AM0 solar cell calibration under near space conditions

The realization of 3, 4 and 6-junction solar cells for space applications requires a better understanding of the atmospheric effects for all earth-based, high-altitude, AM0 solar cell calibration methods. The residual atmosphere in these methods can have a profound influence on solar cell calibration. Using atmospheric modeling, and calibration methods used past, present, and future, the error introduced by the residual atmosphere is calculated for advanced multi-junction solar cells.
