CONCENTRATOR LENS SYSTEM

  • Blue rays show the shortest wave-lengths; black median wave-lengths; red, the longest wave-lengths, for different layers of the cell.

 

  • Flux-smoothing optical homogenizer [3] with entrance at the lens focus, tilted towards water.

  • Satellite-developed multi-layer concentrator photovoltaic cell [4], producing 16.14 W/cm2 of electric output under 400 suns.

  • Floating trough swiveling on-axis for tracking in solar elevation.

  • Protruding conduit, enclosing the optical homogenizer, convey surplus heat to water.

Sunlight [1] is focused by planar concentrator lens [2] into tilted optical homogenizer [3], which smoothes out the focused flux  over  the  high-efficiency multi-layer solar cell [4].

                 

Two close-ups are shown of the facets of PYRON-SOLAR’s unique low-cost mini-faceted solar concentrator lens, mass-produced in transparent plastic by high precision molding. It uses conventional refractive facets in its central portion. At the maximum refractive deflection (shown in the left picture), reflective facets take over for the outer, short-focusing lens portion. In the right picture is shown the maximum 45° deflection by the outermost, totally internally reflecting facets.
