Black diamond is obtained by a controlled nanoscale periodic texturing of cvd diamond surface able to drastically modify the interaction with solar radiation from optical transparency up to solar. Dr fox is developing special electrodes for the converters using nanoparticles of industrial diamond powder which is low cost and readily available.

In any case the most immediate application of black diamond especially in its high defect density but large area low cost polycrystalline form is as a competitive high temperature radiation absorber for solar thermodynamic conversion due to a solar absorptance larger than 90 and high thermal resistance.

By alessandro bellucci paolo calvani marco girolami. A european research team within the european commission s fp7 framework are leading the prome3the2us2 project developing the black diamond as a breakthrough concept which is expected to change the future of solar technology it has the potential to exceed 50 per cent efficiency in solar.
