Joints widely exist in traditional organic electronic devices that are composed of p–n modules, including organic thermoelectric (TE) devices. They often harm the performance of the devices by increasing their electrical resistance and thermal resistance. Recently, a few joint-free approaches have been reported to fabricate TE devices with a single carbon nanotube (CNT) composite film. However, the resolution of p–n patterns is low, e.g., >100 μm, with a conventional printing/drop-casting method. Herein, a plasma treatment method was reported to fabricate joint-free TE devices with a single-piece flexible CNT composite film whose performance was higher than that of traditional devices in energy harvesting and solid-state cooling. In addition, this method provided p–n patterns with a high resolution of ∼1–2 μm which is promising for making future high integration level TE devices. This method can be extended to fabricate a broad range of high integration level organic electronic devices composed of p–n modules.

具有用于能量收集和固态冷却的超高分辨率 p-n 模式的无接头单件柔性热电器件

接头广泛存在于由 p-n 模块组成的传统有机电子器件中，包括有机热电 (TE) 器件。它们通常会通过增加电阻和热阻来损害设备的性能。最近，已经报道了一些无接头方法来制造具有单碳纳米管 (CNT) 复合膜的 TE 器件。然而，使用传统的印刷/滴铸方法，p-n 图案的分辨率较低，例如 >100 μm。在此，据报道，一种等离子体处理方法可以制造具有单片柔性 CNT 复合膜的无接头 TE 器件，其在能量收集和固态冷却方面的性能高于传统器件。此外，这种方法提供了分辨率约为 1-2 μm 的 p-n 图案，这有望用于制造未来的高集成度 TE 器件。这种方法可以扩展到制造各种由 p-n 模块组成的高集成度有机电子器件。
