High-Efficiency and Stable Mesoscopic Dye-Sensitized Solar Cells Based on a High Molar Extinction Coefficient Ruthenium Sensitizer and Nonvolatile Electrolyte

摘要

Mesoscopic dye-sensitized solar cells (DSCs) with more than a 10.5 % photoelectrical conversion efficiency were obtained utilizing the newly designed high molar extinction coefficient sensitizer (K77) in conjunction with a volatile electrolyte (Z675). Highly efficient DSCs (up to 9.5 %) exhibiting unprecedented long-term stability (1000 h) under both light soaking and thermal stressing have been obtained using the K77 sensitizer in combination with a newly formulated nonvolatile organic-solvent-based electrolyte (Z646).
