摘要：
Poly(3-hexyl thiophene) (P3HT) can be easily synthesized, demonstrating the large potential to decrease the cost in large-scale synthesis. Thus, the development of novel non-fullerene acceptor to match well with P3HT is urgent and necessary. The first benzotriazole-containing non-fullerene acceptor is designed and synthesized, and high open-circuit voltage (Voc) of 1.02 V, fill factor (FF) of 0.70, and power conversion efficiency (PCE) of 5.24% are realized, which are remarkably higher than that of P3HT: [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) system (Voc = 0.59 V, FF = 0.57, and PCE = 3.34%).
