Slot-Die Coated Organic Solar Cells with Improved Device Performance and Stability by Introduction of Water Processing |
| 초록 |
In recent years, device performance of organic solar cells (OSCs) has dramatically increased and reached up to 18% for the single-junction structure. However, many issues of efficiency and stability of bulk heterojunction OSCs are still at issue. In particular, the optimization of the film morphology of active layer is very important for high performance and long-term stability because the power conversion efficiency (PCE) is mainly determined by the three-dimensional structure in the donor-acceptor blended system. In this study, we fabricated the slot-die coated OSCs by introducing water processing as an additional treatment. Furthermore, we confirmed that the bulk heterojunction morphology and device performance depend on the quantity of water introduced in active solution. As a result, 12% (PTB7-Th:PCBM), 11% (PTB7-Th:EH-IDTBR) and 12% (PM6:Y6)-improved PCEs compared with as-cast reference cells were achieved from the water processing. |
