제목 Crosslinked polymer electrolyte based on poly(ethylene glycol) and TMPTA for dye-sensitized solar cell with long-term stability.
초록 Poly(ethylene glycol) and trimethylolpropane triacrylate (TMPTA) was used as polymer electrolyte for dye-sensitized solar cells (DSSCs). With the light illumination, oligo-PEG and trifunctional TMPTA formed a crosslinked network structure. Crosslinking bond formation was confirmed by FTIR spectroscopy. The maximum ionic conductivity of crosslinked oligo-PEG was 8.42 mS cm-2 for PEG containing 20 wt % TMPTA at room temperature. Under AM 1.5 (100 mW cm-2) light irradiation for 1 min, 10 min and photo-conversion efficiencies (%) were increased from 2.37 %, 2.40 %. The efficiency was increased to 3.06 % after 170 hours of sunlight irradiation in open environment. The DSSCs containing oligo-PEG/TMPTA based electrolyte showed a good longterm stability comparing to electrolytes containing only oligo-PEG.
