在燃气加热炉中研究了InGaAsSb和GaSb热光伏（TPV）电池的发电性能。给出了TPV电池在燃烧驱动辐射源中的电输出特性。对于InGaAsSb电池，在高于1A/cm 2的短路电流密度下，开路电压高于300 mV。在930-1215°C的辐射温度范围内，InGaAsSb电池的短路电流比GaSb电池的短路电流增加得更快。建立了TPV器件的数学模型，描述了电池带隙和散热器温度对电功率输出和电池效率的影响。此外，燃烧驱动TPV系统的设计方面进行了讨论。
Electric power generation using InGaAsSb and GaSb thermophotovoltaic (TPV) cells was investigated in a gas-fired heating furnace. Electric output characteristics of the TPV cells in the combustion-driven radiant sources are presented. For the InGaAsSb cells, open circuit voltage was higher than 300mV at a short circuit current density above 1A/cm2. The short circuit current of the InGaAsSb cells increased more rapidly than that of the GaSb cells in radiator temperature range 930–1215°C. A mathematical model for the TPV devices was developed to describe the effect of cell bandgap and radiator temperature on electric power output and cell efficiency. Also, the design aspects of the combustion-driven TPV systems are discussed.
