The quest to builder a better, cheaper solar cell continues on, as researchers at the New Jersey Institute of Technology have developed a new type of solar cell that can be printed or painted onto flexible plastic sheets. Unlike traditional silicon cells, the print-on cells are composed of carbon nanotubes and buckyballs, which results in substantially cheaper manufacturing costs and greater efficiency, since apparently carbon nanotubes are terrific conductors. The scientists seem pretty pumped about the potential for their tech,
