Researchers in Hong Kong Hong Kong fabricated a thermochromic bifacial photovoltaic glazing system prototype that passively regulates solar heat gain while harvesting energy from both sides.

Solar water splitting is one of the most direct ways to produce green hydrogen using sunlight. However, most photocatalysts ...

The system enables measurements under controlled irradiance, spectrum, and temperature conditions. It can combine 0.4% spatial irradiance uniformity, 500 ms illumination pulses, and dynamic I-V ...

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn’t capture as much as it could. Now, in ACS Applied Materials & Interfaces, researchers report that gold ...

As the global push for renewable energy accelerates, capturing the full spectrum of solar energy remains a significant challenge. Photovoltaic (PV ...

A salt called guanidinium thiocyanate can improve the efficiency and stability of perovskite solar cells, a new class of semiconductor that could make solar power cheaper and more powerful, according ...

Gold nanosphere supraballs absorb a bout 90% of sunlight across all wavelengths, nearly doubling energy capture and boosting power output 2.4x when applied to solar cells. This supraball (left) is ...
