Association of acidity in Polyfluorene based-Electrolytes with the Photovoltaic Properties |
| 초록 |
The interfacial effect on photogenerated holes and electrons transfer is known related with a Schottky barrier and the resistance of device. Herein, we investigated the association of acidity in polyfluorene based-electrolytes (PFN) with the photovoltaic properties, such as the Schottky barrier and the resistance of device. The PFN has been famous, but the association between PFN and acid is rarely investigated. Thus, we selected four materials with different acidity, where the pKa value are from 4.7 to -2.8. The power conversion efficiencies (PCEs) were performed to investigate the effect of acidity. To explain the photovoltaic parameter, especially the short-circuit current density (Jsc) and the fill factor (FF), the Kelvin probe microscopy and the impedence spectroscopy were performed. The result shows well-matched association with the photovoltaic properties, where the high Jsc correspond to the low Schottky barrier and the high FF correspond to the high recombination resistance. |
