Paper-based substrates have been increasingly attractive in flexible electronics technology as flexible support substrates due to their advantages of availability, environmental friendliness (as disposable, degradable, and renewable materials), and foldability. Hereby, a facile method for installation of p-type and n-type semiconductor legs in the thickness direction of a paper substrate was established. A transparent paper-based thermoelectric generator prototype by impregnating the paper with resin was then fabricated. The resulting transparent paper-based thermoelectric generator with 10 thermocouples showed excellent mechanical flexibility. The generator maintained a maximum voltage and an output power of ∼8.3 mV and ∼10 nW, respectively, at a temperature difference of 35 K after 1000 bending cycles. This work offers a promising strategy for the development of paper-based thermoelectric generators that are adaptable to a wide variety of complex curved surface heat source. Therefore, the heat recovery efficiency in both human and natural environments can be greatly improved.
基于纸张的基底由于其可用性、环境友好性（作为一次性、可降解和可再生材料）和可折叠性，在柔性电子技术中作为柔性支撑基底越来越受到关注。因此，建立了一种在纸张基底厚度方向上安装 p 型和 n 型半导体腿的简便方法。然后通过将纸张浸渍在树脂中制造了透明的基于纸张的热电发生器原型。由 10 个热电偶组成的所得透明基于纸张的热电发生器具有出色的机械柔韧性。在经过 1000 次弯曲循环后，在 35 K 的温差下，该发生器保持最大电压和输出功率约为 8.3 mV 和 10 nW。这项工作为适应各种复杂曲面热源的基于纸张的热电发生器的发展提供了一种很有前途的策略。因此，可以大大提高人类和自然环境中的热回收效率。
