“In most materials, one absorbed photon generates one electron, but
in the case of graphene, we have seen that one absorbed photon is able
to produce many excited electrons, and therefore generate larger
electrical signals,” says Frank Koppens, group leader at ICFO.
This ability makes graphene extremely appealing for any technology
that requires the conversion of light into electricity, particularly
because it allows the development of light detectors with improved
efficiency, and should lead to solar cells that are able to capture light energy from all of the solar spectrum with lower loss.”
So basically, super-solar. I dig.
