Cu Mesh for Flexible Transparent Conductive Electrodes

摘要: Copper electrodes with a micromesh/nanomesh structure were fabricated on polyimide substrate using UV lithography and wet etching to produce flexible transparent conducting (TCEs). Well-defined mesh realized through the use of high-quality Cu thin films. The films radio-frequency (RF) sputtering single-crystal target—a simple but innovative approach that overcame low oxidation resistance ordinary Cu. Hybrid by adding capping layer either ZnO or Al-doped ZnO. sheet transmittance electrode an 6.197 ohm/sq 90.657%, respectively figure merit was 60.502 × 10–3/ohm, which remained relatively unchanged after thermal annealing at 200 °C 1,000 cycles bending. This fabrication technique enables mass production large-area TCEs stability high performance hybrid in harsh environments suggests they have strong potential for application smart displays solar cells.
