In situ polymerized PEDOT is used as hole‐transporting material to fabricate dye‐sensitized solar cells (DSSCs) with an average efficiency of 6.1% (under 100 mW cm −2 AM1.5 illumination) using organic D149 dye as the sensitizer. By comparing with Z907‐based devices, the excellent light response of D149‐sensitized DSSCs is attributed to the broad light absorption, low photoelectron recombination, and good polymer penetration.
