本文讨论了在微米间隙热光伏（MTPV）领域取得的进展。初始建模表明，MTPV相对于传统的远场TPV可以实现显著的性能改进。这些性能改进包括功率密度提高10倍，转换效率提高30%至35%，或者将散热器温度要求降低至550°C。最近旨在支持这些预测的实验工作已经成功地证明，早期的电流和电压增强可以在更高的温度下重复进行。更重要的是，这些努力表明，没有未知的能量转移过程发生减少MTPV的潜在效用。与2001年报告的中期预测值结果相比，通过至少具有以下一个特征的试验取得了进展：·在两倍以上的温度（900°C）下进行试验。在50%更小的间隙（0.12 μm）下进行测试·发射极面积从4到100倍的测试
This paper discusses advances made in the field of Micron‐gap ThermoPhotoVoltaics (MTPV). Initial modeling has shown that MTPV may enable significant performance improvements relative to conventional far field TPV. These performance improvements include up to a 10× increase in power density, 30% to 35% fractional increase in conversion efficiency, or alternatively, reduced radiator temperature requirements to as low as 550°C. Recent experimental efforts aimed at supporting these predictions have successfully demonstrated that early current and voltage enhancements could be done repeatedly and at higher temperatures. More importantly, these efforts indicated that no unknown energy transfer process occurs reducing the potential utility of MTPV. Progress has been made by running tests with at least one of the following characteristics relative to the MTPV results reported in 2001:• Tests at over twice the temperature (900°C).• Tests at 50% smaller gaps (0.12 μm)• Tests with emitter areas from 4 to 100 times ...
