From left to right: additive = none, LiCl, NH4Cl, CsBr, PbBr2. From top to bottom: solvent ratio = 1:1, 1:4, 0:1, 1:0. Black: bare systems. Red: solvent red. Green: solvent blue. Blue: oil black. Yellow: calcein. a–e Molecule-modified perovskite systems with fixed solvent ratio (1:1) and variable additives and post-treatment dyes. f–j Molecule-modified perovskite systems with fixed solvent ratio (1:4) and variable additives and dyes. k–o Molecule-modified perovskite systems with fixed solvent ratio (0:1) and variable additives and dyes. p–t Molecule-modified perovskite systems with fixed solvent ratio (1:0) and variable additives and dyes.
