23_42/2011Organic Solar Cells: Solution-Processable Reduced Graphene Oxide as a Novel Alternative to PEDOT:PSS Hole Transport Layers for Highly Efficient and Stable Polymer Solar Cells (Adv. Mater. 42/2011)

Solution-processable reduced graphene oxide as a hole-transporting layer for highly efficient and stable organic solar cells is reported on page 4923 by Dong-Yu Kim, Seok-In Na, and co-workers. Introduction of a newly reduced graphene oxide by simple solution processing into solar cells dramatically raises the cell efficiency and cell life-time. The results will allow full use of chemically reduced graphene and will advance the realization of carbon-based printable optoelectronic devices.
