Abstract

Abstract : 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 ( V oc ) 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 (PC61 BM) system ( V oc = 0.59 V, FF = 0.57, and PCE = 3.34%).
