Abstract
A low band gap conjugated polymer derived from alkylthieno-2-yl flanked dithieno[2,3-d:2′,3′-d′]benzo[1,2-b:4,5-b′]dithiophene and a naphtho[1,2-c:5,6-c]bis[1,2,5]thiadiazole derivative was first synthesized, and high performance inverted photovoltaic solar cells with a power conversion efficiency of 7.52% have been demonstrated.
