SEM of Multisurface Material (IMAGE) University of California - San Diego Caption Engineers at UC San Diego have developed a nanoparticle-based material for concentrating solar power plants that converts 90% of captured sunlight to heat. With particle sizes ranging from 10 nanometers to 10 micrometers, the multiscale structure traps and absorbs light more efficiently and at temperatures greater than 700 degrees Celsius.
