Abstract
PbI2(DMSO) complex powder, which is essential to fabricate efficient metal halide perovskite solar cells (MHP SCs), was synthesized by liquid phase solvent extraction process irrespective of reaction volume scale. The isopropanol (IPA) solvent could selectively extract the DMSO from PbI2(DMSO)2 powder during extraction process so that compositionally uniform PbI2(DMSO) powder could be obtained in a large scale process, whereas the vacuum drying process could not produce uniform PbI2(DMSO) powder. Due to the compositional uniformity of PbI2(DMSO) powders prepared by solvent extraction process, the MHP SCs could be fabricated very reproducibly.
