Abstract: Thermoelectric materials are a new type of material that can convert thermal energy and electrical energy into each other, and play an important role in waste heat recovery, energy conservation and protection. With the development of thermoelectric materials, compared with inorganic thermoelectric materials, organic thermoelectric materials have received great attention due to their advantages of light weight, no pollution, and easy access to raw materials. With the development of thermoelectric materials, organic thermoelectric materials have received great attention due to their advantages of light weight, no pollution, and easy access to raw materials. This paper reviews the research progress of organic thermoelectric materials in recent years, the problems that need to be solved urgently and the future development direction of organic thermoelectric materials. A large number of literatures and studies have shown that the performance of organic thermoelectric materials needs to find suitable dopant doping, rational design of molecular chain skeleton, and the search for suitable inorganic fillers to improve. Organic thermoelectric materials will have a long road to explore, and will face more opportunities and challenges in the future.
