Insights into the Physical Characteristics of Spin Coating Films of Organometallic Materials Based on Phthalocyanine with Nickel, Copper, Manganese and Silicon

High-performance organometallic materials based on phthalocyanine (Pc) thin films with nickel, copper, manganese and silicon were deposited onto glass substrates using spin-coating technique at room temperature. The physical properties of the films were characterized to evaluate the influence of the dopant metal on their performance. Various analytical techniques, including X-ray diffraction analysis (XRD), Raman spectroscopy (RS), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and ultraviolet–visible transmittance spectroscopy, were employed to investigate the characteristics of the prepared films. For every sample, the produced films showed amorphous structure and crystallization. Analyses using XPS were done. It was discovered that there are three peaks in the composite C1s X-Pc signal, which is relevant to the interpretation of the main C1s signal. Analysis of SEM images revealed a uniform, dense, and homogeneous structure in the films, with minimal pores and microcracks. Optical analysis showcased remarkable visible-range optical absorption and an optical direct band gap ranging from 3.15 to 3.72 eV, along with exceptional transmission properties. The comprehensive exploration of the physical and optical characteristics of these phthalocyanine films positions the material as a promising candidate for advancements in solar cell technology, paving the way for potential breakthroughs in innovative and efficient solar energy applications.
