A noticeable Li-TFSI film as a quasi-solid-state electrolyte for fiber-shaped dye-sensitized solar cells with outstanding stability |
| 초록 |
The fiber-shaped DSSCs represent promising solar-to-electricity conversion devices for next generation due to simple fabrication method and good wearability. However, the traditional process of DSSCs includes liquid electrolytes, which lead to low stability due to the leakage of liquid electrolytes. To solve these problems, some quasi-solid and solid-state electrolytes have been applied in DSSCs. We explore for the first time the usage of Li-TFSI film as a quasi-solid-state electrolyte (QSE), which was introduced for improving the efficiency and the stability. The compact TiO2 was prepared on a Ti wire through electric heating, which was followed by a coating process with TiO2 colloids to form mesoporous layer. The dye underwent the dipping process. The Li-TFSI was wrapped and then the electrolyte was adsorbed. The DSSC, in which Li-TFSI film was used as a QSE, showed good efficiency and maintained more than 90% of its efficiency even after several weeks. |
