We present the optical properties (such as refractive index, extinction coefficient) of four layer structures, which differ only in the azo dyes layer. We used the family of azo compounds, where electron-donating and electron withdrawing groups (OCH3, CH3, Br) were introduced to the benzene ring. Then, these azo dyes were mixed with poly(3octylthiophene) (P3OT). Afterwards, the layered structure (i.e. glass/ITO/PEDOT:PSS/azo dye+P3OT) was produced. We found that by changing the substituent in the azo compound we change the photo-physical properties of multilayer structure. Thus, we can prepare layered structures that can have potential applications in optoelectronics as photovoltaic cells or organic light-emitting diodes.
