Chemical Doping and Enhanced Solar Energy Conversion of Graphene/Silicon Junctions

preprint2010arXivOpen access

Abstract

The effect of chemical doping of graphene films on the photovoltaic properties of the graphene/silicon Schottky junction solar cells was investigated. Thionyl chloride modification greatly enhanced the conductivity of graphene film, resulting in a significant improvement in cell performance with a 3-fold increase in conversion efficiency (up to 3.9%) and good short-term stability.
