A double-bond-edged Ru dye (code name: SG1051) has been studied as a novel sensitizing dye for ultradurable dye-sensitized solar cells (DSCs). The SG1051 Ru dye showed the quick dye-uptake time (1 h for the optimized condition: η=9.2%, using volatile electrolyte) and the strong adsorption strength compared with standard Ru dyes (N719 and Z907), which was checked by successive dipping of dye-adsorbed nanocrystalline-TiO2 electrodes into NaOH aqueous. solution and acetonitrile. The resulting DSCs using SG1051 Ru dye and ionic-liquid electrolyte survived the durability test at 120°C for 480 h, which can be the strong interest of the industrial groups
