Indoor photovoltaic (IPV) with power output over 100 μW is promising to power the numerous sensor nodes in the Internet of Things (IoT) ecosystem. All polymer photovoltaic has the advantages of excellent thermal stability and superior mechanical properties. In this work, we fabricate the first all-polymer indoor photovoltaic module with the active area of 10 cm². The module uses polymer donor CD1 and new polymer acceptor PBN-21 with medium optical band gap of 1.9 eV as the active layer. It is processed with eco-friendly solvent tetrahydrofuran and the morphology can be improved by blade coating at 55°C. Under light emitting diode illumination at 1000 lux, the module exhibits a power conversion efficiency of 12.04% and a power output of 367.2 μW. The sufficient power output, high efficiency, excellent stability, and eco-friendly processing indicate that all-polymer indoor photovoltaic is a promising approach to achieve the self-powered of sensor nodes in the IoT ecosystem.

功率输出超过 100 μW 的室内光伏 (IPV) 有望为物联网 (IoT) 生态系统中的众多传感器节点供电。全聚合物光伏具有优异的热稳定性和优越的机械性能等优点。在这项工作中，我们制造了第一个有效面积为10 cm ²的全聚合物室内光伏组件。该模块采用聚合物给体CD1和新型聚合物受体PBN-21（中等光学带隙为1.9 eV）作为有源层。采用环保溶剂四氢呋喃加工，55℃下刮涂可改善形貌。在1000勒克斯的发光二极管照明下，该模块的功率转换效率为12.04%，功率输出为367.2μW。充足的功率输出、高效率、优异的稳定性和环保的处理表明全聚合物室内光伏是实现物联网生态系统中传感器节点自供电的一种有前途的方法。
