Abstract
Spectrolab introduces its latest multi-junction solar cell with efficiency at maximum power at beginning of life of 28.0% (AM0, 28/spl deg/C, 135.3 mW/cm/sup 2/) and 22.6% at 60/spl deg/C after 15 years in GEO orbit. The space-qualification program employed for the Ultra Triple Junction (UTJ) solar cell is the most comprehensive to date, leading the way to improving on-orbit performance predictions. The UTJ cell is currently in qualification and is expected to be in production 2Q 2003.
