Thermoelectric Module Performance: material_properties_SiGe800
Thermoelectric module (TEC/TEG) performance — Peltier cooler COP, cooling capacity, and voltage at various delta-T and hot-side temperatures, plus thermoelectric material properties (ZT, Seebeck coefficient)
| module category | operating point | ZT | material | notes |
|---|---|---|---|---|
| material_properties_SiGe800 | material | 0.65 | SiGe | SiGe (Si80Ge20 alloy) at 800C (1073K): ZT~0.65, Seebeck ~-180 uV/K (n-type) / +170 uV/K (p-type); thermal conductivity ~4.0 W/(m-K); electrical resistivity ~10e-6 ohm-m. Used in deep-space RTGs (Voyager, Cassini). Best for 600-1000C range. |
