SOLAR PHOTOVOLTAIC CONCENTRATOR MODULE Russian patent published in 2018 - IPC H01L31/54 

FIELD: physics.

SUBSTANCE: solar photovoltaic concentrator module contains a primary optical concentrator (3) in the form of Fresnel lenses with a linear size D, the optical axis (4) of which passes through the center (5) of the photocell (1) photoactive region, made in the form of a circle of the diameter d, and a secondary concentrator (6) coaxial with it, made in the form of a quarter wave radial gradana of the diameter d and a height h₁ that is installed at a distance h₂ from the front surface of the Fresnel lens, wherein the values h₁, h₂, and D satisfy the certain relationships.

EFFECT: invention provides the formation of a photovoltaic module with increased reliability, with extended service life, and high energy efficiency due to the equalization of the illumination of the photoactive region and the reduction of the local concentration of solar radiation.
