Processable, single-layered graphene oxide (GO) is an intriguing nanomaterial with tremendous potential for electronic applications. We spin-coated GO thin-films on quartz and characterized their sheet resistance optical transparency using different reduction treatments.

Abstract A soluble graphene, which has a one‐atom thickness and two‐dimensional structure, is blended with poly(3‐hexylthiophene) (P3HT) used as the active layer in bulk heterojunction (BHJ) polymer photovoltaic cells. Adding graphene to P3HT induces great quenching of photoluminescence P3HT, indicating strong electron/energy transfer from graphene. In devices an ITO/PEDOT:PSS/P3HT:graphene/LiF/Al device efficiency increases first then decreases increase content. The containing only 10 wt %...
