<p>A concentrated photovoltaic system includes a photovoltaic cell (5); a primary light concentrating optic (1,7); and a secondary light mixing concentrator (4). The primary light concentrating optic (1,7) is arranged to collect solar radiation and concentrate the collected solar radiation towards the secondary light mixing concentrator (4). The secondary light mixing concentrator (4) is arranged to concentrate the concentrated solar radiation from the primary light concentrating optic (1,7) towards the photovoltaic cell (5). The secondary light mixing concentrator (4) includes a dielectric member having first and second primary surfaces, with the second primary surface being in optical contact with the photovoltaic cell (5) and the first primary surface facing the primary light concentrating optic (1,7). The first primary surface has a non-planar surface structure (6) configured to redirect light which is reflected at transitional surfaces between the secondary light mixing concentrator (4) and the photovoltaic cell (5) back towards the photovoltaic cell (5).</p> |
