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 ...

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 ...

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

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, ...

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 ...
