| 제목 | Bio-Inspired Catecholamine-Derived Surface Modifier for Graphene-Based Organic Solar Cells |
| 초록 | Owing to the growing interest in next-generation solar cells, the demand for alternative transparent conducting electrodes (TCEs) has also increased. Graphene has attracted much attention as an alternative TCE because of its excellent properties. However, owing to the hydrophobicity of graphene surface, a significant amount of research has been devoted to resolve the nonwetting issue of charge-transporting materials on graphene. In this study, a thin layer of norepinephrine, an amphiphilic catecholamine derivative, was applied to graphene as a hydrophilic surface modifier. Thus, the power conversion efficiency (PCE) of organic solar cells (OSCs) fabricated with this poly(norepinephrine)-coated graphene electrode was 7.93%, which is approaching close to that of the ITO-based reference device with a PCE of 8.73%. This work represents the first demonstration of an adhesive biomaterial as an efficient surface modifier for chemically inert graphene. |
