日本広岛大学高皇敏郎采用放电等离子烧结方法制出以安全元素组成的致密多晶Ba8Ga16Sn30笼形包合物,制成28mm×28mm×5.5mm模块,进行热电性能评估。低温侧为30℃,高温侧为330℃,这时得到的功率密度0.2W/cm2,发电效率为4%。在低温侧与Bi-Te器件组成8对模块,温差为390℃,这时的输出 Gao Huang Min Lang from Japan’s Hiroshima University used a spark plasma sintering method to produce a dense polycrystalline Ba8Ga16Sn30 cage-shaped inclusion complex with a safe element to make a 28mm × 28mm × 5.5mm module for thermoelectric performance evaluation. The low-temperature side was 30 ° C and the high-temperature side was 330 ° C. The power density thus obtained was 0.2 W / cm 2, and the power generation efficiency was 4%. In the low-temperature side and Bi-Te devices composed of 8 pairs of modules, the temperature difference is 390 ℃, then the output
