Scientists raise solar absorber efficiency using nanotechnology

Reported from CSPPLAZA: Researchers at the United Arab Emirates’ Masdar Institute and the Massachusetts Institute of Technology (MIT) have jointly developed a new high-performance solar absorber which could lower the cost of CSP generation, the Masdar Institute said in a statement.

The new absorber uses an ultrathin nano-composite film made of silver and silica, topped with silver nanoparticles, to absorb nearly 100% of sunlight energy from the ultraviolet and visible portions of the solar spectrum, the Institute said.

Advanced microscopy showed traditional solar absorbers were filled with tiny nano-particles of each composite element and large nano-particles on the top surface. Further studies showed the top layers of nano-particles make absorbers more efficient and the scientists used this knowledge to build the nano-composite film.

The researchers worked with engineers at the 100 MW Shams 1 parabolic trough plant in Abu Dhabi to develop a desert-specific product.

“The technology we have demonstrated is particularly attractive for hot-arid regions, such as Abu Dhabi, with potential applications in waste water treatment, seawater desalination, and power generation,” Professor Gang Chen of MIT, said.
