Virus-Templated Interlayer Design for Organic Photovoltaic Devices |
| 초록 |
We present a novel means to control the orientation and assembly behaviors of one-dimensionally-shaped M13 viruses using a graphene surface and its use for organic photovoltaic devices. The genetically engineered M13 virus can be specifically oriented to form the densely assembled monolayer structures on graphene by aromatic pi-pi interactions. Subsequently, viral surface functionality allows for the peptide-mediated mineralization process for creating WO3 nanowire structures, which is further used for interlayer for organic photovoltaic (OPV) devices. Since the virus-templated WO3 interlayer can facilitate hole-injection properties on graphene electrode, the performance of OPV is increased substantially compared to a conventional PEDOT:PSS hole injection layer. For example, this nanostructure exhibits Voc 0.71eV and FF 50% against 0.65 eV and 38% those of graphene / PEDOT:PSS based solar cell. |
