High-performance flexible transparent nanomesh electrodes

摘要： A cost-effective process for producing high-performance Ag-paste-based flexible transparent nanomesh electrodes was developed by optimizing their linewidth, pitch, and height. These nanomesh electrodes, with a linewidth of several hundred nanometers and a pitch of 10–200 μm on a PET substrate, achieved wide ranges of transmittance (83.1–98.8%) and sheet resistance (1.2–30.9 Ω/sq) and a figure of merit (992–1619) superior to those of indium tin oxide (ITO) and silver nanowire (AgNW) electrodes. Our evaluation of their flexibility (testing up to 50,000 cycles) and their electromagnetic interference shielding effectiveness verifies the applicability of these flexible transparent nanomesh electrodes to various flexible optoelectronic devices.
