Implication

Novel solid additives improved film morphology in non-fullerene solar cells, highlighting electrostatic regulation.

Abstract

Two novel volatile solid additives, 2-bromo-1,3,5-trichlorobenzene (TCBB-1) and 3,4,5-trichlorobromobenzene (TCBB-2), are introduced into PM6:L8-BO non-fullerene systems to regulate film nano-morphology, which can be controlled by strong, electrostatically driven interactions. DFT-derived...
