Closing in on a carbon-based solar cell

Graphene space-filling model

To make large sheets of carbon available for light collection, Indiana University Bloomington chemists have devised an unusual solution -- attach what amounts to a 3-D bramble patch to each side of the carbon sheet. Using that method, the scientists say they were able to dissolve sheets containing as many as 168 carbon atoms, a first. The scientists' report, online today (April 9), will appear in a future issue of Nano Letters, an American Chemical Society journal. Full Story >>
