| dc.description.abstract | This study aims on developing a scalable, screen-printing based process for fabricating low surface roughness, embedded metal-mesh transparent electrode on a flexible substrate. This method takes the advantages that all fabricating processes are exectable at room temperature and in the ambient environment. To further reduce the the electrode’s surface roughness and increase the effect of current diffusion during the device’s lighting process, a surface modification layer of conducting polymer, PEDOT:PSS, is used. This layer also helps to impede current leakage and avoid short circuit at the lighting duration. Measurements show that the obtained embedded silver-mesh electrode has excellent properties in transmittance, sheet resistance, surface roughness, and mechanical bending characteristics, superior to that of ITO electrode. As serving as the anode in a white OLED device, the present metal-mesh based device also demonstrates better electrical and
luminescent characteristics than that based on the ITO electrode. | en_US |
