Solar Cell Concentrator System
Abstract
If solar cells are exposed to charged particle radiation, efficiency decreases. Also solar cell efficiency is increased by concentrated solar light. A solar cell concentrator system includes shielding against particle radiation and provides concentrated solar light, with increased efficiency. A solar cell concentrator system was constructed using a GaAs solar cell. Using a heat pipe, heat was transferred to a radiator. Cell operating temperature (77 C) and under concentrated solar light (Concentration Ration = or approx. 130) solar cell efficiency was measured. Observed efficiency was 18.18. + or - 0.18 (%). These results were used to calculate the performance of an array, consisting of small concentrators. The performance of the concentrator array was compared with a conventional array, and demonstrated the higher efficiency advantages.
