Abstract:
Carbon nanotubes--tiny strawlike cylinders of pure carbon--have interesting electrical properties. Indeed, they have already been used to manufacture tiny transistors and nanowires. Now scientists say the minuscule cylinders may one day find their way into solar cells. Researchers report in the latest issue of the journal Angewandte Chemie International Edition that they have succeeded in tweaking the tubes so that they supply electrons when exposed to visible light.
