Abstract:
Given the effectiveness of organic pollutants photodegradation and the excellent photovoltaic nature of organic solar cells (OSCs), this work first innovatively integrated the cross-fields of OSCs and environmental photocatalysis. Using knowledge of OSC morphology, an insertion strategy involved adding a suitable quantity of guest acceptor (Y6-O) to the PM6 donor polymer and BTP-2F-ThCl host small molecule acceptor system. Y6-O leads to tighter π-π packing, reduced domain size, and improved domain purity, resulting in favorable morphology for charge generation and transfer in devices and an improved power conversion efficiency (PCE) from 17.1% to 18.1%. Moreover, terpolymer organic photovoltaic films were applied to wastewater treatment, gaining ions Sb(III) and Sb(V) removals of 100% in 15 min, and guaiacol photodegradations of 90% in 1 h. This work significantly prompts the development of organic photovoltaics and wastewater treatment and opens views for multifunctional organic photovoltaic material applications.
