Counter Electrode Optimization with Multi-wall carbon nanotube for the Pt-free DSSCs |
| 초록 |
A dye sensitized solar cell employing a polypyrrole-1, polypyrrole-2 and polypyrrole-2/multi wall carbon nanotube composite film counter electrodes modified by different electrolyte composition. It is shown that the introduction of anionic surfactant, sodium dodecyl sulfate , enhanced the catalytic activity, thus leading to an improvement in the performance of PPy2. Further, introduction of MWCNT resulted in increase in conversion efficiency of DSSCs with PPy2/MWCNT composite film. The Tafel and electrochemical impedance analysis revealed that the PPy2 and PPy2/MWCNT CEs prepared with anionic surfactant possessed more catalytic activity and lower charge transfer resistance in comparison with PPy1-based CE. This resulted in a better conversion efficiency of 5.88% for PPy2/MWCNT- based DSSC under 1 sun condition, reaching 86% of the DSSC based on reference CE (6.86%). |
