Solid-state dewetting mediated imprinting process of gold nanodot array for ITO-free photovoltaic devices |
| 초록 |
We report the development of an efficient imprinting process for the formation of metal (Au) nanodot arrays using a square-patterned medium substrate. We found that Au-nanodots formed via templated dewetting process can be spontaneously transferred onto the desired substrate by controlling the interfacial surface free energy between the metal film and the substrate. Incorporation of the imprinted arrays to the transparent conducting oxide-free device resulted in enhanced performance, due to improved electrical properties of a polymeric electrode, which facilitated charge extraction. This imprinting process is applicable not only in the development of optoelectronic devices but also in semiconductor fabrication consisting of fabrication of metallic nanostructures. |
