“To know yet to think that one does not know is best; Not to know yet to think that one knows will lead to difficulty.” Lao Tzu, philosopher (6th century BCE).

Graphene solar cells
Whilst still less than 10% efficient a team at The University of Florida has produced higher efficient graphene solar cells. The group was able to achieve an impressive 8.6 percent efficiency device by chemically doping, the graphene with trifluoromethanesulfonyl-amide. Their results are published in the online edition of Nano Letters.
