Starting materials: CsI, PbI2, dimethyl sulfoxide

Product: CsPbI3 film

Description: Equimolar amounts of CsI and PbI2 were dissolved in dimethyl sulfoxide at 0.6M, in a nitrogen-filled glovebox. Films were spin-coated at 2000rpm and annealed at 100 degrees C for 5 minutes in the glovebox.

Method: Optical absorption

Description: Transmittance and reflectance spectra were collected with a Varian Cary 300 UV-Vis spectrophotometer with an internally coupled integrating sphere.
