摘要

热光电（TPV）电池通过转换热源发出的红外辐射来发电。气桥冠捷光伏电池通过回收带隙以下（带外）光子携带的大量电能，提高了功率转换效率。在这里，我们展示了单结 InGaAs（P）气桥热塑性硫化弹性体，在 1435°C 黑体照明下，其效率高达 44%。对于带隙范围在 0.74 至 1.1 eV 之间的三元和四元热塑性硫化弹性体，气桥设计可实现接近统一的带外光子反射率（97%-99%）。这些结果表明，气桥电池适用于一系列半导体系统，适合利用消费和工业应用中的热源发电，包括热电池。

High-efficiency air-bridge thermophotovoltaic cells

Thermophotovoltaic (TPV) cells generate electricity by converting infrared radiation emitted by a hot thermal source. Air-bridge TPVs have demonstrated enhanced power conversion efficiencies by recuperating a large amount of power carried by below-band-gap (out-of-band) photons. Here, we demonstrate single-junction InGaAs(P) air-bridge TPVs that exhibit up to 44% efficiency under 1,435°C blackbody illumination. The air-bridge design leads to near-unity reflectance (97%–99%) of out-of-band photons for ternary and quaternary TPVs whose band gaps range from 0.74 to 1.1 eV. These results suggest the applicability of the air-bridge cells to a range of semiconductor systems suitable for electricity generation from thermal sources found in both consumer and industrial applications, including thermal batteries.
