自充电电源组在微系统中具有巨大的应用潜力，但这些电路在实际应用中，特别是在可穿戴和便携式电子产品中，需要便携、轻便甚至无线连接。在这项研究中，我们报告了无线便携式轻型溶液处理自充电电源包，该电源包由串联太阳能电池通过溶液处理导电聚合物薄膜与固态非对称超级电容器集成而成。最后，我们首先开发了钙钛矿太阳能电池（PSCs）与三元有机太阳能电池（OSCs）结合的溶液处理串联太阳能电池，以实现大的工作电压。为了提高能量密度和循环稳定性，我们利用新型正极和固态聚合物电解质开发了固态非对称超级电容器。然后，我们将PSCs-OSCs串联太阳能电池与固态非对称超级电容器通过溶液加工导电聚合物薄膜集成，构建无线便携式轻重量溶液加工自充电电源组。这种新型自充电电源包不仅具有便携、轻便、无线连接等先进特点，而且具有优良的电路器件性能，在白光照明下总效率为12.43%，储能效率为72.4%。以上结果表明，首次研制出以串联太阳能电池为可再生能源，以固态非对称超级电容器为储能装置，与溶液处理导电聚合物薄膜连接的无线便携式轻量化自充电电源包。
Self-charging power packs possess great potential applications in the micro-systems, but these electric circuits are required to be portable, light-weight and even wireless connected for practical applications, in particular, in the wearable and portable electronics. In this study, we report wireless portable light-weight solution-processed self-charging power packs by tandem solar cells integrated with solid-state asymmetric supercapacitors through solution-processed electrical conductive polymeric thin film. Towards the end, we first develop solution-processed tandem solar cells by perovskite solar cells (PSCs) combined with ternary organic solar cells (OSCs) for achieving large operational voltage. We then develop solid-state asymmetric supercapacitors by both novel positive electrode and solid-state polymeric electrolytes for enhancing the energy density and cycling stability. After that, we integrate PSCs–OSCs tandem solar cells with solid-state asymmetric supercapacitors through solution-processed electrical conductive polymeric thin film to build wireless portable light-weight solution-processed self-charging power packs. This novel self-charging power packs not only possess advanced features such as portable, light-weight and wireless connection, but also exhibit excellent electric-circuit device performance, such as with an overall efficiency of 12.43% and an energy storage efficiency of 72.4% under white light illumination. All these results demonstrate that the wireless portable light-weight self-charging power packs through utilization of tandem solar cells as the renewable energy source and solid-state asymmetric supercapacitors as the energy storage device connected with solution-processed electrical conductive polymeric thin film, for the first time, are developed.
