Moth-inspired graphene becomes more light and heat absorbing

UK-based scientists from BAE Systems and the University of Surrey have discovered that patterned graphene sheets, inspired by moths’ eyes, could be used to capture light to produce energy or power sensors, and could also be used to develop “smart wallpaper” capable of powering Internet of Things applications.

The researchers claim that the newly developed material is the most light-absorbent substance for its weight developed to date, and drastically improves the efficiency of traditional graphene. They explain that graphene typically absorbs just 2.3% of incidental light; However, their new version of the material could collect as much as 90% more waste light and heat to produce more energy. The difference is a new technique which grows graphene around a textured metallic surface.
