Graphene quantum dots dramatically improve the efficiency of organic solar cells

Graphene sheets have been shown to act as good acceptors when blended with conjugated polymers, but after blending, the photovoltaic characteristics of the polymers are considerably degraded. Scientists have now shown that the situation can be dramatically improved by blending polymers with graphene quantum dots instead of sheets.
