"Ultrablack Nanoneedles Show 99.5% Light Absorption Potential for Solar Towers"

Researchers at EHU have demonstrated that ultrablack nanoneedles can achieve 99.5% light absorption, potentially revolutionizing concentrated solar power technology and thermal energy storage.

• The study conducted by EHU researchers revealed that ultrablack nanoneedles made from copper cobaltate exhibit an impressive 99.5% absorption (electromagnetic radiation) capacity, significantly enhancing solar energy collection.
• This breakthrough in nanotechnology could improve the efficiency of concentrated solar power systems, which are increasingly viewed as a viable alternative to traditional photovoltaics for thermal energy storage.
• The research indicates that integrating ultrablack nanoneedles with existing solar technologies may reduce costs and complexity, positioning them as a competitive option in the renewable energy landscape.
