摘要(中)

本文研究以網印技術印製銀導線電極圖案，結合剝離技術(Lift-off)將所印製之電極圖案崁入至聚醯亞胺(Polyimide)基板內。由於網版印刷技術擁有快速、大面積、無需真空與製程簡單等優勢，可取代現階段耗時、耗能的真空鍍膜製程。本文第一部分針對金屬網格透明基板之基本特性作探討，包括金屬網格設計、透光度與彎曲疲勞等特性。本文的第二部分於金屬網格透明基板上塗佈導電高分子 PEDOT:PSS作為修飾平坦層，以降低電極之表面粗糙度，同時，為了進一步增進透明電極之光電特性，在製備PEDOT:PSS溶液時中添加不同比例MoOx水溶液與銀奈米粒子，這些添加對元件特性的影響，則透過電洞注入元件(Hole-only device, HOD)作測試。本文的第三部分是將所開發的金屬網格透明電極應用於有機發光二極體 (Organic light emitting diode, OLED)元件之製程，證明其可行性。

摘要(英)

This thesis aims at developing a fabricating technique for metal-mesh transparent electrodes. The approach includes the uses of the screen printing method for patterning metal mesh on a glass substrate and the lift-off method for embedding the printed mesh into a flexible polyimide substrate. As the screen printing is a fast and straightforward mass production method, it has the potential for replacing the current time and energy consuming vacuum coating process. The first part of this thesis discusses the basic characteristics of the fabricated metal mesh transparent substrate, including the metal mesh design, light transmission, bending life and other related characteristics. The second part is to coat the embedded mesh electrode with a layer of conductive polymer, PEDOT:PSS, as a modifying flat layer for reducing the surface roughness of the electrode. In order to further improve the photoelectric properties of the metal-mesh electrode, different proportions of MoOx and silver nanoparticles are blended with the PEDOT:PSS by mixing PEDOT:PSS solution with aqueous MoOx and silver nanoparticles solutions. The resulting effects are examined by characterizing a Hole-only device (HOD). By employing the developed metal mesh electrode as the anode of an organic light emitting diode (OLED), the third part of this thesis discusses its feasibility.
