Abstract

The traditional organic ruthenium dyes have some disadvantages, such as the routes of the synthesis of ligands being too time-consuming, the separation and purification of the ligands being difficult, the lower photo-electric conversion efficiency and so on. In view of these disadvantages, we designed and synthesized a new 9,9-[di-(2-ethylhexane]-4,5-diazafluorene ligand. Then we got the dye-sensitized solar cell using this ligand. Such ruthenium dye contains a kind of derivative of 4,5-diazafluorene ligand, and comparing with the traditional bipyridine ligands, the synthetic route is more simple and it’s suitable for large-scale practical application. The short-circuit current (Jsc), open-circuit voltage(Voc), fill factor (ff) and photoelectric conversion efficiency(?) of the prepared dye-sensitized solar cell is 14.75-15.02 mA/cm2, 681-696 mV, 0.66-0.70, 6.8-7.0 % respectively, when measured in the standard AM 1.5 simulated sunlight.
