Using state-of-the-art equipment, researchers in the Thermophysical Properties of Materials group from the University of the Basque Country (EHU) have analyzed the capacity of ultra-black copper cobaltate nanoneedles to effectively absorb solar energy. They showed that the new nanoneedles have excellent thermal and optical properties and are particularly suited to absorbing energy. This will pave the way toward concentrated solar power in the field of renewable energies.
Ultra-black nanoneedles absorb 99.5% of light for future solar towers
