Abstract
A solar concentrator () having a longitudinal axis of extension () and a cross-section at right angles to the longitudinal axis substantially equal for a continuum of cross-sections, and comprising a reflective system () and a refractive system (), the reflective system forming an optical inlet () and an optical outlet () and comprising two semi-portions positioned specularly relative to the plane of symmetry, where the cross-section profile of the refractive system is a triangle () having a base () at the optical outlet () and apex () on the axis of symmetry (), where the cross-section profile of each semi-portion of the reflective system comprises a segment () in the shape of a parabola having an axis () forming with the axis of symmetry an acceptance angle (θ0) greater than zero and a focus (F) on the axis of symmetry, and where the focus falls inside the triangle.
