Materials, Organic Conductors, Semiconducting Molecules, Small Molecule OPV Donors
It is believed that the extended A-π-D-π-A conjugation and planar structure of ZR1 can enhance the charge carrier mobility, reduce the conformational disorder of the backbone, and also increase the molecular planarity to facilitate electron delocalization in packed films. Using 3-octyl-2,2'-bithiophene as the π-bridge deepens the HOMO level and increases the molecular rigidity.
The UV-Vis absorption edge of the ZR1 is located at ca. 675 nm in chloroform processed as-cast thin film, corresponding to a medium optical bandgap of 1.84 eV. A binary all-small-molecule simple structured organic solar cells obtained the highest efficiency of 14.34% with ZR1 as the small molecule donor and NFAs Y6 as the NFA.
