本論文利用PS-b-PMMA於ITO玻璃上製作出PS奈米球狀的結構,將此結構做圖案轉移的動作,最後形成金(Au)的網狀結構,將此結構以浸泡、旋轉塗佈及Drop casting三種方式觀察P3HT是否能在特定的區域生長,希望最終能形成P3HT柱狀結構,製作出有整齊排列的Bulk heterojunction結構的高分子有機太陽能電池元件。

實驗中先製作出大小及間隔較平均的奈米球狀結構,再尋找適當的金(Au)厚度、掀離PS球時間等參數,形成將PS球完全掀離的Au pattern網狀結構,再進行以下成長P3HT柱和高分子有機太陽能電池元件兩部份實驗。

將ITO上製作的Au網狀pattern依序旋轉塗佈上PEDOT:PSS、主動層P3HT掺混PCBM之溶液、最後鍍上陰極鋁(Al)電極,製作出高分子有機太陽能電池元件。實驗中製作出四種不同結構的元件,比較有無PEDOT:PSS及Au pattern的差異。

This study utilizes PS-b-PMMA on ITO glasses to fabricate nanospherical structure for transfer-printing a reticular pattern of Au. And to observe the growing result of P3HT by three different methods as immersing, spin-coating, and drop casting. The objective is to determine whether an ordered bulk heterojuntion P3HT pillar can be formed as macromolecule organic solar cell.

The experiment initially fabricates nanospherical structure with evenly distributed dimension and distance, and then define the appropriate factors of thickness of Au, and the PS sphere‘s lift-off time. Following the setting such factors, form an Au pattern that completely lift-off the PS spheres. After that, to carry out experiments of growing P3HT pillars and macromolecule organic solar cell.

Spin coating PEDOT:PSS on Au pattern of ITO glasses, blend active layer P3HT with PCBM, followed by plating negative Al electro, and finally fabricating macromolecule organic solar cell. Four different structures items are fabricated in this test to make comparisons for the factor difference of PEDOT:PSS and Au pattern.
