Sensitized Solar Cells

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-TiO2electrodes 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.

Excellent Stability

It was investigated that the intrusion of water into the electrolyte was the most critical reason for the low stability of a dye-sensitized solar cell. To prevent the water intrusion, robust solar cells and submodules with a novel protection layer of metal circuit and tightly sealing package was developed. The excellent stability of the cell with ionic liquid electrolyte at high temperature conditions was also reveled. The resulting cell employing noble construction and ionic liquid electrolyte showed an extremely high stability to pass several endurance tests standardized in JIS for the stability of the photovoltaic submodule.
