A single gold nanoparticle tends to absorb within a narrow band. Much of its strongest response sits in visible wavelengths.

Though the sun produces more energy than we would ever need on Earth, current ...

Researchers have engineered tiny gold nanospheres that can soak up almost the entire spectrum of solar energy, promising a ...

Perovskite-silicon hybrid solar cells, launching in 2026, promise 34% higher efficiency than traditional panels. This ...

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 ...

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 ...

Consumer interest in rooftop solar is higher than ever. The most recent numbers from Pew Research show 89% of U.S. adults favor the expanded use of solar power, while only 9% oppose. Historically, ...
