The dynamics of internal electric field screening in hybrid perovskite solar cells probed using electroabsorption
Davide Moia, Ilario Gelmetti, Philip Calado +7
Electric fields arising from the distribution of charge in metal halide perovskite solar cells are critical for understanding the many weird and wonderful optoelectronic properties…
Driftfusion: An open source code for simulating ordered semiconductor devices with mixed ionic-electronic conducting materials in one-dimension
Philip Calado, Ilario Gelmetti, Benjamin Hilton +3
The recent emergence of lead-halide perovskites as active layer materials for thin film semiconductor devices including solar cells, light emitting diodes, and memristors has motiv…
Is it possible for a perovskite p-n homojunction to persist in the presence of mobile ionic charge?
Philip Calado, Piers RF Barnes
Recently Cui et al. reported on the fabrication a p-n homojunction perovskite solar cell (PSC) using stoichiometric control of sequentially-deposited perovskite layers. The authors…
Ionic-to-electronic current amplification in hybrid perovskite solar cells: ionically gated transistor-interface circuit model explains hysteresis and impedance of mixed conducting devices
Davide Moia, Ilario Gelmetti, Phil Calado +9
Mobile ions in hybrid perovskite semiconductors introduce a new degree of freedom to electronic devices suggesting applications beyond photovoltaics. An intuitive device model desc…
