Causes of the degradation of the photoelectric characteristics of silicon and thin-film photoconverters during long-term operation are considered. Laboratory tests in high-vacuum conditions under a simulator have shown that a transparent bonding compound based on low molecular weight silicone rubber has greater resistance to the ultraviolet radiation of the sun and to nuclear particle irradiation than epoxy cements, and maintains its elasticity at temperatures down to -180 C. The stability of cells in which polycrystalline films of n-type cadmium sulfide and telluride form the base region of the solar cells was investigated the potential barrier is formed at Cu2Te-CdTe and Cu2S-CdS heterojunctions, where a p-type layer of copper chalcogenide is produced by a chemical substitution reaction (Cu2S) or by discrete deposition in vacuum (Cu2Te). It is concluded that silicon single-crystal solar cells using the system of optical coatings developed and thin-film solar cells based on A2B6 compounds may be used for space and ground applications.
