Abstract
A volatile solid additive strategy, which can effectively optimize the morphology of the photoactive layer with an ideal domain size and purity, has emerged as a promising approach to improve the photovoltaic performance of organic solar cells (OSCs). However, the precise role of solid additives in modulating charge and exciton dynamics, especially the recombination process, remains not fully understand. In this study, a solid additive, 1,4-diiodo-2,5-dimethoxybenzene (DIDOB), is developed to improve the photovoltaic performance of OSCs and conduct a comprehensive investigation into its effect on the charge recombination process. As a result, the PM6:L8-BO-X-based binary OSC processed with DIDOB achieves an…
