%X The annealing of fine-grained (¡«0.175 ¦Ìm) ¡°yellow¡± ¦Ä-FAPbI3 nonperovskite thin films at 100 ¡ãC in dimethyl sulfoxide vapor for a few minutes results in exceptional grain growth (¡«5 ¦Ìm) induced by their transformation to the desirable ¡°black¡± ¦Á-FAPbI3 perovskite phase. Mechanistic insights into this unprecedented phenomenon are provided
