Tungsten, in particular, is a good metal for absorbing solar power, but this new laser treatment — which builds nanostructures on the surface of the metal — increases efficiency by 130% compared to untreated tungsten. The team has previously used a similar technology to make metals either hydrophilic or hydrophobic.
