A fused-ring based electron acceptor for efficient non-fullerene polymer solar cells with small HOMO offset


A non-fullerene electron acceptor bearing a novel backbone with fused 10-heterocyclic ring (indacenodithiopheno-indacenodiselenophene), denoted by IDTIDSe-IC is developed for fullerene free polymer solar cells. IDTIDSe-IC exhibits a low band gap (Eg=1.52 eV) and strong absorption in the 600–850 nm region. Combining with a large band gap polymer J51 (Eg=1.91 eV) as donor, broad absorption coverage from 300 nm to 800 nm is obtained due to complementary absorption of J51 and IDTIDSe-IC, which enables a high PCE of 8.02% with a VOC of 0.91 V, a JSC of 15.16 mA/cm2 and a FF of 58.0% in the corresponding PSCs. Moreover, the EQE of 50–65% is achieved in the absorption range of IDTIDSe-IC with only about 0.1 eV HOMO difference between J51 and IDTIDSe-IC.
