The fabrication of a high-efficiency CIGS thin-film solar cell requires sufficient knowledge of the layer deposition method, thickness, element percentage, and quality of the fabricated samples. In this study, the depth profile of various elements in a laboratory fabricated sample was obtained by non-destructive Rutherford backscattering analysis. For this purpose, a proton beam with an energy of 1350 keV was used. The results of the analysis and simulation of the obtained spectrum measured the order of the layers, the thickness of the layers, and the percentage of elements in each layer with acceptable accuracy. This study emphasizes that the percentage of elements in compounds can be determined at a lower cost than other analyses. Also, due to the depth of proton penetration, this analysis can be easily used to measure elements in multilayer compounds where each layer is composed of different elements. The results obtained showed that thin layers were formed between the main layers of the sample, indicating the diffusion of elements between the layers. Some differences from the stoichiometry considered for the sample were also observed.
