BODIPY‐Coumarin Triad as Acceptor for Ternary Nonfullerene Solar Cells with over 15% Efficiency

Year: 2025

Type: article

Abstract: Herein, a new nonfused fullerene-free acceptor is synthesized based on the BODIPY-coumarin triad, BDP-2C, which exhibits a medium optical bandgap of about 1.51 eV, and HOMO and LUMO energy levels of about -5.50 and -4.00 eV, respectively. Employing BDP-2C as a guest component in PM6:Y6, the resulting optimized ternary organic solar cells (OSCs) attained a power conversion efficiency (PCE) of about 15.09% with a low energy loss of 0.503 eV. The balanced charge transport and suppressed charge recombination, shorter charge extraction time, and prolonged charge carrier lifetime are the factors that enhance the PCE of ternary OSCs.
