Grain boundaries become fused following Dr. Jiang’s novel post annealing treatment

Comparison of grain boundaries in MAPbI3 perovskite films following thermal annealing (a), DMF solvent annealing (b), and methylamine post annealing treatment. The methylamine post annealing treatment shows the most improvement, as the grain boundaries become fused and less defined after application.
