future additives to achieve more defect
                      tolerant and stable perovskite optoelectronics.},
