Interfacial Modification with Bis-Fullerene Self-Assembled Monolayers for High-Efficiency Inverted Polymer Solar Cells |
| 초록 |
We demonstrate highly efficient inverted polymer solar cells (iPSCs) employing mono- and bis-fullerene self-assembled monolayers (mono-FSAMs and bis-FSAMs) as an interfacial layer between organic active layer and inorganic TiOX layer. The iPSCs have been fabricated with a configuration of ITO/TiOX/(FSAMs)/PTBT:PCBM /MoO3/Au, where PTBT and PCBM are used as an electron donor and an acceptor, respectively. The device with pristine TiOX layer exhibits the power conversion efficiency (PCE) of 3.28%, whereas the device with mono- and bis-FSAMs shows remarkably improved PCE of 4.32% and 5.13%, respectively. These high PCEs result from the enhancement in both of short-circuit current (JSC) and fill factor (FF), which are attributed to improved exciton dissociation efficiency by providing additional PTBT/FSAMs interface, and reduced contact resistance and incompatibility at active layer/TiOX interface, respectively. |
