A new nano-particle for concentrating solar power plants can absorb more than 90% of the sunlight it captures and convert it to heat, and withstand temperatures above 700°C, Science Daily reported earlier this month.
“We wanted to create a material that absorbs sunlight that doesn’t let any of it escape,” said Prof. Sungho Jin of UC San Diego. “We want the black hole of sunlight.”
The new material “features a ‘multiscale’ surface created by using particles of many sizes ranging from 10 nanometers to 10 micrometers,” Science Daily noted. “The multiscale structures can trap and absorb light, which contributes to the material’s high efficiency when operated at higher temperatures.”
