论文摘要
将低温辐射转换为电力的嗜热伏硫托细胞由于其在许多领域的潜在应用而具有重要意义。在这项工作中，呈现了300 K-480 K的黑体，在黑体的辐射下起作用的BI2TE3/SI热伏燃料细胞。实验结果表明，即使在300 K的辐射温度下，细胞也可以输出电力。BI2TE3/SI杂音的频带结构和BI2TE3薄膜中的缺陷降低了细胞的转化效率。还证明，SI和BI2TE3薄膜的厚度对BI2TE3/SI热伏硫托细胞具有重要影响。尽管细胞的输出功率很小，但这项工作提供了一种使用低温辐射的可能方法。
The thermophotovoltaic cells which convert the low temperature radiation into electricity are of significance due to their potential applications in many fields. In this work, Bi2Te3/Si thermophotovoltaic cells which work under the radiation from the blackbody with the temperature of 300 K-480 K are presented. The experimental results show that the cells can output electricity even under the radiation temperature of 300 K. The band structure of Bi2Te3/Si heterojunctions and the defects in Bi2Te3 thin films lower the conversion efficiency of the cells. It is also demonstrated that the resistivity of Si and the thickness of Bi2Te3 thin films have important effects on Bi2Te3/Si thermophotovoltaic cells. Although the cells' output power is small, this work provides a possible way to utilize the low temperature radiation.
