Terpolymers consisting of three different monomers in the polymer backbone have emerged as promising p-type polymers for polymer solar cells (PSCs). The incorporation of a third monomer into a donor-acceptor (D-A) copolymer backbone can create numerous combinations that may have a synergetic effect on physicochemical properties such as light harvesting ability, miscibility, charge carrier mobility, energy levels and crystallinity. Moreover, the random arrangement of terpolymer can reduce the degree of regularity in the polymer backbone, thereby enabling high solubility in non-halogenated solvents. However, despite the various merits, terpolymer-based PSCs processed with non-halogenated solvents still have shown poor photovoltaic performance and long-term stability. In this talk, I will present the synthesis and characterization of novel 1D/2A terpolymers composed of one donor and two acceptors for high-efficiency and long-lived PSCs processed with non-halogenated solvents. |
