Synergistically optimizing the optoelectronic properties and morphology using a photo-active solid additive for high-performance binary organic photovoltaics

Abstract

This work explores a new solid additive with TADF properties for high-performance OPVs. The TADF additive fine-tunes the morphology and enhances exciton diffusion and dissociation, resulting in an efficiency of 19.4%, making it one of the top binary OPVs.
