Abstract  —  AM0 solar cell measurements currently require calibrated balloon standards for tuning solar simulators. The uncertainty in the solar cell measurement is largely dependent on the quality of the calibrated balloon standard used to tune the simulator. Current practices reduce this uncertainty to ~1% while requiring expensive and infrequent methods for obtaining new calibration standards. This paper outlines an effort to reduce the uncertainty of the calibration standard, while providing a solution for low cost and frequent laboratory grade characterization in the near space environment.
