Starting materials: TPI, PbI2, dimethylformamide (DMF)

Product: Tributyl(methyl)phosphonium lead iodide film

Description: PbI2 (0.5 mol) and TPI (0.5 mol) were both dissolved in DMF (1 mL). The resulting solution (30 μL) was dropped onto a glass surface. Spin-coating was performed at 5000 rpm for 30 seconds, then the film was annealed at 100°C for 5 minutes.

Method: UV-Vis Spectroscopy

Description: The absorbance spectrum of TPPbI3 films were recorded using UV-Vis spectroscopy, no information about equipment given.
