Novel triblock copolymer/TiO2 composite gel electrolytes for high-performance dye-sensitized solar cells |
| 초록 |
Two types of triblock copolymers were prepared using the RAFT-polymerization, which have the structure of PEG-b-(P(AN-co-BMAAm))2 (SGT-602) and PEG-b-(P(AN-co-DMAAm))2 (SGT-604). The gel electrolyte including SGT-604 or SGT-602 was electrochemically investigated by the symmetrical cell test and introduced to dye-sensitized solar cells (DSSCs). TiO2 nanoparticle was employed to the gel electrolytes in order to improve the cell performance. The optimized composition of TiO2 nano-filler was 10 wt% to total weight of the polymer gel electrolyte. The resulting TiO2 composite gel electrolytes showed efficiencies of 9.30% and 9.39% for TiO2 composite gel with SGT-602 and SGT-604, which is comparable to that of the liquid electrolyte (η: 9.86 %). Electrochemical impedance spectra (EIS) were analyzed to explain the photovoltaic parameters. Finally, Evolution of normalized efficiencies was traced under 1 sun illumination at 50 ˚C. |
