Ruddlesden-Popper defects act as a free surface: role in formation and photophysical properties of CsPbI3

Weilun Li, Qimu Yuan, Yinan Chen +5

The perovskite semiconductor, CsPbI3, holds excellent promise for solar cell applications due to its suitable bandgap. However, achieving phase-stable CsPbI3 solar cells with high…

Roadmap on Photovoltaic Absorber Materials for Sustainable Energy Conversion

James C. Blakesley, Ruy S. Bonilla, Marina Freitag +83

Photovoltaics (PVs) are a critical technology for curbing growing levels of anthropogenic greenhouse gas emissions, and meeting increases in future demand for low-carbon electricit…

Optical absorption spectra of metal oxides from time-dependent density functional theory and many-body perturbation theory based on optimally-tuned hybrid functionals

Guy Ohad, Stephen E. Gant, Dahvyd Wing +6

Using both time-dependent density functional theory (TDDFT) and the ``single-shot" plus Bethe-Salpeter equation (-BSE) approach, we compute optical band gaps and optical a…

An Optimally-Tuned Starting Point for Single-Shot Calculations of Solids

Stephen E. Gant, Jonah B. Haber, Marina R. Filip +5

The dependence of ab initio many-body perturbation theory within the approximation on the eigensystem used in calculating quasiparticle corrections limits this method's predic…

Hot electron cooling in InSb probed by ultrafast time-resolved terahertz cyclotron resonance

Chelsea Q. Xia, Maurizio Monti, Jessica L. Boland +4

Measuring terahertz (THz) conductivity on an ultrafast time scale is an excellent way to observe charge-carrier dynamics in semiconductors as a function of time after photoexcitati…

Phonon Screening of Excitons in Semiconductors: Halide Perovskites and Beyond

Marina R. Filip, Jonah B. Haber, Jeffrey B. Neaton

The ab initio Bethe-Salpeter equation (BSE) approach, an established method for the study of excitons in materials, is typically solved in a limit where only static screening from…
