SOLAR PHOTOVOLTAIC MODULE WITH CONCENTRATOR Russian patent published in 2012 - IPC H01L31/52 

FIELD: physics.

SUBSTANCE: solar photovoltaic module with a concentrator, having a Fresnel lens with a concentric working profile and a photoelectric detector in the focal plane with a cooling device, characterised by that the Fresnel lens consists of two zones with working profiles, one with concentration of beams from the periphery to the centre, and the other from the centre to the periphery; the receiver is in form of a ring of assembled high-voltage photoelectric detectors with width Δr and inner radius of the circular receiver r₀ defined by the relationship r₀=n₀*Δr, where n₀ is selected from whole numbers n=0…N and the external radius of the lens R-N*Δr, where N is the number of intervals with value Δr.

EFFECT: high efficiency of conversion and low cost of the generated energy.
