Both flexible energy harvesting and storage devices have been widely reported separately to satisfy part of the needs in the emerging areas, including wearable electronics, and low-density applications such as rooftop solar collectors. However, a flexible energy system with mechanical robustness and light-weight is the integrated device that will serve the real demand. Herein, a flexible printable dye-sensitized solar cell/supercapacitor integrated energy device has been designed, fabricated and characterized. This new device has several advantages: flexible, portable, high voltage capacity (up to 1.8 V), lightweight, environmental friendly and expanded indoor-use capabilities. The device demonstrated very stable performances under various extreme mechanical loading conditions in outdoor testing. This work paves way for future development of highly flexible integrated energy system for many potential applications.

柔性能量收集和存储设备已被广泛报道，可以满足新兴领域的部分需求，包括可穿戴电子设备和低密度应用（如屋顶太阳能收集器）。但是，具有机械坚固性和重量轻的灵活能源系统是可以满足实际需求的集成设备。在此，已经设计，制造和表征了柔性的可印刷染料敏化太阳能电池/超级电容器集成能量装置。这种新设备具有以下优点：灵活，便携式，高压容量（最高1.8 V），轻巧，环保和扩展的室内使用能力。该器件在室外测试的各种极端机械负载条件下均表现出非常稳定的性能。
