Are you ready for windows that can double as solar panels? It could happen sometime in the near future thanks to work done by scientists at Los Alamos National Laboratory and University of Milano-Bicocca (UNIMIB), Italy. They are using quantum dots to harvest the energy from sunlight over a large […]
Windows That Act As Solar Panels
Wait…what? Gold is shiny. How could you add gold to something to make it less reflective? Scientists at University of California Irvine stumbled upon a method to remove glare on optics, solar panels or even your phone’s screen. While working on a transparent film, the students found their samples appeared to […]
