Abstract

Novel n-type materials of BTD-CN (1) and BTD-CF₃ (2) were synthesized for organic photovoltaics. Both materials show approximately the same HOMO-LUMO level and position of absorption peaks. However, the organic photovoltaic performance of a device with 1 is clearly higher than that with 2. In this paper, we discuss the effects of terminal substituents on film morphology, crystallinity, and photovoltaic performance. The results suggest that cyano-modified benzothiadiazole is useful because of its crystallinity, carrier recombination, and series resistance.
