REFLECTIVE PHOTOVOLTAIC SOLAR CONCENTRATION SYSTEM

摘要

The invention relates to a reflective photovoltaic solar concentration system formed by a primary reflector mirror (1) that changes the direction of the light beams entering the system and redirects them towards a secondary reflector mirror (2) that then changes the direction of the received light beams and redirects them towards a tertiary optical element (3) that, in turn, transmits the received light beams to a photovoltaic receiver. The tertiary optical element (3) has a convex inlet face (4) with a circular cross-section, and a truncated pyramid-shaped section (5) that transmits the received light beams to a photovoltaic receiver by total internal reflection. The initial end (6) of the truncated pyramid-shaped section (5) has, immediately following the inlet face (4), a circular cross-section (6) that progressively transforms into a square cross-section up to the final end (7) of the truncated pyramid-shaped section (5).
