Towards fabrication of high-performing organic photovoltaics: Atomic layer deposited thin buffer layer and plasmonic Effects |
| 초록 |
The inverted OPV were fabricated by wet-chemically prepared ZnO and PEDOT:PSS as buffer layers. Particularly, for PEDOT:PSS deposition, no annealing step was employed. This inverted OPV showed a PCE of 7.0 %, which is comparable to the hitherto reported highest efficiency of the inverted OPV with vacuum-deposited MoO3 as hole-collecting buffer layers without plasmonic enhancements. Incorporation of Au naoparticles in PEDOT:PSS was used for plasmonic enhancement of the electromagnetic field, whereas ZnO thin layers were deposited on ZnO using atomic layer deposition for quenching electron-hole recombination at surface defects of ZnO ripples. These additional treatments could be used for improving the performance of OPV, which ultimately resulted in a PCE of 7.9 %. |
