The research goal is to develop models of interaction of solar cells with flows of the gas and the plasma, and electromagnetic radiation in the Earth magnetosphere. The research method is mathematical and physical modeling. It is shown that the deciding influence on a dynamic interaction between a magnetized solid and plasma fluxes in the Earth magnetosphere and other planets of the Solar system are two parameters: a relation a proper magnetic field to a velocity head and a slope of a magnetic dipole axis to a planet rotation axis. A procedure of diagnostics of plasma neutral and charged components using thermal anemometric cylindrical probes under transient conditions of the flow-around (mean and intermediate pressures) is developed. It is found that irradiation of solar cells of spacecraft silicon batteries with a supersonic flow of an atomic oxygen in the polar ionosphere is accompanied by formation of an oxide film on the surface of current-feeding contacts and a decrease in the battery electric capacity. It is shown that under conditions of a quit sun the effects of a long-term action of the ionizing radiation on spacecraft silicon solar batteries (SB) in the magnetosphere, radiation belts in geostationary orbits and in the plasma flux of the Solar wind are practically equal. Solar proton flares increase degradation in the SB capacity. The research results are dedicated to predict degradation in an electric capacity of spacecraft solar batteries at long-term operation in the Earth magnetosphere and the polar ionosphere. Applications: rocket and space technology, plasma and chemical technologies, chemical machine-building and instrument engineering. Product Description popup.authors Бандель К. А. Кочубей Г. С.
