Abstract

In this work, we focus on introducing an alternative approach to realize transparent graphene anodes. We report the use of very thin thermally evaporated gold (Au) nanoclusters with proper UVO treatments to facilitate efficient hole collection at graphene electrodes, which significantly benefits device performance while avoiding issues arising from PEDOT:PSS. We will investigate the effects of Au thickness and UVO treatments for optimizing device performance. Ultraviolet photoemission spectroscopy (UPS) is conducted to further analyze the WF shift at the graphene/polymer interface modified by UVO-treated Au.
