The impact of photon recycling (PR) and of luminescent coupling (LC) on the photovoltaic performance of all-perovskite tandem solar cells is analyzed by the means of optical and full opto-electronic device simulation. Optical processes are assessed using a comprehensive Green function formalism that considers wave optical effects also in emission. Starting from a consistent fit of experimental sub-cell and tandem characteristics, the effects of re-absorption are propagated from the optical limit to a situation with consideration of realistic charge transport across the entire tandem device. This also provides insight into the origin of performance losses due to sub-cell and interconnection quality.

通过全光电模拟评估全钙钛矿串联太阳能电池中的光子回收和发光耦合的影响

通过光学和全光电器件模拟的方法，分析了光子回收（PR）和发光耦合（LC）对全钙钛矿串联太阳能电池光伏性能的影响。使用综合格林函数形式来评估光学过程，该形式也考虑了发射中的波动光学效应。从实验子电池和串联特性的一致拟合开始，考虑到整个串联器件中的实际电荷传输，重吸收的影响从光学极限传播到情况。这还可以深入了解由于子单元和互连质量造成的性能损失的根源。
