홈페이지논문 초록 (Abstract)
Metal network based transparent conducting electrodes are essential for the future optoelectronic devices due to their mechanical flexibility and compatible with large-scale manufacturing. In this report, we investigated the morphological, optical, electrical, and flexible properties of an electrodeposited silver (Ag) mesh transparent conducting electrodes based on a self-cracking template. An overly coated Ag mesh (ED-TE Ag mesh) was prepared onto glass and PET substrates by the sequential deposition steps including thermal evaporation and electroplating methods. The self-cracking template was lift-off prior to the over coating of Ag by the electrodeposition step. The surface morphologies of ED-TE Ag meshes are smooth and well interconnected. The Ag mesh thickness and line width are typically increased with the electroplating time from 0 s to 30 s. The ED-TE Ag mesh shows higher optoelectronic performance with a larger figure of merit (2827 (Ω/sq)−1) than the individual evaporated Ag mesh (756 (Ω/sq)−1) and the ITO film (311 (Ω/sq)−1). Moreover, the low sheet resistance (1.01 Ω/sq) of the ED-TE Ag mesh is observed at 30 s. The ED-TE Ag mesh exhibits almost stable resistance to both concave and convex bending tests, even at a smaller radius of curvature (<2 mm). Thus, these electrodes are more suitable for many flexible device applications like solar cells, displays, etc.
