The efficiency of perovskite-based tandem solar cells and the respective efficiency gain over the single-junction operation of the bottom cell strongly depend on the performance of the component cells. Thus, a fair comparison of reported top cells is difficult. We therefore compute the tandem cell efficiency for the combination of several semitransparent perovskite top solar cells and crystalline silicon or chalcopyrite bottom cells from the literature. We focus on four-terminal configurations but also estimate and discuss the differences between four- and two-terminal configurations. For each top cell, we thereby determine the tandem cell performance as a function of the bottom cell efficiency, which results in a linear relationship. From these data, we extract two parameters to quantify the suitability of the top cell: (i) the slope of the tandem vs. bottom cell efficiency, which is the effective transparency of the top cell, and (ii) the tandem cell efficiency for a targeted bottom cell. These two figures of merit were calculated for a representative set of bottom cells and may serve for comparison of semitransparent perovskite top cells in the future.

半透明钙钛矿太阳能电池在四端子串联电池中的性能评估

基于钙钛矿的串联太阳能电池的效率以及在底部电池的单结操作上的各个效率增益在很大程度上取决于组成电池的性能。因此，很难对所报告的顶部细胞进行公平的比较。因此，我们从文献中计算了几种半透明钙钛矿顶部太阳能电池与晶体硅或黄铜矿底部电池的组合的串联电池效率。我们关注于四端子配置，但也估计并讨论了四端子配置和两端子配置之间的差异。因此，对于每个顶部电池，我们将串联电池性能确定为底部电池效率的函数，从而得出线性关系。从这些数据中，我们提取两个参数以量化顶部单元格的适用性：（i）串联电池效率与底部电池效率的斜率，这是顶部电池的有效透明度，以及（ii）目标底部电池的串联电池效率。这两个品质因数是针对一组代表性的底部单元格计算得出的，将来可用于比较半透明钙钛矿顶部单元格。
