Abstract The dual challenges of photocatalysis technology in addressing wastewater pollution and the energy crisis demand advanced photocatalysts with enhanced visible light absorption efficient charge separation. This work utilizes bulk‐heterojunction organic solar cell (BHJ‐OSCs) active layers as photocatalytic sources, presenting PM6:PIID‐ClBF@BC, a biochar‐supported donor‐acceptor (D‐A) heterojunction photocatalyst, designed for water phototreatment clarify impacts molecular structure on activity, simultaneously assist associated OSCs waste disposal resource secondary expansion. PM6:PIID‐ClBF@BC achieves complete RhB degradation within 10 minutes maintains nearly 100% over 20 cycles. Additionally, it generated 28.15 µmol H₂ 3 hours, corresponding to rate 187.67 h⁻¹ g⁻¹. superior performance is attributed its broader visible‐light absorption, increased electronegativity (enhanced dipole moment) induced by chlorine substitution, favorable stacking interactions provide larger electron delocalization, forming strong internal electric field that drives separation intramolecular transfer thereby enhancing reactive oxygen species generation. Electrostatic between facilitate effective adsorption catalysis, higher superoxide radical levels driving degradation. highlights crucial role optimizing performance, offering insights designing next‐generation environmental remediation sustainable energy.
