An Investigation into the Effect of Mobile Ions on the Steady State Performance of Perovskite Solar Cells
Matthew V. Cowley, Kjeld O. Jensen, Matthew J. Wolf +2
In perovskite solar cells, the interplay between mobile ions and photo-excited charge carriers is complex,with recent studies suggesting mobile ions can be either beneficial or det…
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…
Quantifying polaronic effects on charge-carrier scattering and mobility in lead--halide perovskites
Matthew J. Wolf, Lewis A. D. Irvine, Alison B. Walker
The formation of polarons due to the interaction between charge carriers and the crystal lattice has been proposed to have wide-ranging effects on charge carrier dynamics in lead--…
