New Metamaterial Means More Efficient Solar Cells
ElectricSteve writes "Metamaterials are man-made substances designed to do some very weird things that natural materials don't. The path of a beam of light through a natural material like glass is predictable, but scientists from the California Institute of Technology have engineered an optical material that bends light in the wrong direction. This new negative-index metamaterial (NIM) could have several valuable uses including invisibility cloaking, superlensing (imaging nano-scale objects using visible light), and improved light collection in solar cells."
As usual with "SOLAR CELLS HERE TOMORROW!" stories, the actual important news in the story is buried around paragraph six.
This is not the first time such a material has been developed, but it is the first one that can handle light of any polarity, from any angle. It also works in the blue part of the visible spectrum, making it the first NIM to operate at visible frequencies.
Ah, thank you. As usual, a nice, modestly useful development of moderate interest to those who study materials engineering, and of essentially zero interest to anybody else. (Well, except for us science nerds, who shouldn't have to be sold the fluff, but it's what we get anyway.)
But since press releases attract more attention than journal articles, at least when they promise free power, you put FREE SOLAR ENERGY at the top and actual scientific research gets a paragraph somewhere in the middle.
