A detailed study of hitherto unknown electrical and thermoelectric properties of graphite pencil traces on paper was carried out by measuring the Hall and Seebeck effects. We show that the combination of pencil-drawn graphite and brush-painted poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) films on regular office paper results in extremely simple, low-cost, and environmentally friendly thermoelectric power generators with promising output characteristics at low-temperature gradients. The working characteristics can be improved even further by incorporating n-type InSe flakes. The combination of pencil-drawn n-InSe:graphite nanocomposites and brush-painted PEDOT:PSS increases the power output by 1 order of magnitude.
我们通过测量 Hall 和 Seebeck 效应，对纸上石墨铅笔痕迹迄今为止未知的电学和热电性质进行了详细研究。研究表明，普通办公纸上的铅笔绘制石墨和刷涂聚（3,4-乙撑二氧噻吩）聚苯乙烯磺酸盐（PEDOT：PSS）薄膜的组合产生了极其简单、低成本和环保的热电发电机，在低温梯度下具有有前景的输出特性。通过掺入 n 型 InSe 薄片，可以进一步改善其工作特性。铅笔绘制的 n-InSe：石墨纳米复合材料和刷涂的 PEDOT：PSS 的组合将功率输出提高了一个数量级。
