Acceptor Engineered Hole‐Transporting Materials for Inverted Perovskite Solar Cells

Solar RRL, Volume 10, Issue 17, 15 September 2026.
Dopant‐free dipolar hole‐transporting materials (HTMs) incorporating barbituric acid and rhodanine acceptors were synthesized and characterized for use in inverted perovskite solar cells. Of the two acceptors, barbituric acid‐based HTMs demonstrated effective defect passivation, achieving a power conversion efficiency of 19.94%.

On stellar activity cycle-related cosmic ray modulation effects in the astrosphere of Proxima Centauri

Journal of Space Weather and Space Climate
In the heliosphere, solar cycle-related changes in galactic cosmic ray (GCR) intensities have long been known to arise as a direct consequence of solar cyclic changes in, for example, the heliospheric magnetic field and the solar tilt angle.

Solar Modulation of Low-energy Cosmic-Ray Nitrogen and Its Comparison with Oxygen

The Astrophysical Journal
The heliospheric environment is very complex and filled with diverse high-energy particles from various origins, and among these particles, cosmic rays (CRs), including anomalous and Galactic components (ACRs and GCRs), are unique as they originate from ...

Fifty years of studying the GCR intensity during inversion of the heliospheric magnetic fields. II. HMF inversion on the inner heliospheric boundary

Solar-Terrestrial Physics
Phenomena in the outer layer of the solar atmosphere, the heliosphere, including the supersonic solar wind, the heliospheric magnetic field (HMF) carried by it, and cosmic rays propagating in the heliosphere are important for many processes occurring in ...

Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Can Solar Cyclic Variability Mimic Extreme Solar Particle (Miyake) Events in Radiocarbon?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Rapid, strong enhancements in Δ14 ${{\Delta }}^{14}$C in the Earth's atmosphere, known as Miyake events, rarely occurred over the past millennia, pointing to major radiation storms affecting Earth. They are produced by extreme solar particle events (ESPEs) and are separated by an order‐of‐magnitude gap in the strength from directly observed ...
