However, achieving a balance between the Seebeck coefficient (\n                    <jats:italic>S<\/jats:italic>\n                    ) and electrical conductivity (\n                    <jats:italic>\u03c3<\/jats:italic>\n                    ) remains challenging. In this work, we employ thienoisoindigo (TIIG) as the acceptor and dithieno[3,2\u2010b:2',3'\u2010d]pyrrole (DTP) as the donor to construct two novel D\u2010A conjugated polymers for TE application. Through introducing thiophene (T) units as spacers between DTP and TIIG, PTIIG\u20102T\u2010DTP enhances the planarity of conjugated backbones compared to PTIIG\u2010DTP. Moreover, PTIIG\u20102T\u2010DTP film shows more compact packing between conjugated backbones, which improves the charge transport. Despite slightly lower doping efficiency, doped PTIIG\u20102T\u2010DTP exhibits superior carrier mobility and conductivity to PTIIG\u2010DTP. Additionally, PTIIG\u20102T\u2010DTP shows a higher Seebeck coefficient at same doping concentration. Ultimately, PTIIG\u20102T\u2010DTP achieves a large power factor of 23.2 \u00b5Wm\n                    <jats:sup>\u22121<\/jats:sup>\n                    K\n                    <jats:sup>\u22122<\/jats:sup>\n                    with\n                    <jats:italic>\u03c3<\/jats:italic>\n                    of 120 S cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    which is much higher than that of PTIIG\u2010DTP.
