Abstract
A reflective photovoltaic solar concentration system is formed by a primary reflecting mirror (1) changing the direction of the light beams entering the system and redirecting the beams toward a secondary reflecting mirror (2), changing again the direction of the received light beams and redirecting them toward a tertiary optical element (3), which in turn transmits the received light beams to a photovoltaic receiver. The tertiary optical element (3) has a convex-curved input face (4) of circular section, and truncated pyramid section (5) which transmits the received light beams by complete internal reflection to a photovoltaic receiver. The leading end (6) of the truncated pyramid section (5) has, immediately after the input face (4), a circular cross-section (6) which is progressively transformed into a square cross-section until reaching the trailing end (7) of the truncated pyramid section (5).
