Electrical properties of GaInP/GaAs/InGaAs TJ solar cells with various electrode structures obtained from J–V curve.
| InGaAs type | Voc(V) | Jsc (mA/cm2) | FF (%) | η (%) |
|---|---|---|---|---|
| Single-junction InGaAs solar cell | 0.35 | 57.65 | 71.24 | 14.37 |
| Dual-junction solar cell | 2.27 | 11.44 | 79.25 | 20.58 |
| Triple-junction solar cell | 2.52 | 13.66 | 78.30 | 26.95 |
Voc: open-circuit voltage; Jsc: short-circuit current density; FF: fill factor; η: efficiency.
