Photo-crosslinkable polymeric electrolyte system based on poly(ethylene glycol) and poly(ethylene glycol) diacrylate for dye-sensitized solar cells with long-term stability. |
| 초록 |
Poly(ethylene glycol) (PEG) and poly(ethylene glycol) diacrylate (PEGDA) were used as photo-crosslinkable polymeric electrolytes for dye-sensitized solar cells (DSSCs). PEG and di-functional PEGDA formed a crosslinked structure upon light illumination, as confirmed by the solubility test and FTIR spectroscopy. In order to make close contact with the TiO2 porous film, the polymeric electrolytes were prepared by photo-polymerization after injecting the monomer electrolyte solution into the porous TiO2 layer. Under AM 1.5 (100 mW/cm2) light irradiation up to 20 min, maximum 62 % increase in photo-conversion efficiency (%) was observed. The electrolyte containing PEG and 15 wt% PEGDA showed a maximum increase in the photo-conversion efficiency from 2.58 % to 4.18 % with 20 min of light illumination. Also, DSSCs with photo-crosslinkable PEG/PEGDA based electrolyte showed improved long-term stability in comparison to those electrolytes containing only PEG. |
