  • Patent number: 11742795
    Abstract: This invention relates to a photovoltaic module intended to convert solar radiation energy in electricity, and, more specifically, to a concentrating photovoltaic module provided with a parabolic dish-shaped mirror and a small-size photovoltaic receiver positioned in the focal plane of this parabolic dish-shaped mirror and the focal spot is overlapped mostly by the photovoltaic receiver. The photovoltaic module is based on usage of combination of a two-phase thermosiphon, which includes a flexible sub-section designed as a bellows, with the parabolic dish-shaped mirror installed on the distal (lower) sub-section of the two-phase thermosiphon by the truss struts. A tracking manipulator is installed below the parabolic dish-shaped mirror and joined with a certain spot of a supporting structure of the parabolic dish-shaped mirror; it provides orientation of the axis of the dish-shaped mirror towards the sun.
