Researchers at the Karlsruhe Institute of Technology in Germany, working in the new field of transformation optics, have created an invisibility cloak that could lead to more efficient solar cells. The researchers have been able to manipulate a beam of light — a red light at a wavelength of 700 nanometers — to actually make something visually disappear. This isn’t all about making things disappear, however, the new technology’s biggest promise is in the refraction of light — which will help scientists concentrate solar rays into more efficient solar energy technology.
