Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Long-lived polarization memory in the electronic states of lead-halide perovskites from local structural dynamics

Nature Communications, 2018
Anharmonic ultrafast structural dynamics are expected in lead halide perovskites due to their soft nature. Here Rivett et al. show that these dynamics lead to picosecond-long polarization anisotropy of photo-carriers in several halide perovskites, orders

Topological polarons in halide perovskites

Proceedings of the National Academy of Sciences
Halide perovskites emerged as a revolutionary family of high-quality semiconductors for solar energy harvesting and energy-efficient lighting. There is mounting evidence that the exceptional optoelectronic properties of these materials could stem from unconventional electron–phonon couplings, and it has been suggested that the formation of polarons and

Directional Flow of Confined Polaritons in CrSBr

Advanced Materials, EarlyView.
CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Photophysics of Lead-Halide Perovskite

, 2018
The Sun provides Earth with a greenhouse gas free source of energy that exceeds the annual energy consumption by orders of magnitude. Current solar cell technology limits the percentage of harvested solar energy that can be used to generate electricity; this is why new concepts and materials for photovoltaics are being explored.
