Solution-Processable Reduced Graphene Oxide as a Novel Alternative to PEDOT:PSS Hole Transport Layers for Highly Efficient and Stable Polymer Solar Cells |
| 초록 |
We demonstrated that solution processable chemically reduced graphene oxide (pr-GO) prepared with a novel p-TosNHNH2 reducing agent can be used as an efficient anode interfacial layer for high-performance and high-stability organic solar cells (OSCs). The efficiency of the cells with pr-GO is highly comparable to those of the PEDOT:PSS-based devices. Furthermore, in air stability tests, the pr-GO-based OSCs showed a much longer cell life-time compared with PEDOT:PSS-based cells. These results clearly demonstrated that the pr-GO is a promising interfacial material and a practical replacement for conventional PEDOT:PSS, thus further advancing the realization of high-efficiency, high-stability, and low-cost OSCs by high-throughput roll-to-roll manufacturing. |
