Back Cover: Ternary Organic Solar Cells with Reduced Graphene Oxide–Sb₂S₃ Hybrid Nanosheets as the Cascade Material (ChemNanoMat 5/2015)

The Back Cover illustrates the use of reduced graphene oxide-antimony sulfide (rGO-Sb2S3) hybrid nanosheets as the cascade material in ternary organic solar cells. Their utilization in PCDTBT:PC71BM blend leads to power conversion efficiency of 6.81%; a value 23% higher than the efficiency of the binary devices. The results demonstrate that the exploitation of on-demand functionalized graphene derivatives as electron cascade materials is a promising way towards improving the performance of organic photovoltaics.
