Popis:	The optoelectric applications, light emitters and photovoltaics, with organometallic halide perovskite materials have been decided by dynamics of charge carriers in grains on the polycrystalline thin films. Especially, polar solvent vapour recrystallizes perovskites and changes their grain sizes. In this paper, various polar solvents were evaluated with density functional theory calculation. And a stociometric treatment with these solvents which enhanced photoluminescence intensity was established. The properties of solvents which caused dramatic photoluminescence enhancement and quantum confinement effect were discussed. Comment: 11 pages including supplementary information, 4 figures in main paper
