<p>A photovoltaic solar collector and concentrator apparatus consists of a solid, one-piece, sun light transmitting, non-imaging optical element coupled to a photovoltaic cell. The photovoltaic solar collector and concentrator has an entry surface including focusing elements and an opposed surface including uncoated reflector elements. The focused sun light is directed by the reflector elements via total internal reflection directly towards the photovoltaic cell without any reflection from the entry surface. An additional redirecting element based on total internal reflection and integral with the collector and concentrator optical element is used to couple the sunlight from the reflector elements to a photovoltaic cell positioned in plane parallel to the entry surface.</p> |
