A promising energy source for many current and future applications is a ribbon-like device that could simultaneously harvest and store energy. Due to the high flexibility and weavable property, a fabric/matrix made using these ribbons could be highly beneficial for powering wearable electronics. Unlike the approach of using two separate devices, here we report a ribbon that integrates a solar cell and a supercapacitor. The electrons generated by the solar cell are directly transferred and stored on the reverse side of its electrode which in turn also functions as an electrode for the supercapacitor. When the flexible solar ribbon is illuminated with simulated solar light, the supercapacitor holds an energy density of 1.15 mWh cm and a power density of 243 mW cm. Moreover, these ribbons are successfully woven into a fabric form. Our all-solid-state ribbon unveils a highly flexible and portable self-sufficient energy system with potential applications in wearables, drones and electric vehicles.
一种有前途的能源来源，适用于许多当前和未来的应用，是一种带状设备，它可以同时收集和存储能量。由于其高灵活性和可编织性，使用这些带子制成的织物/基质对于为可穿戴电子产品供电非常有益。与使用两个单独设备的方法不同，在这里我们报告了一种集成太阳能电池和超级电容器的带状物。太阳能电池产生的电子被直接转移并存储在其电极的背面，该电极反过来也用作超级电容器的电极。当柔性太阳能带被模拟太阳光照射时，超级电容器的能量密度为 1.15mWhcm，功率密度为 243mWcm。此外，这些带子成功地编织成织物形式。我们的全固态带状物展示了一种高度灵活和便携的自给自足能源系统，具有在可穿戴设备、无人机和电动汽车中的潜在应用。
