For these solar cells, conversion efficiency (Z) decreased wit hincreasing temperature, and increased wit hincreasing concentration ratio owing to an increase in open-circuit voltage. The decrease in Z wit hincreasing temperature decreases wit increasing concentration ratio. Moreover, the annual output of a concentrator system wit ha high- efficiency triple-junction cell was estimated utilizing the experimental solar cell’s characteristics obtained in this study and field-test meteorological data collected for 1 year at the Nara Institute of Science and Technology, and com
