技術說明

【中文】 有鑑於ITO透明導電基板具有因片電阻過高、可撓性差、與原料成本過高等問題，本發明係利用濺鍍製程將一濕潤層與一超薄(Ultra-thin)金屬層依序地形成於一透明基板之上，以製成具有低片電阻、高可撓性、高光穿透率、與低製程成本等優點的一種透明導電結構。經由實驗證實，本發明之透明導電結構可應用於有機發光二極體之製作；同時，實驗資料亦證實，具有此透明導電結構的有機發光二極體係於光取出效率、外部量子效率與功率效率等特性獲得顯著提升。並且，實驗亦證實，本發明之透明導電結構可應用於OLED與有機太陽能電池等光電元件之製作，並有助於OLED與有機太陽能電池之基礎特性的提升。 【英文】 Comparing to traditional ITO transparent substrate showing drawbacks of high sheet resistance, poor flexibility and high manufacturing cost, the present invention mainly discloses a transparent conductive film fabricated by sequentially forming a wetting layer and an ultra-thin metal layer onto a transparent substrate, wherein the transparent conductive film includes advantages of low sheet resistance, high transmittance, great flexibility, and low manufacturing cost. Moreover, a variety of experiment data have proved that, this novel transparent conductive film can not only be applied in the fabrication of some optical devices such as organic solar cell and OLED, but also helpful to the enhancement of the fundamental and essential characteristics of the optical devices.
