Flexible transparent electrodes are critical components of flexible electronic devices such as smart window, touch screens, organic solar cells, and organic light-emitting diodes (OLEDs). Considerable efforts have been made to develop flexible transparent electrodes, for example, carbon nanotubes (CNTs), grapheme, silver nanowires (AgNWs) and grids. 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 low. This value is too high for use with organic solar cells, which require low sheet resistances (~10 Ω/□) and high transparency (~80%). Thus, a substantial improvement in the sheet resistance of CNT films is a necessity. Among these materials, AgNWs exhibit excellent electrical conductivity because silver has the lowest resistivity, cost-effective and solution processability. In this work, the fabrication by spray coated process of transparent CNT/AgNW multilayer electrodes on PET substrates is researched. The changes in electrical and optical conductivity of CNT/AgNW multilayer electrodes were discussed. CNT/AgNWs multilayer electrodes using the performance of organic solar cells were investigated. |
