More is Different: Mobile Ions Improve the Design Tolerances of Perovskite Solar Cells
Lucy J. F. Hart, Fraser J. Angus, Yin Li +5
Many recent advances in metal halide perovskite solar cell (PSC) performance are attributed to surface treatments which passivate interfacial trap states, minimise charge recombina…
Generalised Framework for Controlling and Understanding Ion Dynamics with Passivated Lead Halide Perovskites
Tomi K. Baikie, Philip Calado, Krzysztof Galkowski +11
Metal halide perovskite solar cells have gained widespread attention due to their high efficiency and high defect tolerance. The absorbing perovskite layer is as a mixed electron-i…
The Validity Window of Space-Charge-Limited Current Measurements of Metal Halide Perovskite Devices
William R. Fisher, Philip Calado, Jason A. Röhr +5
Space-charge-limited current (SCLC) measurements are used to estimate charge carrier mobilities and electronic trap densities of semiconductors by analysing the current density-vol…
Identifying dominant recombination mechanisms in perovskite solar cells by measuring the transient ideality factor
Phil Calado, Dan Burkitt, Jizhong Yao +7
The ideality factor determined by measuring the open circuit voltage (VOC) as function of light intensity is often used as a means to identify the dominant recombination mechanism…
Influence of water intercalation and hydration on chemical decomposition and ion transport in methylammonium lead halide perovskites
Un-Gi Jong, Chol-Jun Yu, Gum-Chol Ri +4
The use of methylammonium (MA) lead halide perovskites \ce{CH3NH3PbX3} (X=I, Br, Cl) in perovskite solar cells (PSCs) has made great progress in performance efficiency during recen…
Dynamic disorder, phonon lifetimes, and the assignment of modes to the vibrational spectra of methylammonium lead halide perovskites
Aurélien M. A. Leguy, Alejandro R. Goñi, Jarvist M. Frost +11
We present Raman and terahertz absorbance spectra of methylammonium lead halide single crystals (MAPbX3, X = I, Br, Cl) at temperatures between 80 and 370 K. These results show goo…
Evidence for ion migration in hybrid perovskite solar cells with minimal hysteresis
Philip Calado, Andrew M. Telford, Daniel Bryant +4
Ionic migration has been proposed as a possible cause of photovoltaic current-voltage hysteresis in hybrid perovskite solar cells. However, a major objection to this hypothesis is…
Lattice dynamics and vibrational spectra of the orthorhombic, tetragonal and cubic phases of methylammonium lead iodide
Federico Brivio, Jarvist M. Frost, Jonathan M. Skelton +7
The hybrid halide perovskite CH3NH3PbI3 exhibits a complex structural behaviour, with successive transitions between orthorhombic, tetragonal and cubic polymorphs at ca. 165 K and…
