Fabrication of Flexible Transparent Conducting Film using CNT/AgNWs Multilayer Electrodes |
| 초록 |
Flexible transparent electrodes are critical components of flexible electronic devices such as smart window, touch screens, solar cells, and organic light-emitting diodes (OLEDs). Considerable efforts have been made to develop flexible transparent electrodes, for example, carbon nanotubes (CNTs) and graphenes and random networks of silver nanowires (AgNWs). Compared with expensive indium tin oxide (ITO) films, CNT transparent electrodes may have significantly lower costs owing to the abundant availability of source materials and coating processes. However, the sheet resistances of CNT transparent electrodes are 100 Ω/□ with a transparency of 80%. This value is too high for use with organic solar cells and OLEDs, which require sheet resistances of approximately 10 to 50 Ω/□. Thus, a substantial improvement in the sheet resistance of CNT films is a necessity. Among these materials, AgNW transparent electrodes exhibit excellent electrical conductivity because silver has the lowest resistivity (as low as 1.59 × 10-6 Ω∙cm), cost-effective and scalable roll-to-roll manufacturing. In this work, the fabrication by bar-coated process of transparent CNT/AgNWs films on PET substrates is researched. The changes in electrical and optical conductivity of CNT/AgNWs multilayer electrodes were discussed. |
