We have theoretically investigated the effect of front electrode on the structure and performances of GaxIn 1−x_{1-{x}} AsySb 1−y_{1-{y}} thermophotovoltaic (TPV) cells. By sampling a comb-like electrode, it is clearly demonstrated here that the optimum grid separation dG{d}_{G} depending on the cell bandgap yields a quadratic function for a given spectrum illumination, while the desired coefficients are strongly temperature-dependent and can be well modeled by an exponential decay expression. Comparing with previous report with constant grid separation, the denser front electrode promises an inferior cell efficiency, but the similar phenomenological method can be still applicable to predict the structure and performance of GaxIn 1−x_{1-{x}} AsySb 1−y_{1-{y}} TPV cells for a given operation environment.

我们从理论上研究了前电极对 GaxIn 1−x_{1-{x}} AsySb 1−y_{1-{y}} 热光伏（TPV）电池结构和性能的影响。通过对梳状电极进行采样，可以清楚地证明，取决于电池带隙的最佳网格间距 dG{d}_{G} 对于给定的光谱照明产生二次函数，而所需的系数强烈依赖于温度并且可以通过指数衰减表达式很好地建模。与之前报道的恒定栅极分离相比，更密集的前电极导致电池效率较差，但类似的唯象方法仍然适用于预测 GaxIn 1−x_{1-{x}} AsySb 1−y_ 的结构和性能适用于给定操作环境的 {1-{y}} TPV 电池。
