Giant Huang-Rhys Factor for Electron Capture by the Iodine Interstitial in Perovskite Solar Cells

Lucy D. Whalley, Puck van Gerwen, Jarvist M. Frost +3

Improvement in the optoelectronic performance of halide perovskite semiconductors requires the identification and suppression of non-radiative carrier trapping processes. The iodin…

Delocalised kinetic Monte Carlo for simulating delocalisation-enhanced charge and exciton transport in disordered materials

Daniel Balzer, Thijs J. A. M. Smolders, David Blyth +2

Charge transport is well understood in both highly ordered materials (band conduction) or highly disordered ones (hopping conduction). In moderately disordered materials -- includi…

Quick-start guide for first-principles modelling of point defects in crystalline materials

Sunghyun Kim, Samantha N. Hood, Ji-Sang Park +2

Defects influence the properties and functionality of all crystalline materials. For instance, point defects participate in electronic (e.g. carrier generation and recombination) a…

Anharmonic Lattice Relaxation during Non-radiative Carrier Capture

Sunghyun Kim, Samantha N. Hood, Aron Walsh

Lattice vibrations of point defects are essential for understanding non-radiative electron and hole capture in semiconductors as they govern properties including persistent photoco…

Open-Circuit Voltage Deficit in Cu2ZnSnS4 Solar Cells by Interface Band Gap Narrowing

Ji-Sang Park, Sunghyun Kim, Samantha N. Hood +1

There is evidence that interface recombination in Cu2ZnSnS4 solar cells contributes to the open-circuit voltage deficit. Our hybrid density functional theory calculations suggest t…

Lone-pair effect on carrier capture in CuZnSnS solar cells

Sunghyun Kim, Ji-Sang Park, Samantha N. Hood +1

The performance of kesterite thin-film solar cells is limited by a low open-circuit voltage due to defect-mediated electron-hole recombination. We calculate the non-radiative carri…

Entropy and disorder enable charge separation in organic solar cells

Samantha N. Hood, Ivan Kassal

Although organic heterojunctions can separate charges with near-unity efficiency and on a sub-picosecond timescale, the full details of the charge-separation process remain unclear…

Squeezed-light-enhanced atom interferometry below the standard quantum limit

Stuart S. Szigeti, Behnam Tonekaboni, Wing Yung S. Lau +2

We investigate the prospect of enhancing the phase sensitivity of atom interferometers in the Mach-Zehnder configuration with squeezed light. Ultimately, this enhancement is achiev…
