Next-gen solar collection materialsPosted: August 20, 2008
Here is a great description of a new material that will collect infrared radiation and convert it to electricity:
“The material, composed of tiny gold antennas set in polyethylene plastic is tuned to gather 80 percent of energy from infrared rays in its production version, and can gather energy from the sun, earth, or even your PC’s warmth. The antennas can be tuned to different parts of the infrared spectrum, and the thin material can be sandwiched together to cover the full desired range.”
This sounds great! 80% efficiency is extraordinary. Here is a material that draws heat energy from its surroundings and creates electricity. Sounds a bit like a reverse of the earlier post on electrocaloric materials, doesn’t it?
