Ferroelectric Materials for Solar Energy Conversion: Photoferroics Revisited
Keith T. Butler, Jarvist M. Frost, Aron Walsh
The application of ferroelectric materials (i.e. solids that exhibit spontaneous electric polarisation) in solar cells has a long and controversial history. This includes the first…
Molecular ferroelectric contributions to anomalous hysteresis in hybrid perovskite solar cells
Jarvist M. Frost, Keith T. Butler, Aron Walsh
We report a model describing the molecular orientation disorder in CH3NH3PbI3, solving a classical Hamiltonian parametrised with electronic structure calculations, with the nature…
Atomistic origins of high-performance in hybrid halide perovskite solar cells
Jarvist M. Frost, Keith T. Butler, Federico Brivio +3
The performance of organometallic perovskite solar cells has rapidly surpassed that of both conventional dye-sensitised and organic photovoltaics. High power conversion efficiency…
Electronic chemical potentials of porous metal-organic frameworks
Keith T. Butler, Christopher H. Hendon, Aron Walsh
The binding energy of an electron in a material is a fundamental characteristic, which determines a wealth of important chemical and physical properties. For metal-organic framewor…
Relativistic quasiparticle self-consistent electronic structure of hybrid halide perovskite photovoltaic absorbers
Federico Brivio, Keith T. Butler, Aron Walsh +1
Solar cells based on a light absorbing layer of the organometal halide perovskite CHNHPbI have recently reached 15% conversion efficiency, though how these materials wo…
