Concentrator cell efficiency measurement errors caused by unfiltered xenon flash solar simulators
AIP Conference Proceedings(2014)
摘要
In this paper, we examine the effects of increased irradiance into one subcell of triple-absorber concentrator solar cells during efficiency measurements. This situation can easily occur when unfiltered xenon flash solar simulators are used for illumination. We demonstrate how excess irradiance into bottom subcells causes artificially increased fill factors, and that commonly used measurement procedures are unable to account for any excess irradiance. The effect always results in efficiency values that are too high.
