本研究主要是探討聚三辛基塞吩和奈米碳管的複合材料製作及光電性質量測。為了使元件工程進行得更順利，必須從碳管及高分子的單一材料控制和鑑定開始。
直接成長碳管方面以密度控制和長度控制為主題，以成長直立陣列碳管為目標。高分子的基礎鑑定則以旋鍍轉速和成膜品質的關係為第一部份；第二部分則是探討高分子因退火效應結晶化的光學及電學研究。
第三部分則是製作複合材料及電性量測。實驗結果方面，直接成長碳管於基板上的策略遭遇重大的挫折，並瞭解到將聚三辛基塞吩填充入奈米結構中是一難度極高的工程問題。解決界面工程的策略是採用表面改質技術。除了電性量測外、並使用時間解析光譜測定，發現到載子存在時間隨著碳管密度的增加有減少的趨勢。

In this thesis, the engineering part of the solar cell of spin coating, annealing and composite fabrication were studied. In theory, the direct growth aligned carbon nanotubes and P3OT can be fabricated into the composite and have high solar energy conversion efficiency, the direct growth carbon nanotubes can serve as conducting channel to extract electron out of the composite. However, this kind of structure’s fabrication shows high difficulty in engineering aspect. The poor coverage of the P3OT on carbon nanotubes indicates that there exists interface problem between the carbon nanotubes and P3OT.
First, we have to make sure what the important parameter determines the polymer solar cell’s efficiency. After investigating the spin coating rate influence, we found that the spin rate only affect the P3OT’s thickness.
Second, we study the annealing effect on the P3OT’s structure. The amorphous conducting polymer needs to become crystallized that polymer’s application on electronics can become possible. We characterize the structure by absorption spectrum, photoluminescence spectrum, X-ray diffraction. And found the ordering’s evidence in the spectrum: Absorption spectrum’s peak splitting, PL spectrum’s Huang-Rhys Factor decreases as annealing temperature increases, this phenomenon shows that effective conjugation length of the polymer chain increases. X-ray’s results shows that the d-spacing of the polymer decreases, shows that the packing of the structure become denser.
Finally, we study the P3OT / Direct Growth Aligned Carbon Nanotubes composite fabrication. Applying length controlled and density controlled carbon nanotubes on this structure and using surface modification technique to increase the hydrophilicity of the carbon nanotbes surface in order to overcome the interface coverage problem. The electric properties of the composite has been characterized.
