If solar cells could generate higher voltages when sunlight falls on them, they'd produce more electrical power more efficiently.
Scientists at Berkeley Lab find nanoparticle size is readily controlled to make stronger aluminum alloys.
Graphene, a sheet of carbon only a single atom thick, was an object of theoretical speculation long before it was actually made.
Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps).
Graphene is the two-dimensional crystalline form of carbon, whose extraordinary electron mobility and other unique features hold great promise for nanoscale electronics and photonics. But there's a catch: graphene has no bandgap.
Because they are riddled with defects, bulk crystalline materials never achieve their ideal strength; nanocrystals, on the other hand, are so small thereâ€™s no room for defects.
