Results of the 1998 JPL Balloon Flight Solar Cell Calibration Program

The 1998 solar cell calibration balloon flight campaign consisted of one flight, which occurred on August 15, 1998. All objectives of the flight program were met. Thirty-one modules were carried to an altitude of = 120,000 ft (36.6 km). Full I-V curves were measured on 4 of these modules, and output at a fixed load was measured on 27 modules. This data was corrected to 28 C and to 1 AU (1.496 x 10(exp 8) km). The calibrated cells have been returned to the participants and can now be used as reference standards in simulator testing of cells and arrays.
