Traditional solar cells harvest only a narrow sliver of the electromagnetic energy pouring down onto Earth, and that's one of the reasons it's been so challenging to get solar efficiency beyond 20-30 ...

Japan is pushing solar hydrogen into a new phase by teaching its materials to drink in colors of sunlight that used to go to ...

Researchers developed a solar collector with a dielectric Bragg mirror, optimizing energy conversion by separating sunlight ...

Researchers have created a dye-sensitized photocatalyst that captures long-wavelength visible light to double solar hydrogen production efficiency.

Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). Different colors have different energies, and no single semiconductor has a ...

Solar cells are one of the most important technologies in the transition to renewable energy, but there’s still plenty of room for improvement. Researchers at New York University (NYU) Tandon have now ...

(Nanowerk News) The sunlight received by Earth is a mixed bag of wavelengths ranging from ultraviolet to visible to infrared. Each wavelength carries inherent energy that, if effectively harnessed, ...

This work, which verifies one of the predictions of Einstein's General Relativity, is to be published in the journal Astronomy & Astrophysics. The General Theory of Relativity, published by Albert ...

Solar manufacturers are pushing the limits of solar efficiency. CNET explains what you need to pay attention to if you're shopping for residential solar panels. A major solar panel manufacturer says ...
