The most Ru dyes for dye-sensitizer solar cell are mononuclear dyes.Absorption band of mononuclear dye appearing at 350nm to 600nm.We use bridge ligand with conjugated structure to connect the two Ru metal centers. High conjugated structure of the dinuclear dye improve molar extinction coefficient and move absorption band to red region of the visible spectrum and increase molar extinction coefficient to increase light to electric conversion efficiency.A dinuclear dye with two Ru metal centers excited two electrons to inject into TiO2 under solar power,compared with mononuclear dye. The main drawback of mononuclear dye is lack of absorption in red region of the visible spectrum and relatively low molar extinction coefficient. Dinuclear dye would to improve efficiency.
