摘要

我们提出了一种新的太阳能热光伏(STPV)器件，该器件首次结合了二维光子晶体(2D PhC)吸收-发射体，实现了>10%的光谱转换效率。这些结果是通过钽(Ta)的表面纳米结构来调整吸收-发射光谱特性，并通过创新的真空封闭实验装置最小化寄生热损失来实现的。通过在PV表面加入亚带隙光子反射滤波器并优化吸收-发射比，我们展示了所演示的2D Ta PhCs如何使现实的STPV配置超过0.55 eV电池的Shockley-Queisser最终效率。

2D Photonic-crystals for high spectral conversion efficiency in solar thermophotovoltaics

We present a novel solar thermophotovoltaic (STPV) device, which for the first time, incorporates a two-dimensional photonic-crystal (2D PhC) absorber-emitter to achieve spectral conversion efficiencies >10%. These results were achieved by tailoring the spectral properties of the absorber-emitter through surface nanostructuring of tantalum (Ta) and minimizing parasitic thermal losses through an innovative vacuum-enclosed experimental setup. By incorporating a sub-bandgap photon reflecting filter on the PV surface and optimizing the absorber-emitter ratio, we present how the demonstrated 2D Ta PhCs enable a realistic STPV configuration to exceed the Shockley-Queisser ultimate efficiency of a 0.55 eV cell.
