Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, ...

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

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

Researchers at the University of Ottawa have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called achiral plasmonic ...

Researchers have developed a new method for light and matter interaction, paving the way for the production of ultrathin silicon solar cells. The University of California, Irvine (UC Irvine) team's ...

Researchers are making progress on the design of a solar battery made from an abundant, non-toxic and easily synthesized material composed of 2D carbon nitride. The collaborative effort between the ...

A research team has enhanced the titanium oxo clusters’ capacity to absorb solar energy. Their work demonstrates a successful method for modifying the behaviors of these clusters in terms of light ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

It's not convincing to me either. Munroe is correct about etendue, of course, so that the best a lens can do is equivalent to having the object of focus be surrounded by the light source. But that ...

Researchers have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called achiral plasmonic metasurfaces, can absorb light ...
