Highly Efficient and All-Solution-Processed, Intrinsically Stretchable Organic Solar Cells |
| 초록 |
Recently, development of stretchable organic solar cells (SOSCs) have attracted considerable attention as an off-grid power source for wearable electronics such as biosensors, electronic skins, and stretchable displays, owing to their unique features of high power-per-weight output and robustness on repetitive tensile strains. In this work, we focused on realizing highly efficient SOSCs with over 11% PCEs that maintained a performance of 74% of initial PCE when subjected to 10% strain 1,000 times. Specifically, TPU substrate suppress the crack formation by providing smooth surface and reliable binding with stretchable layers. Also, the atomized liquid metal enables finely patterned top electrodes with a thin layer. In addition, by visualizing the stress distribution of the multi-layer structure, we have demonstrated that the systematic design and choices of suitable materials play an important role in implementation of our SOSCs that go beyond the limits of materials. |
