摘要

本研究主要是探討太陽能電池(dye-sensitized solar cell,DSSCs)之新型膠態高分子電解質，乃分別以Methacrylamide、 4-Vinylpridine 及2-(Dimeth ylamino) ethyl methyacrylate三種化合物與1,3-propane sultone進行開環磺化反應合成同時具有陰、陽離子交換基之兩性離子單體；再以AIBN (2 ,2-azobisisobutyronitril)為起始劑與Acrylic acid進行聚合反應，獲得具有導電性之水溶性膠態高分子。我們將水溶性膠態高分子添加KI和I2使它具有氧化還原對，作為染料敏化太陽能電池中電解質的應用。
再將新型膠態高分子電解質作性質結構的分析，利用FT-IR和NMR進行結構上的鑑定，再以四點探針(Four point probe)和循環伏安法(Cyclic Voltammetry)進行導電度的測量與電化學的分析。結果得之，新型膠態高分子電解質導電度高達10-3，不但與液態電解質具有相似的高離子導電度，更可以改善液態電解質容易洩漏的缺失，而提高在染料敏化太陽能電池應用上的長期穩定性。

The research was focus on novel gel polymer electrolyte for dye-sensitized solar cell. The initiator (1, 3-propane sultone) proceeds to the open-ring sulfonation reaction with methacrylamide, 4-vinylpridine and 2-(Dimethylamino)ethyl methyacrylate to become the zwitterionic monomers that contains positive and negative charges. The gel polymer electrolyte for dye-sensitized solar cell was synthesized by adding AIBN (2,2-azobisisobutyronitril) and acrylic acid which dissolved in water and had high ionic conductivity, adding the iodide/triiodide(I -/ I3 -) to the polymer.
To ensure its structure, we use FT-IR,NMR to determinate and analyze it with Four Point Probe and Cyclic Voltammetry in conductivity and electrochemistry property analysis.
As a result, the novel gel polymer electrolyte was 10-3s/cm, the same as liquid electrolyte. It can improve the liquid electrolyte leak out easily, and enhance the stability of dye-sensitized solar cell devices.
