Revealing Polar Walls in CsPbBr3: Herringbone Structure and Formation Pathway
Weilun Li, Qimu Yuan, Michael B. Johnston +1
Domain walls in ferroic materials can host nanoscale functionalities absent from the periodic crystal, offering new opportunities to control electronic transport and polarization i…
Discovery of Ferroelectric Twin Boundaries in a Photoactive Halide Perovskite
Weilun Li, Qimu Yuan, Michael B. Johnston +1
Halide perovskites have emerged as promising materials for next-generation photovoltaics, laser sources and X-ray detectors. There is intense debate as to whether some photoactive…
Deriving a comprehensive dataset of optical constants for metal halide perovskites
Akash Dasgupta, Shuaifeng Hu, Seongrok Seo +5
Accurate optical constants are essential for modelling light propagation, absorption, and ultimately photovoltaic performance in state of the art perovskite solar cells and is espe…
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…
