OPTICAL CONCENTRATOR

摘要

System (10) and photovoltaic panel (100) comprising a photovoltaic cell and a photovoltaic solar concentrator (1 ) comprising a reflective system (6) and a refractive system (7), the reflective system comprising two mutually facing half-portions and having concavities directed towards each other, the refractive system comprising a lower portion supporting an upper portion, wherein minimum width of the lower portion is greater than the maximum width of the upper portion. The photovoltaic cell (30) lies on the lower side of the lower portion (15) of the refractive system. The sectional profile of the upper portion has an aspect ratio less than or equal to 0.43.
