Synthesis and characterization of chiral nano-poly [(±)-2-sec-butyl aniline] via FeCl3.6H2O as an oxidant and investigation of its application in the first chiral solar cell

A chiral derivative of polyaniline, poly [(±)-2-sec-butyl aniline] (PSBA), was successfully synthesized. The polymerization is carried out by oxidative polymerization of (±)-2-sec-butyl aniline in the presence of FeCl3.6H2O under both solid (solvent-free) and solution state conditions. Several techniques used to characterize the polymers, such as; ultraviolet-visible (UV-vis) spectroscopy, Fourier-transform infrared (FT-IR), Dr. Blade s method was used to construct polymer solar cells with a structure such as FTO/TiO2/1/Al, FTO/TiO2/2/Al, FTO/TiO2/3/Al and FTO/TiO2/4/Al. The PCE (power conversion efficiency) of the FTO/TiO2/1/Al, FTO/TiO2/2/Al, FTO/TiO2/3/Al and FTO/TiO2/4/Al samples were 0.36, 0.21, 0.32 and 0.16%, respectively. The advantages of our solar cell are simple structure (single layer), easy to fabricate, fewer fabrication costs, green synthesis condition, and the high stability of the resulted cells
