Study of the Effect of Asymmetrically Parabolic Concentrators (APC) on the Efficiency of a Solar Cell

In this research, Asymmetrically Parabolic Concentrator (APC) was designed. It was made of plate covered with paper that is made of polymer coated zinc available in local market. The APC effects on Silicon solar cell parameters have been studied during the Iraqi spring season (Afternoon March and April) in the city of Mosul. The result showed that in March Solar cell efficiency had increased from (4.9%) to (5.5%) due to the existence of APC, while during April, it did increase from (3.9%) to (7.2%). Four Solar cells of equal dimensions were connected in parallel in order to take advantage of Solar radiation reflected from the center on the surface of cells.
