| Popis: | We studied the competition between energy loss due to quenching and enhanced absorption arising from the near-field plasmonic effect of Au nanoparticles (NPs) on the performance of organic solar cells (OSCs), by fabricating inverted architecture OSCs with electron transport layers consisting of an Au NPs monolayer covered by a ZnO overlayer. The distance between Au NPs and a poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) active layer was controlled by systematically varying the ZnO overlayer thickness, and its effect on the absorption spectra, photoluminescence (PL) dynamics, and OSC performance of these films is examined. We found that when P3HT:PCBM is in direct contact with the Au NPs, PL intensity was reduced and the OSC device was shunted with lower values in photocurrent, open circuit voltage, and fill factor. With a thin (8 nm) ZnO overlayer, higher absorption and PL signal were observed, and some OSC device parameters improved, but the short circuit current density r... |
