Abstract : This work focuses on the fabrication, characterization, and understanding of some physical properties of palladium(II) phthalocyanine (PdPc) thin films. PdPc was synthesized and deposited by vacuum thermal evaporation on glass, indium–tin oxide (ITO)/glass, and fluorine-doped tin oxide (FTO)/glass substrates. The optical properties of the films were investigated from transmittance measurements in the wavelength range of 200–1800 nm. The optical absorption data directly yielded the bandgap energy. The dispersion of the refractive index was analyzed in terms of the Wemple– DiDomenico single effective oscillator model. The optical bandgap E g , dispersion energy E d , single oscillator energy E 0 , and optical constants such as refractive index, extinction coefficient, dielectric constant, and optical conductivity were estimated. The experimental results revealed that the substrate played a significant role in the structural and the optical properties of the deposited palladium phthalocyanine thin films, and these films would be suitable for application in organic solar cells. Keywords- Palladium phthalocyanine (PdPc), Thin films, Thermal evaporation, Substrates, Wemple–Didomineco model.
