Development and application of a global magnetic field evolution model for the solar corona

open access: yes, 2009
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Application of a Grid-constrained U-shaped Neural Operator in Real-time Solar Corona Magnetic Field Extrapolation

open access: yesThe Astrophysical Journal Supplement Series
In this study, we propose a neural network framework, called the Grid-constrained U-shaped Neural Operator (GC-UNO), for real-time extrapolation of the coronal magnetic fields of active regions (ARs).

Lattice‐Matched 2D Template Enables Efficient Cesium Tin Halide Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Lattice‐matched 2D perovskite PEA2CsSn2I7 templates the out‐of‐plane growth of inorganic 3D γ‐CsSnI3 along the (110) plane, forming highly oriented 2D/3D tin halide perovskite heterostructures. With reduced trap states and mitigated δ‐phase impurities, the CsSnI3‐based solar cells achieve a power conversion efficiency of 15.27% and maintain stable ...

The Heliosphere Through the Solar Activity Cycle

open access: yes, 2006
Understanding how the Sun changes though its 11-year sunspot cycle and how these changes affect the vast space around the Sun the heliosphere has been one of the principal objectives of space research since the advent of the space age. This book presents

Two‐Dimensional Motions of Diffuse Auroral Patches Under Upstream Dynamic Pressure Enhancements of the Bow Shock

open access: yesGeophysical Research Letters
In this study, we identified 51 dayside diffuse auroral patches and examined their two‐dimensional evolutions by using the Time History of Events and Macroscale Interactions during Substorms probes and the ground‐based all‐sky imager at the South Pole ...

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

open access: yesAdvanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.
