Fluorine-substituted Conjugated Oligo-electrolytes as the Electron Transfer Layer in Inverted Organic Solar Cells |
| 초록 |
Two easily accessible fluorene-substituted conjugated oligo-electrolytes (COEs), FTF- and FBF-NBr, have been developed as the electron transfer layers (ETLs) in inverted type organic solar cells (iOSCs). The iOSCs with ETLs show to improve the power conversion efficiency (PCE) and time-dependent stability of the cell that utilizes a high work function cathode. FBF- and FTF-NBr significantly improve the device parameters compared to the reference solar cells without ETLs, as reduce the work function of indium thin oxide (ITO). In this work, COEs have low HOMO levels -5.54 eV and -5.77 eV for FTF-NBr and FBF-NBr in order, which are favorable to hole-blocking ability. In order to investigate the effect of ETL on the photovoltaic properties, the iOSCs with FBF- and FTF-NBr as the interlayer at the cathode side were fabricated. As a result, the PCE of 7.89% with FBF-NBr and 8.05% with FTF-NBr as the ETL has been achieved. |
