Abstract :
Graphene nanosheets (GN) have been synthesized by solution phase exfoliation of graphite in organic solvents. Subsequently, low concentration of GN (2 wt%) uniformly distributed within the P3HT and P3HT-PCBM photo active layers are shown to enhance the crystallinity of the conjugated polymer.
