Table 1
Selected cell parameter results at the 1st and 20th measurement cycle of HIP-MWT+ with different passivation stacks. The relative changes between 1st and 20th measurement are indicated in brackets.
| Rear passivation | Efficiency (%) | VOC (mV) | jsc (mA/cm2) | FF (%) | jrev (mA/cm2) |
|---|---|---|---|---|---|
| AlOX | 21.2 | 671.4 | 40.2 | 78.65 | 9.7 |
| AlOX after 20 cycles | 21.0 (–0.9%) | 671.9 (+0.1%) | 40.1 (+0.2%) | 77.64 (–1.3%) | 17.4 (+44%) |
| SiON | 20.7 | 665.5 | 39.6 | 78.71 | 1.4 |
| SiON after 20 cycles | 20.7 (0.0%) | 666.2 (–0.1%) | 39.6 (0.0%) | 78.76 (+0.1%) | 2.4 (+42%) |
