Quantitative chemical analysis of perovskite deposition using spin coating

Research output: Contribution to journalArticle

Lead and halide ion compositions of spin coated organo-lead halide perovskite films have been quantified using ion chromatography (IC) and atomic absorption spectroscopy (AAS) using perovskite films manufactured by 5 different researchers (3 replicates per treatment) to monitor variability between researchers and individual researcher reproducibility. Planar and mesoporous TiO2-coated glass substrates have been studied along with tribromide (CH3NH3PbBr3), triiodide (CH3NH3PbI3) and mixed halide (CH3NH3PbI3−xClx) perovskite films. The data show low yields of spin coated perovskite material (ca. 1%) and preferential deposition of I− over Cl− in mixed halide films.
