Graphene, wonder-stuff extraordinaire, has been looking to revolutionise all sorts of things from chips to lightning fast internet. Next up is night vision and solar power.
Boffins from MIT have discovered that the ultra-thin carbon layers that form graphene will generate electricity straight from sunlight. Previously thought to be a standard photovoltaic effect, it now seems that a change in temperature generates the electricity. Use of graphene could lead to more efficient solar cells and even better night-vision technology, thanks to its ability to use infrared light as well as ordinary sun light -- no one will be safe from your gaze during your midnight paintball firefights.
