在眾多再生能源中，染料敏化太陽能電池將太陽光能轉換為電能，是未來可供給大量能源較為可靠的一種再生能源。染料敏化太陽能電池中，光敏染料是其中一個重要元件，其吸收太陽光輻射，並將其轉換為電能。過去，一些含有硫氰配位基的釕錯合物染料在所有已開發的染料居於領先地位。本篇論文中，我們設計了不含硫氰配位基的新型釕錯合物染料，並且報導了一個較好的合成法。我們希望這樣的新型染料結構可以得到好的光電轉換效率。 The conversion of sunlight to electricity using dye-sensitized solar cells (DSSCs) represents one of the most promising methods for future large-scale power production from renewable energy sources. In these cells the sensitizer is one of the key components, harvesting the solar radiation and converting it to electric current. In the past, ruthenium dyes endowed with thiocyanate ligands have maintained a clear lead in performance among thousands of dyes that have been published. Here, we design a novel thiocyanate-free cyclometalated ruthenium complex and report a better method for cyclometalated ruthenium complexes synthesis. We hope the utilizing of cyclometalated ligands could replace thiocyanate ligands to get good performance in DSSCs.
