Silver nanowire electrodes attract significant attention in flexible and transparent optoelectronic devices. Here, we have introduced a simple technique for high-resolution patterning of AgNW networks, based on simple filtration of AgNW solution on a patterned polyimide shadow mask. This technique enables the high-resolution patterning of AgNW electrode down to a width of 3.5 μm. Moreover, the patternd AgNW electrode could be transferred various arbitrary substrate, such as silicon, glass and PET. Finally, we fabricated flexible and semi-transparent UV photodetectors based on ZnO with AgNW electrode. AgNW electrodes are embedded in ZnO films to enhance the photocurrent by light scattering and trapping. In addition, our photodetector could be operated well under extremely bent conditions and provide excellent durability. The proposed patterning technique of AgNWs has a significant potential for applications in the development of flexible and transparent optoelectronic devices. |
