Abstract

Perovskites have quickly become globally renowned for their extremely attractive electronic and optical characteristics. However, a clear relationship between the composition and photoelectronic properties of perovskites is still not well understood, developing this understanding is imperative to designing perovskite devices tailored to suit the needs of the application. In this study we characterize chlorine-doped MAPbI thin films produced by aerosol assisted chemical vapor deposition and compare the composition of the sample series via a comprehensive set of spectroscopy techniques including: Raman, photoluminescence, X-ray photoelectron and ultrafast transient absorption spectroscopy. We discuss the spectral properties revealed and relate our findings to the mechanisms attributed to the impressive optoelectronic properties exhibited by the perovskite structure.
