Thermophotovoltaic systems, like all thermal engines, are constrained by the trade-off between efficiency and power density. Standard thermophotovoltaic systems can have efficiency approaching the Carnot limit only when the power density approaches zero. Here, we propose a nonreciprocal thermophotovoltaic system consisting of multiple nonreciprocal photovoltaic layers. With an infinite number of nonreciprocal photovoltaic layers, our engine can operate at the Carnot efficiency while generating nonzero power. Furthermore, we show that with a finite number of layers, nonreciprocal thermophotovoltaic systems can significantly outperform their reciprocal counterparts. Our work points to the opportunities of exploiting nonreciprocity in thermophotovoltaic systems.

单向热光伏系统

与所有热机一样，热光伏系统受到效率和功率密度之间权衡的制约。只有当功率密度接近零时，标准热光伏系统的效率才能接近卡诺极限。在这里，我们提出了一种由多个非互易光伏层组成的非互易热光伏系统。凭借无限数量的不可逆光伏层，我们的发动机可以在产生非零功率的同时以卡诺效率运行。此外，我们表明，在层数有限的情况下，非互易热光伏系统可以显着优于其互易对应系统。我们的工作指出了在热光伏系统中利用非互易性的机会。
