Abstract
We present an experimental characterization study of high-efficiency ultra-small multi-junction concentrator solar cells. Particular emphasis is placed on the sensitivity of photovoltaic performance to the intensity and distribution of the concentrated sunlight delivered to the cell. This type of information is important in the design and optimization of the most recent generations of high-concentration photovoltaic systems. Miniaturizing the solar cell can give rise to an increase in the concentration value at which cell efficiency peaks, facilitates passive heat rejection and permits the use of all-glass optics. However, few measurements have been published for ultra-small cells. We report and analyze extensive measurements, up to approximately 5000 suns, on the 1.0 mm2 active region within the busbars of such commercial concentrator solar cells.
