Inhomogeneous Defect Distribution in Mixed-Polytype Metal Halide Perovskites

Young Won Woo, Zhenzhu Li, Young-Kwang Jung +2

The competition between corner, edge and face-sharing octahedral networks is a cause of phase inhomogeneity in metal halide perovskite thin-films. Here we probe the charged iodine…

Band Versus Polaron: Charge Transport in Antimony Chalcogenides

Xinwei Wang, Alex M. Ganose, Seán R. Kavanagh +1

Antimony sulfide (Sb2S3) and selenide (Sb2Se3) are emerging earth-abundant absorbers for photovoltaic applications. Solar cell performance depends strongly on charge carrier transp…

Band gap opening from displacive instabilities in layered covalent-organic frameworks

Ju Huang, Matthias J. Golomb, Seán R. Kavanagh +3

Covalent organic frameworks (COFs) offer a high degree of chemical and structural flexibility. There is a large family of COFs built from 2D sheets that are stacked to form extende…

Impact of metastable defect structures on carrier recombination in solar cells

Seán R. Kavanagh, David O. Scanlon, Aron Walsh +1

The efficiency of a solar cell is often limited by electron-hole recombination mediated by defect states within the band gap of the photovoltaic (PV) semiconductor. The Shockley-Re…
