Organic thermoelectric (TE) materials capitalize on advantages such as low thermal conductivity, low-cost, eco-friendly, versatile processability, light-weight, mechanical flexibility, roll-to-roll production, which are advantageous for the development of portable and wearable self-powered electronics. On the negative side, the figure-of-merit of polymer TE materials is low, mainly owing to typical low electrical conductivity. Various efforts have been made to enhance the TE performance of organic TE materials, i.e. chemical or electrochemical doping, modification of molecular structure, and fabrication of polymer-based composites or blends, which is the simplest and most cost-effective method for modifying polymer properties. Solution-processed polymer/inorganic or organic hybrids pave the way for formulation of functional TE inks/paste which can be used to fabricate large scale cost-effective manufacturing of TE generators. In this review, we briefly summarize the TE properties of conjugated polymers, and focus on recent developments in polymer/carbon nanofillers (e.g. CNT, graphene, GO) composites and polymer/inorganic TE nanoparticles composites along with preparation methods and thermoelectric performance. Finally, we cover recent advances in the development of functional TE inks, processing techniques, and their usage in device fabrication using various printing techniques and review device output characteristics.

有机热电（TE）材料利用了诸如低导热率，低成本，环保，通用的可加工性，重量轻，机械柔韧性，卷对卷生产等优点，这些优点有利于便携式和可穿戴设备的发展自供电电子产品。不利的一面是，品质因数主要由于典型的低电导率，聚合物TE材料的制造成本低。为了提高有机TE材料的TE性能，已进行了各种努力，即化学或电化学掺杂，分子结构的改性以及基于聚合物的复合材料或共混物的制造，这是最简单且最具成本效益的改变聚合物性能的方法。 。溶液加工的聚合物/无机或有机杂化物为功能性TE油墨/糊料的配制铺平了道路，可用于制造经济高效的TE发生器大规模生产。在这篇综述中，我们简要概述了共轭聚合物的TE特性，并将重点放在聚合物/碳纳米填料（例如CNT，石墨烯，GO）复合材料和聚合物/无机TE纳米颗粒复合材料以及制备方法和热电性能。最后，我们介绍了功能性TE墨水，处理技术及其在使用各种印刷技术的设备制造中的使用情况的最新进展，并回顾了设备的输出特性。
