Tasks Dissolve graphite powders in equimolar C6H6/C6F6 mixed
solvent, followed by sonication and centrifuging. Take supernatant liquid as graphene solution. Identify quality,
size by Raman and TEM/AFM. Determine graphene concentration by UV spectrum.
Transfer and blend graphene with P3HT in p-xylene by equal mass.
Make P3HT/F8BT/G solutions in p-xylene with different polymer and graphene concentration.
Make solar cell devices (Glass+ITO+PEDOT:PSS+P3HT/F8BT/G+LiF+Al)
Thermal treatment on polymer films and devices. Characterization: J-V test, EQE, absorption, thickness and XRD. Exploratory experiments and paper work on this project.
