Spin-on Carbon–based Electrodes for Thin Film Photovoltaics

 

Graphene Transparent Electrode
Low-cost solar energy conduction
Conventional photovoltaics use a transparent layer of Indium Tin Oxide (ITO) to conduct energy. ITO film is expensive due to the high cost of the current ITO vacuum fabrication method and the high cost of Indium materials.This project seeks to replace the ITO in solar cells with a lower-cost layer of grapheme, a sort of “atomic chicken wire” crafted from bonded carbon atoms, applied to the photovoltaic via a spin-on process from solution. Project members are currently engaged in optimizing preliminary methods of fabricating graphene.

Accomplishments:
  • Developed a method to exfoliate sheets of graphene from graphite flakes.
  • Developed preliminary methods to fabricate graphene films from solution.
