High-Performance Flexible Transparent Electrode Fabricated by Solution Process |
| 초록 |
Transparent conducting electrodes (TCEs) are critical component of optoelectronic devices including flat panel displays, touch screen displays, solar cell, and organic light-emitting diodes (OLED). Although indium tin oxide (ITO) is commonly used for this purpose, the expensive deposition process of ITO and the incompatibility with flexible electronics, due to the brittleness of thick films, limit their use in roll-to-roll processes. Recently, great efforts have been attempted to develop a new transparent electrode which can be mass-produced at a low cost, large area and excellent flexibility for a flexible electronic device. Here, we present simple, low-cost and scalable routes to developing flexible Cu TCEs with a low sheet resistance Rs ＜ 1 Ω/sq and a high transmittance T ＞ 90 % at 550nm. Metal mesh patterns were fabricated by combination of infiltration of metal flakes and electroless plating on poly(dimethylsiloxane) (PDMS) mold with 5 μm wide and 8 μm deep trench. A sheet resistance and transmittance of TCEs were precisely controlled by varying line width and line spacing of Cu mesh patterns. This fabrication technique enables the mass production of large-area flexible TCEs, and the stability and high performance of mesh electrodes in high bending stress suggests they have high possibility for application in smart displays and flexible transparent heater. |
