Scientists have achieved high efficiency in silicon solar cells with the help of precision-engineered surfaces. New designs of antireflective coatings for silicon solar cells, based on single-layer ...

Owing to the wave nature of light there are many ways that such ... microwave radiation beams off each other, creating a time reflection. Although the popular reporting talks about ‘turning ...

The coating works across the visible and near-infrared spectrum (500 to 1200 nm) and is effective even when the sunlight hits at steep angles. It reflects as little as 2 per cent of incoming light at ...
