Benzothiadiazole-based non-fullerene acceptors

Qingling Nie et al.

Summary: The power conversion efficiencies of organic solar cells have been greatly improved with the rapid development of non-fullerene acceptors in recent years, especially using benzothiadiazole as an important electron-accepting unit. By judicious molecular engineering, the optoelectronic properties of BT-based small molecules can be efficiently modulated to achieve high-efficiency photovoltaic devices. The highest PCE reached up to 18% due to the emergence of fused-BT-based molecule Y6, which has promoted the rapid progress of OSCs since 2019.
