This paper discusses the use of semiconductor solar cells based on thin-film cadmium telluride (CdTe) in modern energy production. The advantages and disadvantages of using CdTe thin-film solar cells are analyzed, and arguments are presented in favor of the implementation of mass production technologies for CdTe solar modules, which can compete with silicon analogs in terms of compromise between efficiency and cost. The physical and chemical properties of the binary Cd-Te system are described, and the relationship between the physical, chemical, electrical, and optical properties of CdTe is analyzed, making it attractive for use in thin-film solar cells. Special attention is given to the investigation of photovoltaic properties, which are important parameters for determining photoconductivity, and the advantages and disadvantages of CdTe film photovoltaic properties are discussed. CdTe thin-film heterostructures (HSs), which are important components of modern solar cells, are considered, and their main advantages and disadvantages are described. It is argued that simple methods of manufacturing and forming HSs, which do not require complex and expensive equipment, are an important advantage of CdTe-based solar cell technology.
