摘要

In this work

a novel solid additive BBT-Cl was introduced into organic solar cells (OSCs) based on PM6:Y6. By combining BBT-Cl with traditional solvent additive 1-chloronaphthalene (CN)

the OSCs processed by the dual additives exhibit an excellent power conversion efficiency (PCE) and stability

which indicating the potential of solid additive in achieving high-performance OSCs.

Abstract

The use of additive is an effective approach to optimize the active layer morphology and improve the power conversion efficiency (PCE) of organic solar cells (OSCs). However

residual solvent additives always lead to undesirably compromise the stability of OSCs. In this work

an organic small molecule BBT-Cl was designed and used as a novel solid additive to partly replace solvent additive to fabricate high-performance OSCs. The synergistic effect of the dual additives on the optical property

morphology and photovoltaic characteristics of the PM6:Y6 based non-fullerene OSCs have been systematically characterized. The introduction of BBT-Cl could effectively enhance the crystallinity of the blend and promote charge extraction and transport. Consequently

the OSCs processed by the dual additives exhibit a high PCE of 17.73%

which is obviously higher than OSCs with CN additive (16.48%). Meanwhile

BBT-Cl based dual additives treatment has also been successfully introduced into another two non-fullerene OSCs to verify its general applicability. Furthermore

20% PCE aging is significantly prolonged from 720 min to 2880 min for the devices proceeded with the dual additives. This work highlights the great potential of solid additive in the fabrication of efficient OSCs with excellent stability.
