Presentation Transcript

  1. Synthesis of Solar Cell Materials, and Fabrication of Novel Polymer-Based Solar cells Yan Jin Prof. Vikram K. Kuppa

  2. Materials and Device Structure Donor: P3HT Accepter: F8BT

  3. Graphene • Graphene exfoliation form graphite • Identify graphene quality, size, thickness, and layers • Transfer graphene and blend with polymer

  4. 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.
