Application of ultrathin polypyrrole nanosheets (UPNSs) as a counter electrode for dye-sensitized solar cell |
| 초록 |
Ultrathin polypyrrole nanosheets (UPNSs) were fabricated by soft template polymerization method using Sodium Decylsulfonate(SDSn) hydrate crystal in aqueous medium. Average width and thickness of synthesized UPNSs is about 10μm and 50nm. The UPNSs were coated onto fluorine-doped tin oxide (FTO) substrate to use as CE in DSSCs. The performance of the PPy-based DSSCs was characterized by cyclic voltammetry, current density-voltage measurements and electrochemical impedance spectroscopy. The DSSC using UPNSs counter electrode showed overall power conversion efficiency (5.4%) compared with that of the conventional Pt-based DSSC (5.9%), under 100 mW•cm–2, AM 1.5 G sunlight illumination. |
