Surfactant effect on the photovoltaic performance of polypyrrole and polypyrrole with multi wall carbon nanotube as pt-free counter electrodes for DSSC application. |
| 초록 |
A dye sensitized solar cell (DSSC) employing a polypyrrole-1 (PPy1), polypyrrole-2 (PPy2) and polypyrrole-2/multi wall carbon nanotube composite film (PPy2/MWCNT) counter electrodes (CEs) modified by different electrolyte composition. It is shown that the introduction of anionic surfactant, sodium dodecyl sulfate (SDS), 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%). |
