PHOTOVOLTAIC MODULE WITH COMPOUND PARABOLIC CONCENTRATOR Russian patent published in 2014 - IPC F24J2/10 G02B5/10 

FIELD: physics.

SUBSTANCE: photovoltaic module has a compound parabolic concentrator and a cylindrical photoelectric receiver mounted in the focal region with a cooling device and made in form of a cylinder from switched high-voltage photoelectric converters with length h₀ and internal radius r₀. The concentrator is a body of revolution with a mirror internal surface, consisting of multiple zones (a-b, b-c, c-d), and made composite based on the principle of collecting reflected rays in a focal cylindrical region from separate zones of the concentrator. The shape of the reflecting surface of the concentrator X(Y) is defined by a system of equations matching the condition of uniform illumination of the surface of the photoelectric receiver given in the claim.

EFFECT: enabling operation of the photovoltaic module with high concentrations and uniform illumination of the photoelectric receiver, obtaining technically acceptable voltage at one photoelectric converter, high efficiency of conversion and low cost of the generated energy.
