Abstract
Two isoindigo-based small molecules were synthesized with 3-ethylrhodanine (RH) and ethyl cyanoacetate (ECA) dye end groups to use as acceptors in organic photovoltaic cells. The optical, electrochemical, and photovoltaic properties of the small molecules varied according to the electron accepting dye groups. ISDT-ECA had a better power conversion efficiency of 0.53% compared to ISDT-RH (0.42%) mainly due to the high-lying LUMO level and thus the higher open-circuit voltage of the ISDT-ECA.
