IS15387: Measurement Methods for Space Solar Cells
1. Content
   Calibration and measurement methods for single-junction
   solar cells
2. Current status
   Systematic revision has been discussed at the AM0 Workshop
• Focuses only for calibration (exclude characterization)
• Drafting is being asked to ESA/EATEC
• Revison will hopefully be proposed at the next workshop

      NWIP: Solar Cell Characterization Methods
1. Content
    Measurement methods for multi-junction or all kinds of space
   solar cells
2. Current status
   Concept has been discussed at the AM0 Workshop
• Investigateion of current methodology is needed → white paper
• Round-robin measurement of “radiation-damaged” 3J cells is
   planned and being prepared
