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.
