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 an individual carbon nanotube. The tube was essentially a rolled-up sheet of graphene, and while the inner workings would take days to explain, the gist of it is this:
"The nanotube may be a nearly ideal photovoltaic cell because it allowed electrons to create more electrons by utilizing the spare energy from the light."
So, solar-powered F-350 trucks are now a possibility for next year, right?
