报道了InAs热光伏（TPV）电池，其峰值波长的外量子效率在低温下达到71%，在室温下达到55%，这是迄今为止InAs的最高值。在100 K电池温度下，TPV的功率转换效率为10%。在不同的电池温度（100-340 K）下测量了响应于500-800 °C范围内的热源的暗和亮电流-电压特性。由此产生的依赖性的输出电压和电流，以及光谱响应的InAs热塑性硫化弹性体已被广泛的特点为废热回收应用。这些电池的性能强烈地由暗电流决定，暗电流随着源于带隙变窄的电池温度的增加而快速增加，这导致开路电压和输出功率的降低。
InAs thermophotovoltaic (TPV) cells with external quantum efficiency at the peak wavelengths reaching 71% at low temperature and 55% at room temperature are reported, which are the highest values to date for InAs. The TPV exhibited 10% power conversion efficiency at 100 K cell temperature. The dark and light current-voltage characteristics were measured at different cell temperatures (100–340 K) in response to heat sources in the range 500–800 °C. The resulting dependences of the output voltage and current as well as the spectral response of the InAs TPV have been extensively characterized for waste heat recovery applications. The performance of these cells is strongly determined by the dark current which increases rapidly with increasing cell temperature originating from bandgap narrowing, which resulted in a reduction of open circuit voltage and output power.
