設計了三個新型的染料:PC系列染料PC101 、PC102、 PC103，想利用多個Anchoring Group來增加染料注入電子到半導體層的能力，並且利用Dπ2A形式的染料來延伸共扼系統，希望能得到較紅位移的吸收光譜，並且設計Pyridine與Carbazole等三個含氮雜環所組成的三螯合配位基Dipyridyl-carbazoles (1,8-Di( pyrid-2’-yl ) Carbazoles ) Ligand 螯合金屬離子，本篇最主要的目的是為了探討金屬對有機染料共扼系統結構的影響，看看是否能影響組裝成電池元件後的效率，希望金屬的影響能對效率有正面的改善。 ;Dye-Sensitized Solar Cells (DSSCs) is characterized by thin, flexible, being made of large area, and so on. So it does agree with the area of solar generator developments. The purpose is to enhance the efficiency of conversion of solar-to-electrical energy, and there have many factors to effect the conversion of solar-to-electrical energy. This thesis synthesize novel metal complexes to improve the solar-to-electrical conversion efficiencies. We design the new type metal complexes ( PC101-PC103 ) for dye-sensitized solar cell applications,There dyes exhibit beter electron injection and longer wavelength absorption than their congener with only one anchor. We also design the new type ligands Dipyridyl-carbazoles ( 1,8-Di ( pyrid-2’-yl ) Carbazoles )to chelate metal ion .We will probe the metal complexes influence for organic-dyes. We hope the metal complexes containing 1,8-di( pyrid-2’-yl ) carbazole (Dipyridyl-carbazoles) ligands for dye-sensitized solar cell to have the high-performance.
