You know what we love? Solar-powered gadgets, and carbon nanotubes. Oh, and Ivy League schools. Boffins from Cornell University are now looking to use the multifaceted carbon nanotube instead of silicon to develop efficient solar cells, and judging by the glacial pace at which solar cell efficiency is improving, we'd say the sector could use the boost. The researchers have already fabricated, tested and measured a simple solar cell (called a photodiode, just so you know) that was formed from
