SPACECRAFT SOLAR BATTERY Russian patent published in 2017 - IPC B64G1/44 H01L31/04 

FIELD: physics.

SUBSTANCE: spacecraft solar battery (SB) has a flexible film-honeycomb structure, the honeycombs of which are made in the form of tetrahedral or hexagonal pyramids. Pyramids are connected to each other along the edges of their imaginary bases. Photoelectric converters are placed on the side faces of pyramids, taking solar radiation from the side of the indicated bases. In the deployed position, the SB can have a spherical configuration, in which the vertices of all the pyramids converge at the center of the sphere. A protective film with special properties can be placed on the working surface of the SB. The honeycomb design of the SB in the deployed position is eliminated by heating it to the evaporation temperature of the film or higher.

EFFECT: increasing the efficiency of solar batteries by increasing the absorption coefficient by increasing the number of light reflections from the photoreceiving layer inside the pyramids, reducing the dependence of the absorption coefficient on the incidence angle of solar radiation, and simplifying the technology of manufacturing and operating the solar battery.
