Abstract

PYIT was added to the PM6:Y6 system to delay and shorten the crystallization time of Y6. The ternary strategy has been successfully proven to increase the D/A interface area for faster exciton dissociation. The Eloss decreased (0.559 eV to 0.539 eV), and the PCE increased (15.40% to 17.05%).
