Nanomaterial Promises to Reduce Shutdowns of Concentrating Solar Power Plants

Researchers at the University of California at San Diego have developed a composite nanomaterial that can convert 90 percent of the sunlight it captures into heat , making it an ideal candidate for solar absorption at concentrating solar power (CSP) plants. "We wanted to create a material that absorbs sunlight [and] doesn't let any of it escape. We want the black hole of sunlight," said Sungho Jin, a professor at UC San Diego, in a press release. The hybrid material, which is described in the journal Nano Energy , combines copper oxide nanowires with cobalt oxide nanoparticles to create a multi-scale surface for the material with dimensions ranging from 10 nanometers to micrometers. This multi-scale surface gives the material its extraordinary efficiency at trapping and absorbing light. Previous research has proposed the use of nanowires for concentrating the sun’s rays in...
