Herein, we report integrated photo-rechargeable supercapacitors (IPSs) composed of the inverted organic solar cell (iOSC) and solid-state supercapacitor (SC), enabling a high-performance self-power pack. The iOSC serves as a self-power source while the SC functions as energy storage, and both share an indium-tin-oxide (ITO) electrode that affords improved charge propagation across the devices. Combining the energy harvesting and storage devices in this way significantly alleviates the limitations of each device. The power fluctuation of the iOSC can be reimbursed by the SC, thus allowing for a stable energy output. Moreover, the SC is frequently charged by the iOSC during the daytime, thereby greatly reducing the charging time and avoiding a complete discharge as well. When the SC of the IPS is charged by the iOSC under AM 1.5 G of illumination, the overall energy conversion-storage efficiency is ca. 2.27%. Our work provides an effective strategy for further study to fabricate a small, lightweight, portable/wearable self-power pack by integrating energy harvesting and energy storage devices into a single structure.

本文中，我们报告了由反向有机太阳能电池（iOSC）和固态超级电容器（SC）组成的集成式可充电超级电容器（IPS），可实现高性能的自供电。iOSC用作自供电，而SC用作能量存储，并且都共享一个氧化铟锡（ITO）电极，从而改善了电荷在整个器件中的传播。通过这种方式组合能量收集和存储设备，可以大大减轻每个设备的局限性。SC可以补偿iOSC的功率波动，从而实现稳定的能量输出。此外，在白天，iOSC经常为SC充电，从而大大减少了充电时间，也避免了完全放电。当iOSC在AM 1.5 G照明下为IPS的SC充电时，总能量转换-存储效率约为。2.27％。通过将能量收集和能量存储设备集成到单个结构中，我们的工作为进一步研究制造小型，轻便，便携式/可穿戴式自供电组件提供了有效的策略。
