摘要

由於4-tert-butylpyridine(4TBP)成功提升染料敏化太陽能電池的光電轉換效率，證明含氮雜環與電池元件間交互作用影響了電池表現。本研究選擇兩種苯並咪唑衍生物，以不同的濃度做添加，並與4TBP做雞尾酒式的混合，測試其光電轉換效率之良莠。並利用計時電流法與紫外光/可見光光譜測量含有添加物之電解質溶液的特性差異；再以I-V curve、IPCE與EIS測量對電池元件的光電轉換效率、入射光子-電子轉換效率，以及電池內部電阻間的變化，佐證添加物對電池效率的影響。

Because of 4-tert-butylpyridine(4TBP) enhanced the photo-electron conversion efficiency successfully as an additive in electrolyte solution. Therefore, the interaction between nitrogen heterocycle as an additive and solar cell components cause influence on cell performance. In this thesis, we choose two bis-benzimidazole derivatives in different concentration and also mix with 4TBP to find out if they enhance or reduce efficiency of dye-sensitized solar cells. Using chronoamperometry and UV/Vis to find out the differences between electrolytes. Using I-V curve, IPCE and EIS to define photo-electron conversion efficiency, incident photon-to-electron conversion efficiency and impendence inside cells to prove additives do make influence on dye-sensitized solar cells.
