Overscreening and Underscreening in Solid-Electrolyte Grain Boundary Space-Charge Layers
Jacob M. Dean, Samuel W. Coles, William R. Saunders +4
Polycrystalline solids can exhibit material properties that differ significantly from those of equivalent single-crystal samples, in part, because of a spontaneous redistribution o…

3D-to-2D Transition of Anion Mobility in CsPbBr under Pressure
Thijs J. A. M. Smolders, Alison B. Walker, Matthew J. Wolf
We study the effects of hydrostatic pressure in the range 0.0--2.0 GPa on anion mobility in the orthorhombic phase of CsPbBr. Using density functional theory and the c…

Deducing the key physical properties of a perovskite solar cell from its impedance response: insights from drift-diffusion modelling
Antonio Riquelme, Laurence J. Bennett, Nicola E. Courtier +5
Interpreting the impedance response of perovskite solar cells (PSC) is significantly more challenging than for most other photovoltaics. This is for a variety of reasons, of which…
