Epitaxial Electrodeposition of Methylammonium Lead Iodide Perovskites
An
electrochemical/chemical route is introduced to deposit both
textured and epitaxial films of methylammonium lead iodide (MAPbI<sub>3</sub>) perovskites. The perovskite films are produced by chemical
conversion of lead dioxide films that have been electrodeposited as
either textured or epitaxial films onto [111]-textured Au and [100]
and [111] single-crystal Au substrates. The epitaxial relationships
for the MAPbI<sub>3</sub> films are MAPbI<sub>3</sub>(001)[010]∥PbO<sub>2</sub>(100)⟨001⟩ and MAPbI<sub>3</sub>(110)[111]∥PbO<sub>2</sub>(100)⟨001⟩ regardless of the Au substrate orientation,
because the in-plane order of the converted film is controlled by
the epitaxial PbO<sub>2</sub> precursor film. The textured and epitaxial
MAPbI<sub>3</sub> films both have trap densities lower than and photoluminescence
intensities higher than those of polycrystalline films produced by
spin coating
