Deposition and characterisation of perovskite thin films

Gregory, C

Abstract

The work presented in this thesis investigates the synthesis, depo-
sition and characterisation of halide doped perovskite thin films.
Films of methylammonium lead iodide CH3NH3PbI3 were doped
with Cl and Br ions to investigate the intrinsic differences of these
perovskites. As a result of doping, photoluminescence (PL) spectra
confirmed optoelectronic influence evidenced by changes in bang
gap energy. Bromine treated perovskites exhibited greater stability
throughout this study while Cl treated samples exhibited improved
morphology. A detailed analysis comprising of scanning electron mi-
croscopy and bulk/surface elemental compositional techniques con-
firmed morphological improvement due to the presence of Cl ions
despite being undetected using surface sensitive techniques.
