Accurate optical properties from first principles: a Quasiparticle Self consistent GW plus Bethe-Salpeter Equation approach
Brian Cunningham, Pooya Azarhoosh, Dimitar Pashov +2
We present an approach to calculate the optical absorption spectra that combines the quasiparticle self-consistent GW method [Phys. Rev. B, 76 165106 (2007)] for the electronic str…
Dynamic Symmetry Breaking and Spin Splitting in Metal Halide Perovskites
Scott McKechnie, Jarvist M. Frost, Dimitar Pashov +3
Metal halide perovskites exhibit a materials physics that is distinct from traditional inorganic and organic semiconductors. While materials such as CH3NH3PbI3 are non-magnetic, th…
A photon ratchet route to high-efficiency hybrid halide perovskite intermediate band solar cells
Jarvist M. Frost, Pooya Azarhoosh, Scott McKechnie +2
The spin-split indirect bandgap in hybrid-halide perovskites provides a momentum-space realisation of a photon-ratchet intermediate band. Excited electrons thermalise to recombinat…
Relativistic origin of slow electron-hole recombination in hybrid halide perovskite solar cells
Pooya Azarhoosh, Jarvist M. Frost, Scott McKechnie +2
The hybrid perovskite CH3NH3PbI3 (MAPI) exhibits long minority-carrier lifetimes and diffusion lengths. We show that slow recombination originates from a spin-split indirect-gap. L…
