我们分析了发光耦合对多结电池设计和性能的影响，使用最近开发的形式主义，使用测得的发光耦合参数作为输入的分析模型的全电流-电压（J-V）特性的细胞。完整J-V曲线的这种计算允许在存在发光耦合的情况下确定电池开路电压、短路电流、填充因子和效率。我们表明，发光耦合影响的关键方面的细胞设计，包括最佳的结厚度和带隙，并影响依赖的光照射它的光谱内容的细胞性能。
We analyze the implications of luminescent coupling on multijunction cell design and performance, using a recently developed formalism that uses the measured luminescent coupling parameters as inputs to an analytical model of the full current-voltage (J-V) characteristic of the cell. This calculation of the full J-V curve allows the determination of the cell open-circuit voltage, short-circuit current, fill factor, and efficiency in the presence of luminescent coupling. We show that luminescent coupling affects critical aspects of the cell design that include the optimal junction thicknesses and bandgaps, and affects the dependence of the cell performance on the spectral content of the light illuminating it.
