Developed under the €3m ($2.4m) ProMEThEUS project, part of the European Commission's FP7 initiative, the material meets three key criteria for solar power generation: it can absorb radiation, is able to withstand ultra-high temperatures, and can efficiently release electrons.

"Solar radiation is the largest energy source we have on Earth. Its more efficient and diffused exploitation means a higher energy availability with a minimal contribution to CO formation," says project co-ordinator Daniele Trucchi.
