Thin CIGS Films Obtained by Spray Pyrolysis

This article presents the results of synthesizing polycrystalline CuIn(Ga)Se2 (CIGS) films using a combined spray pyrolysis method followed by additional selenization. The main focus is on analyzing the obtained films’ structural, morphological, and compositional characteristics by applying XRD, SEM, EDX, and Raman spectroscopy. XRD analysis confirmed the formation of a polycrystalline tetragonal chalcopyrite structure, while SEM and EDX analyses revealed a disordered morphology and high compositional uniformity. Raman spectroscopy emphasized the phase purity of the material. The results highlight the significant potential of the synthesized CIGS films in high-efficiency thin-film solar cells and open new possibilities for further improvement and development. The article aims to deepen the understanding of essential aspects of the synthesis and characteristics of photoelectric materials.
