The development of renewable energy technologies for the conversion of solar radiation en-ergy into electrical energy has led to a significant increase in the capacity of solar power generation and requires continues updating of forecasts of technically achievable potential of the Sun's energy when using photovoltaic and new generations equipments. The purpose of this article is to analysis of the exist-ing technologies of photoelectric conversion of solar radiation into electrical energy and the prospects for their use. The paper provides an analysis of three basic technologies for converting solar radiation into electrical energy: thermodynamic, photoelectric, and combined. The analysis of thermodynamic energy conversion technologies of solar radiation shows its effectiveness when direct solar radiation predomi-nates, which in the conditions of Ukraine occurs only in the southern regions. With this in mind, photoe-lectric conversion technologies for four generations: silicon, thin film, dye and perovskite, which are most suitable for the temperate latitudes of our country, are considered in more details. They all have differ-ences in electrical parameters, manufacturing technology, materials and efficiency. For these photovolta-ic technologies, the work provides mathematical dependencies that allow determining electrical charac-teristics, parameters for comparing them with each other, and structural diagrams for a visual representa-tion of the differences between them. The development of photovoltaic technologies according to the data of the world's leading laboratories in the field of photoenergy is considered, which demonstrates the constant development of solar electric technologies in the direction of increasing the efficiency of their operation. The scientific propositions and conclusions formulated in the work are based on the con-ducted theoretical studies, which provide justification for further studies of the theoretically and practi-cally achievable potential of using the theoretically and practically achievable potential of converting solar energy into electrical energy.
