PBQx-TF, high efficiency narrow bandgap copolymer

Single junction non-fullerene polymer PBQx-TF solar cells gives efficiency of close to 19%

PBQx-TF is a highly efficient semiconducting polymer donor based on electron donating benzo[1,2-b:4,5-b']dithiophene (BDT) and electron withdrawing dithieno[3,2-f:2',3'-h]quinoxaline (DTQx) units as the main backbone, bearing two 2-ethylhexyl-3-fluorothiophene side chains on the fused BDT ring and 2-butyloctyl solubilising groups on the bridging thiophen rings.

Single junction non-fullerene polymer solar cells based on PBQx-TF as the electron donor and eC9-2Cl:F-BTA3 as the binary electron acceptors in the active layer achieved a PCE of 19% with an open-circuit voltage of 0.879 V, short-circuit current density of 26.7 mA cm-2, and fill factor of 0.809. The device had the following structure [1].

Device structure: ITO/PEDOT:PSS/PBQx-TF:eC9-2Cl:F-BTA3 (1:1:0.2)/PNDIT-F3N-Br/Ag
