PHOTOELECTRIC CONCENTRATOR SUBMODULE Russian patent published in 2013 - IPC H01L31/52 

FIELD: physics.

SUBSTANCE: photoelectric concentrator submodule has a front glass sheet (1), on the rear side of which there is a primary optical concentrator in form of a square-shaped lens (2) with side length W and focal distance F. In the central region of the surface of the square-shaped lens (2) there is a coaxially arranged photocell (4) with thickness z₁, which is in form of a square with side length d_b placed on a heat-removing base (3), which is in form of a circle of diameter d₂ or a rectangle with length of the longer side d₂ and thickness z₂. On the photoactive surface of the photocell (4), coaxially with the square-shaped lens (2), there is a secondary optical concentrator in the form of, for example, a truncated glass cone (5) with height h₁, facing the photocell with the smaller base. A rear glass sheet (6), with a light-reflecting mirror coating (7) is mounted parallel to the front glass sheet (1). The distance from the light-reflecting mirror coating (7) to the photocell (4) is equal to L. Values of F, W, d₁, d₂, z₁, z₁ h₁ and L satisfy certain relationships.

EFFECT: invention simplifies the manufacture of a photoelectric submodule while providing high accuracy of mounting the photocell and maintaining good misalignment characteristics, which increases energy efficiency and reliability, reducing material consumption by halving the thickness of the submodule also lowers the cost of manufacturing the photoelectric module.
