The Enhanced performance of the dye-sensitized solar cells based iongel containing the cellulose |
| 초록 |
Dye-sensitized solar cells (DSSCs) have been focused considerable attention due to their power conversion efficiency, a reasonable cost, and simple preparation processes. The general electrolytes for DSSCs are composed of redox mediator dissolved in liquid organic solvent. But the liquid electrolytes in DSSCs are caused by leakage and evaporation of electrolytes for practical usage. To overcome these problems, iongel electrolytes which were made of ionic liquid with a small amount of cellulose were applied for DSSCs. The phase change from liquid state to quasi-solid state when the cellulose were added to liquid electrolytes. The pre-iongel electrolytes were applied into the DSSCs to improve penetration of the electrolytes before the gelation time. Then the DSSCs were stored at room temperature at least for 24 hours for formation of iongel. The diverse measurement were conducted in order to evaluate the performance of DSSCs. |
