A₂–A₁–D–A₁–A₂ type non-fullerene acceptors based on methoxy substituted benzotriazole with three different end-capped groups for P3HT-based organic solar cells

Abstract

In the last three years, the A₂–A₁–D–A₁–A₂ skeleton has become increasingly popular in the design of non-fullerene acceptors (NFAs), and it could match particularly well with the classic p-type polymer of poly(3-hexylthiophene) (<bold>P3HT</bold>).
