| Abstract: | An experimental study on thermoelectric performance of semiconductor material under low-temperature was performed, which can be used to utilize LNG cold energy. The relationship between performance and cool-side temperature was obtained. The output voltage reaches its maximum when hot-side temperature is invariable and cool-side temperature is under certain circumstance. The theoretical output voltage of thermoelectric material was calculated by numerical method, and was compared with experimental results. |
| Keywords: | low-temperature semiconductor thermoelectric material electric power generation |
