ABSTRACT Photovoltaic cells are crucial for harnessing solar energy and converting it into usable electrical power. This research focuses on the development of D‐A type polymer cell acceptors based fluorinated phenazine. We synthesized four distinct polymers: PBDT‐DT‐DoDFPz PBDTT‐DT‐DoDFPz with linear alkyl side chains, PBDT‐DT‐DHDFPz PBDTT‐DT‐DHDFPz branched chains. The polymers PBDTT‐DT‐DHDFPz, incorporating BDTT, showed deeper HOMO levels than PBDT‐DT‐DHDFPz, which feature BDT. Additionally, phenazine units in resulted lower compared to PBDTT‐DT‐DoDFPz, enhancing open‐circuit voltage (Voc). AFM imaging revealed that chains formed more uniform smaller domains when DCB was used, while demonstrated better domain uniformity a 3% DIO additive. final device optimization yielded short‐circuit current density (J_sc) 9.36 mA/cm 2 , V_oc 0.66 V, an FF 0.55%, resulting maximum PCE 3.41%.
