 The rapid development of solar energy converter technologies has driven a growing demand for modern electronic devices with enhanced capabilities and new functionalities. One of the most pressing topics in contemporary scientific research is the development of advanced semiconductor materials for energy conversion and sensing applications. Particular attention is given to the Cu-Sn-S system due to its promising properties for optoelectronic and thermoelectric applications. These materials are considered environmentally friendly and efficient. Compounds like Cu2SnS4 doped with Zn, Mg, Mn, and Se have found extensive use in modern electronic devices due to their chemical stability, availability, low-temperature chemical synthesis methods, and the ability to tailor their properties during synthesis. Despite their widespread application, optimizing the characteristics of known materials remains a challenge, requiring the study and analysis of new compounds with controlled properties in the form of nanoparticles or thin films. Research into the materials of the Cu-Sn-S system enables a thorough investigation of their structural, optical, and electronic properties, aimed at developing functional layers based on heterojunctions. Synthesized nanomaterials have proven suitable for creating various sensitive elements in optoelectronics, flexible electronics, and solar energy applications. The potential of these materials lies in their ability to operate under extreme conditions, such as high temperatures or aggressive environments, as well as their capacity to enable the creation of multifunctional devices. Such research expands our knowledge of the physicochemical properties of materials and helps identify new approaches to their optimization. This paves the way for developing more efficient and reliable devices for modern electronics
