To enhance the photovoltaic properties of organic solar cells utilizing vinylene-bridged bis(difluoroquinoxaline) (FQxE)-terthiophene copolymers, we synthesized new FQxE-based polymers featuring diverse solubilizing groups. Furthermore, we examined the effect of alkyl side chain length on the physicochemical properties, thin-film structure, and photovoltaic performance in non-fullerene organic solar cells.
