Synthesis and characterization of chiral nano-poly [(±)-۲-sec-butylaniline] via FeCl۳.۶H۲O as an oxidant and investigation of itsapplication in the first chiral solar cell

A chiral derivative of polyaniline, poly [(±)-۲-sec-butyl aniline] (PSBA), was successfully synthesized.The polymerization is carried out by oxidative polymerization of (±)-۲-sec-butyl aniline in the presenceof FeCl۳.۶H۲O under both solid (solvent-free) and solution state conditions. Several techniques used tocharacterize the polymers, such as; ultraviolet-visible (UV-vis) spectroscopy, Fourier-transforminfrared (FT-IR), Dr. Blade's method was used to construct polymer solar cells with a structure such asFTO/TiO۲/۱/Al, FTO/TiO۲/۲/Al, FTO/TiO۲/۳/Al and FTO/TiO۲/۴/Al. The PCE (power conversionefficiency) of the FTO/TiO۲/۱/Al, FTO/TiO۲/۲/Al, FTO/TiO۲/۳/Al and FTO/TiO۲/۴/Al samples were۰.۳۶, ۰.۲۱, ۰.۳۲ and ۰.۱۶%, respectively. The advantages of our solar cell are simple structure (singlelayer), easy to fabricate, fewer fabrication costs, green synthesis condition, and the high stability of theresulted cells.
