论文摘要
$ JV $的分析表达式得出了三种类型的多开关配置的特征。从这些情况下，对于多末端设备和串联连接的串联堆栈，可以发现短路电流的表达式，开路电压和电压。对于匹配电压匹配的设备，建立了底部细胞数量与顶部细胞数量的最佳比例的表达式。整篇文章中都纳入了发光耦合。应该强调的是，通过单个分析表达式，描述了连接串联堆栈的最大功率点，对于所有有趣的带隙组合，都具有良好的精度。尽管建模是假设以辐射极限运行的设备进行的，但建议结果可能会形成一个框架，可以进一步开发和适应以描述非理想设备。
Analytic expressions for the $JV$-characteristics of three types of multi-junction configurations are derived. From these, expressions for the short circuit current, open circuit voltage and voltage at the maximum power point are found for multi-terminal devices and for series-connected tandem stacks. For voltage-matched devices, expressions for the optimal ratio of the number of bottom cells to the number of top cells are established. Luminescent coupling is incorporated throughout the article. It should be highlighted that the maximum power point of a series connected tandem stack is described, with good accuracy for all interesting band gap combinations, by a single analytic expression. Although the modeling is carried out assuming devices that operate at the radiative limit, it is suggested that the results may form a framework that can be further developed and adapted to describe non-ideal devices as well.
