Leave it to the Fighting Irish to take a stab at solving the world's energy woes. Notre Dame researchers have successfully developed solar cells that can be easily painted on to any conductive surface. Imagine, for a moment, applying this solution to your home rather than attaching solar panels to the roof. The paint mixture incorporates quantum dots of titanium dioxide, which is then coated with either cadmium sulfide or cadmium selenide, and is then suspended in mixture of water and alcohol to create a spreadable compound that's capable of generating electricity. While its efficiency isn't currently much to crow home about -- which hovers around one-percent -- scientists are now actively pursuing ways to improve this aspect while making a more stable compound. Most importantly, the paint can be made cheaply and in large quantities, which suggests that even if efficiency remains in the doldrums, it may be a very worthwhile pursuit. Touchdown Jesus is already watching the video after the break.
