Solar water splitting is one of the most direct ways to produce green hydrogen using sunlight. However, most photocatalysts and photoelectrodes absorb only a limited portion of solar radiation, mainly ...

Though the sun produces more energy than we would ever need on Earth, current solar harvesting technologies are limited, and they don’t capture as much sunlight as they could. Now, a team of ...

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 ...
