摘 要
本研究以光電轉換過程來進行太陽能轉換,製備高分子錯合物多層薄膜作
為光反應電極,利用同步循環伏安儀 (SCV) 及光照實驗觀測,探討光機能
性分子、電子受體、電子授體物種，在光能轉換過程中光電子移動特性。
並由光反應電極調製條件的改變，獲得了光誘發電流的提升。
研究顯示光機能性分子Ru(bpy)32+在光電轉換過程中，進行氧化猝滅反應
，所釋出的電子將受體分子還原，授體則提供電子給予氧化態的Ru(
bpy)33+。
實驗採用全固態三明治式之雙電極 (twin electrode)，組合適當的光機
能性分子、電子受體，將此雙電極組進行光誘發電流實驗，並以同步分光
循環伏安譜及單層薄膜研究結果，探討ITO/Nafion-Ru(bpy)32+//PB/ITO
組合中電子移動特性。當加入電子授體PANI，多層薄膜系統的光誘發電流
可達到數十個mA。最後建立多層薄膜組合ITO/PANI/Nafion-Ru(bpy)32+/
PB/ITO光激發電子傳遞之機構。
實驗另針對Nafion薄膜、Clay薄膜對電化學活性物種不同之影響，構築新
的雙電極組ITO/Nafion-Ru(bpy)32+//PB-Clay/ITO去探討光電特性，結果
光誘發電流可達到十幾個mA。
The solar conversion was by photo-electro process in my study.
Photoresponse electrode was prepared by using modified membrane
of polymer-complex. Study used in-situ spectrocuclic voltameter
and irradiation experiment to observe the photoelectron transfer
in photo-electeo conversion process. System included
photoreaction center,melectron acceptor and electron donor. By
improved the prepared way of photoresponse electrode,
photocurrent was promoted.
Photoreaction center proceed oxidation quenching in photo-
electrode conversion, and it release the electron to reduce
electron acceptor. In the same electron donor give electron to
photoreaction center.
In experiment used sandwich type twin electrode, to combine
photoreaction center, electron acceptor.The twin electrode got
photo-induced current in irradiation experiment, and SCV gived
the information for photoelectron transfer in the twin
electrode. When electron donor was added in the twin electrode,
photo-induced current approached ~25 mA. Finally, we established
the mechanism of photoelectron transfer for the mutlilayer of
the twin electrode (photoreaction center, electron donor and
electron acceptor).
Because electroactive species appeared different behavier in
Nafion membrane and clay membrane, we setted up a new twin
electrode,ITO/Nafion-Ru(bpy)32+//PB-Clay/ITO. Photo-induced
current of the twin electrode included photoreaction center and
electron acceptor could approach ~15 mA.
The solar conversion was by photo-electro process in my study.
