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

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 ...

A new single molecule can absorb the full spectrum of sunlight and turn it into valuable hydrogen. Freeing hydrogen to use as fuel is a major science holy grail in the 21st century. Costly, ...

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 ...

Perovskite-silicon hybrid solar cells, launching in 2026, promise 34% higher efficiency than traditional panels. This breakthrough combines advanced materials science and physics to accelerate global ...

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 ...

The ASTM G173 Standard Spectral Distribution of Sunlight represents a standard, reference solar spectrum that is used for solar photovoltaics testing and calibration purposes. It was defined in the ...

Solar power is set for a boost with the help of a material that can soak up energy from almost all of the Sun’s spectrum. It should allow solar cells to jump in efficiency from today’s best of 30 per ...
