Light intensity reliability
| Intensity(W/m²) | 1000 | 900 | 800 | 600 | 400 |
| Uoc | 1.000 | 0.996 | 0.991 | 0.988 | 0.962 |
| Isc | 1.000 | 0.903 | 0.803 | 0.602 | 0.403 |
| * Taking the Voc (Isc) tested at 1000W/m² as the standard, test the decrease of Voc (Isc) with the light intensity. | |||||
Solderability
| Minimum peeling strength | ≥0.5N/mm | ||||
| Results may vary depending on electrode, welding method, and conditions. | |||||
