Overview

This research shows enhanced thermoelectric properties in PBFDO films through FeCl3 and DMSO treatment, indicating potential for n-type materials.

Key Points

  • The optimal power factor of the treated polymer reached 306.1 µW m−1 K−2, outperforming existing n-type materials.
  • Enhancements in the Seebeck coefficient and electrical conductivity were observed, reaching values of -56.2 µV K−1 and 970 S cm−1 respectively.
  • FeCl3 treatment with DMSO solvent plays a crucial role in improving the polymer's thermoelectric properties.
  • The achieved ZT value of 0.27 at room temperature indicates significant potential for practical thermoelectric applications.
