Optical arrangement for concentration of radiation in solar cell concentrator module, has total internal reflection Fresnel lens region that is assigned with focus arranged in refractive Fresnel lens region
The arrangement has a refractive Fresnel lens region arranged in a lens reference area. The refractive Fresnel lens region is assigned with focus (3a) and focused on incident radiation in the focus. A total internal reflection (TIR) Fresnel lens region assigned with the focus is arranged in the refractive Fresnel lens region. The TIR Fresnel lens region is arranged at a distance from the refractive Fresnel lens region. Four strip-shaped Fresnel lenses (1a, 1b, 2a, 2b) are arranged side by side in a longitudinal direction. An independent claim is also included for a solar cell concentrator module comprising an optical arrangement and solar cells.
