This study investigates the enhancement of thermoelectric properties in conjugated polymers through suppression of dopant-induced disorder. By using ion-exchange doping, the researchers achieved high electrical conductivity (>400 S cm⁻¹) and power factor (>16 μW m⁻¹ K⁻²) in poly[(3HT)₁₋ₓ-stat-(T)] (P3), a random copolymer with x = 0.24. This performance surpasses that of P1 (P3HT), which has lower conductivity (<40 S cm⁻¹) and power factor (<4 μW m⁻¹ K⁻²). The study shows that ion-exchange doping minimizes structural disorder, leading to improved charge transport. GIWAXS measurements reveal that the in-plane π-π stacking distance in doped P3 is significantly shorter (3.44 Å) compared to doped P1 (3.68 Å), indicating better molecular packing and enhanced charge mobility. Hall effect measurements confirm that P3 has a higher Hall mobility (1.2 cm² V⁻¹ s⁻¹) than P1 (0.06 cm² V⁻¹ s⁻¹). The results demonstrate that ion-exchange doping effectively suppresses dopant-induced disorder, enabling fast charge transport in highly doped conjugated polymers. The study highlights the importance of minimizing structural disorder to achieve efficient organic electronics. The findings contribute to resolving long-standing issues in P3HT-based materials and provide a strategy for achieving high-performance thermoelectrics. The research also emphasizes the role of intermolecular packing and π-π stacking in enhancing charge transport properties. The study concludes that the energetic ordered landscape in highly IEx-doped P3 leads to high Hall mobility and electrical conductivity, significantly outperforming P3HT. The work offers an effective strategy for realizing fast charge transport in highly doped conjugated polymers and underscores the importance of overcoming dopant-induced disorder for next-generation organic electronics.This study investigates the enhancement of thermoelectric properties in conjugated polymers through suppression of dopant-induced disorder.
