Chemically modified graphene oxides as a hole transport layer in organic solar cells†
Abstract
We demonstrate O2 plasma treated graphene oxides with a work function of 5.2 eV as a high performance hole transport layer in organic solar cells. The high transparency and high work function simultaneously increase short circuit current, threshold voltage and fill factor, resulting in a 30% increase in cell efficiency.
