Astronomers using the Daniel K. Inouye Solar Telescope (DKIST) have captured a solar flare that defies all expectations, shaking the foundations of solar physics. This new discovery, reported in two ...

At any given moment, 89,000 terawatts of solar power hits the Earth’s surface. While significant advancements have been made in harvesting this power, existing technologies do not capture the full ...

The ASTM G173 Standard Spectral Distribution of Sunlight represents a standard, reference solar spectrum that is used for solar photovoltaics testing and calibration purposes. It was defined in the ...

Researchers led by a team at Spain's Technical University of Madrid (ISOM-UPM) have demonstrated a broadband antireflective coating (ARC) for gallium arsenide-based solar cells. The nanostructured ...

Sunlight carries more energy than most solar devices can catch. That gap matters as heat waves grow worse. It also matters as grids strain under rising demand. A team working at the KU R&D Center at ...
