In this research, chiral copolymers were synthesized using ۲-sec-butylaniline, ۲-Aminobenzene sulfonic acid, and ۳-aminobenzene sulfonic acid monomers in the presence of FeCl۳.۶H۲O as an oxidant. Their application in polymer solar cells were investigated, and the maximum efficiency was ۱.۲۳%. The synthesized compounds were characterized using FT-IR spectroscopy. The optical properties of the synthesized compounds were investigated by UV-vis spectroscopy. The electrochemical behaviour of the synthesized copolymers was investigated by cyclic voltammetry.
