Abstract

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.
