High vacuum UV test of improved efficiency solar cells
Abstract
Solar cells of a recently developed advanced high-efficiency type were subjected to an ultraviolet environment of 1.5 suns for 1500 hours in a vacuum. Components evaluated included the cell tantalum pentoxide antireflection coating and the 0.35-micron cover filter. The effects of the ultraviolet radiation were measured in terms of cell short-circuit current and spectral response. The data indicated that the high-efficiency solar cell is better than the conventional cell in resistance to ultraviolet radiation. The high-efficiency cell assembly exhibits not only a two-percent gain in glassing when compared to the approximately seven-percent loss for the conventional cell assembly, but also less than half the UV degradation.
