The paper presents the results of research on the most advanced technology for manufacturing semiconductor photovoltaic energy converters. Methods of manufacturing and research of thin-film heterojunction solar cells based on p-type silicon are analyzed. The materials of the initial components and the structure of the thin-film solar cell were selected. According to the results of the developed technology for obtaining a high-efficiency Converter with a base layer of p-type by sputtering on a vacuum magnetron machine with accelerated heat treatment, ways to improve the performance of solar cells are indicated. The main requirements for the production of the most efficient photovoltaic converters are explained. The electrophysical properties of semiconductors were used as the basis for the material selection criteria
