Femtosecond Stimulated Raman Spectroscopy Helps Study How Plastic Solar Panels Work

Scientists don't fully understand how 'plastic' solar panels work, which complicates the improvement of their cost efficiency, thereby blocking the wider use of the technology. However, researchers at the University of Montreal, the Science and Technology Facilities Council, Imperial College London and the University of Cyprus have determined how light beams excite the chemicals in solar panels, enabling them to produce charge.

Ultraviolet Photons Emitted by the Sun May Cause Water Molecules to Break Apart

Water is thought to be embedded in the moon’s rocks or, if cold enough, “stuck” on their surfaces. It’s predominantly found at the poles. But scientists probably won’t find it intact on the sunlit side.

Novel Method to Design, Simulate and Optimize Photonic Crystal Nanocavities

Just as electronic circuits work with electrical charges, optical circuits process pulses of light, which gives them a distinct advantage in terms of speed. Optical technologies are therefore the object of intense research, aiming to develop novel optical devices that can control the flow of light at the nanometer scale.

Researchers Create Silicon Light-Trapping Nanostructure

Physicists at the University of Rochester have created a silicon nanocavity that allows light to be trapped longer than in other similarly-sized optical cavities. An innovative design approach, which mimics evolutionary biology, allowed them to achieve a 10-fold improvement on the performance of previous nano cavities.
