| 논문초록 | Stretchable organic solar cells (SOSCs) are attracting considerable attention for wearable electronics, including biosensors, electronic skins, and stretchable displays. Although SOSCs possess promising properties such as high power-per-weight output and strong durability under repetitive tensile strains, they remain proof of concept, as they do not satisfy the required performance for wearable electronics. Reconciling high power conversion efficiency (PCE) and reasonable stretchability is a difficult task. This study reports highly efficient and intrinsically SOSCs by integrating multiple stretchable layers with strong bindings. Our SOSC has reached the highest efficiency of 11.2% PCE, the highest as far as we know, with remarkable stretchability; it also maintained over 74% of the initial PCE when subjected to 10% strain for 1,000 cycles.
