Innovative thin-film heliotechnologies of decarbonization and ecologization of municipal energy of Ukraine

Abstract

Today, among renewable energy sources, solar power is particularly effective. It is known that solar panels are mainly (more than 95%) based on monocrystalline or polycrystalline (sometimes amorphous) silicon, as a unique semiconductor material. Its irreplaceability is explained by its prevalence in nature, at the same time, the technology of manufacturing silicon solar cells is quite complex and energy-intensive. Therefore, scientists of the world today are working on the search for new materials, in particular, binary, ternary, non-stoichiometric and other compounds They also have satisfactory electrophysical characteristics, however, at present, these tandem and more complex materials have, compared to silicon, significantly lower efficiencies and problems with the timing of their operation. In addition, the absolute majority of them are rare in nature and therefore industrial production is quite problematic.
