Title: Electrochemical impedance analysis of perovskite–electrolyte interfaces

Journal Article · · ChemComm
DOI: https://doi.org/10.1039/C6CC10315D · OSTI ID:1345114

Here, the flat band potentials and carrier densities of spin coated and sprayed MAPbI3, FA0.85Cs0.15PbI3, and MAPbBr3 perovskite films were determined using the Mott-Schottky relation. The films developed a space charge layer and exhibited p-type conduction with carrier concentration ~ 1016 cm-3 for spin coated films. Electrochemical impedance spectra showed typical space charge impedance at frequencies > 1 kHz with increasing capacitance < 1 kHz owing to an ion diffusion component.
