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 ...

A new solar breakthrough may overcome a long-standing efficiency barrier. Researchers used a “spin-flip” metal complex to capture and multiply energy from sunlight through singlet fission. The result ...

Scientists led by Linköping University and Cornell University have proposed a new technique to recycle perovskite solar cells made on glass substrates using a water-based solution. The novel approach ...

It was found that the onion-dye film performed best, blocking 99.9% of UV light with a wavelength of up to 400 nanometers. That said, it still allowed over 80% of visible light transmission at longer ...

Scientists in Spain have developed an amorphous-silicon solar cell that could be used in both transparent photovoltaics and tandem applications. The device reportedly achieves notable efficiency ...
