Herein, the synthesis of two novel (X‐DADAD) n conjugated polymers comprising phenylene or fluorene X blocks coupled with benzothiadiazole acceptor (A) and thiophene donor (D) units is reported. The designed polymers are explored as absorber materials in organic solar cells and hole‐transport materials (HTMs) in perovskite solar cells (PSCs). The encouraging efficiencies of ≈ 17% are obtained in PSCs when using fluorene‐containing polymer P2 featuring this material as a promising HTM for the state‐of‐the‐art perovskite photovoltaics.
