Abstract

Herein, doping of methylammonium lead iodide perovskite thin films with bromine ions is successfully performed for the first time using the aerosol-assisted chemical vapour deposition process. Depending on the doping levels, photoluminescence spectra are shifted relative to their bandgap values. Detailed analysis of scanning electron microscope images showed that increasing the bromine levels linearly increased the grain sizes. The unchanged amount of detected lead provided evidence for the controlled processing conditions. Both bulk and surface compositional techniques confirmed the deposition of marginally iodine rich perovskite thin films.
