PHOTOVOLTAIC MODULE WITH RADIATION CONCENTRATOR Russian patent published in 2024 - IPC H01L31/54 

FIELD: photovoltaic energy.

SUBSTANCE: invention relates to solar and laser energy systems designed to generate electricity on spacecraft. A photoelectric module with a radiation concentrator includes a folding structure with a deployment device, a flat panel (3) of Fresnel lenses and a parallel flat base (1) with photoelectric converters (2) located on the front surface of the base (1) at the foci of the Fresnel lenses. The panel (3) of the Fresnel lenses and the flat base (1) are made of a square shape with the same dimensions of the squares, interconnected by four posts (4-7), attached at their ends to each corner of the panel (3) and to each corner of the base (1) by means of eight spherical hinges (8-15), of which four hinges (12-15) are installed, one on each of the four corners of the base (1), and four other hinges (8-11) are installed, one on each of the four corners of the panel (3) Fresnel lenses. The length of each post (4-7) together with two hinges is set equal to the length of the side of the mentioned squares. At each of the two opposite corners of the base (1) one stepper motor (16, 17) is attached with mutually perpendicular shaft axes parallel to the sides of the base (1).

EFFECT: significant (more than 10 times) reduction in the volume of the module in the packaged (transport) state.
