Perovskite Films The image illustrates the synergy between fluid dynamic simulations and large-area meniscus coating processes. The bottom streamlines represent the theoretical modeling of precursor flow, which directly informs the precision of the bar-coating process shown in the center. This optimized deposition leads to the formation of highly ordered spherulitic crystal structures (top-left inset), paving the way for efficient and scalable perovskite solar cells.
