Carbon counter electrode and gel electrolyte of dye-sensitized solar cells for improved stability |
| 초록 |
Platinum (Pt) in counter electrode (CE) of dye-sensitized solar cells (DSSCs) is a high-priced metal and tends to be corroded by electrolytes through long-term exposure. Leakage and volatilization of the liquid electrolyte also limit the long-term stability of DSSCs. In our group, various carbonaceous nanomaterials were investigated as alternatives to replace Pt CE. Hybridization of the carbonaceous materials with minor amounts of catalytic Pt significantly improved the electro-catalytic performances of the carbon CEs. An initiator- and monomer-free UV-cross-linkable block copolymer was designed and synthesized for controlled in-situ gelation of electrolytes in DSSC. A composite separator membrane with a layered structure was also inserted in electrolyte, demonstrating desirable combination of short- and long-term performances of DSSC. The combination of the carefully designed CE and gel electrolyte are believed to be beneficial for the success of DSSC, especially for flexible devices. |
