Converting solar energy into electricity is highly appealing for portable wearable devices. Herein, an facile low-temperature in situ interface polymerization is proposed to fabricate poly (3,4-ethylene dioxythiophene) (PEDOT)-based polyacrylonitrile (PAN) nanofiber film (PAN-PEDOT). Owing to the synergy of PEDOT and fabric light traps, the fabricated PAN-PEDOT owns excellent photo-thermoelectric performances with a power factor of ~256.61 nWm⁻¹ k⁻². Accordingly, a photo-thermoelectric harvester assembled by the optimum PAN-PEDOT strip and the copper wires reached a 0.17 mV voltage output under infrared (IR) light. Furthermore, a flexible textile solar panel assembled using the optimum PAN-PEDOT and the conductive nanofiber films were placed under an IR lamp and sunlight to investigate its performance in on-body applications. Results showed that the solar panel can obtain a voltage outputs of 1.39 mV and 0.56 mV and a power outputs of 0.37 nW and 0.06 nW under an IR lamp and sunlight, respectively. Therefore, the photo-thermoelectric fabric has high potential in solar-to-heat and solar-to-electricity applications.

将太阳能转化为电能对便携式可穿戴设备非常有吸引力。在此，提出了一种简便的低温原位界面聚合来制备聚（3,4-乙烯二氧噻吩）（PEDOT）基聚丙烯腈（PAN）纳米纤维膜（PAN-PEDOT）。由于 PEDOT 和织物光阱的协同作用，制备的 PAN-PEDOT 具有优异的光热电性能，功率因数为 ~256.61 nWm ^-1 k ^-2. 因此，由最佳 PAN-PEDOT 条和铜线组装的光电采集器在红外 (IR) 光下达到 0.17 mV 电压输出。此外，将使用最佳 PAN-PEDOT 和导电纳米纤维膜组装的柔性纺织太阳能电池板放置在红外灯和阳光下，以研究其在身体应用中的性能。结果表明，太阳能电池板在红外灯和阳光下分别可以获得1.39 mV和0.56 mV的电压输出和0.37 nW和0.06 nW的功率输出。因此，光热电织物在太阳能热和太阳能发电应用中具有很高的潜力。
