dc.description.abstract | Organic thermoelectrics have attracted considerable attention owing to their remarkable advantages, including roomtemperature power generation, skin-attachable/wearable applications with biocompatibility, and solution-based high-throughput fabrication. Self-doped conjugated polyelectrolytes (CPEs) constitute a promising class of conductive organic materials that are considered potential candidates for organic thermoelectrics. However, the low power factor of CPEs derived from their low electrical conductivity (sigma) has been a major drawback in CPE-based thermoelectrics. Herein, we report a strategy for enhancing the thermoelectric performance of CPEs through post-treatment using aq H2SO4 solution. The post-treatment increases sigma by 2 orders of magnitude, originating from H2SO4-induced doping accompanying a significant increase in charge-carrier concentration. Consequently, a power factor of 3.0 mu W m(-1) K-2 is achieved at room temperature. Furthermore, using this highly conductive H2SO4-doped CPE, we developed flexible thermoelectric generators that allow durable power generation under repetitive mechanical bending stresses. Our findings provide insight into developing high-performance and versatile CPEs for the next-generation organic thermoelectrics. | - |
