The cis - and trans -orientation of benzo[1,2- b :4,5- b ′]dithiophene-based isomers in organic solar cells
This work provides new insight into the backbone configurations of A-D-A-type acceptors. Two isomers have significant difference in optical and electric properties, resulting in a major impact on the current density and fill factor of the devices.
