Perovskite/silicon tandem solar cells have been intensively studied in recent years, and their efficiencies have rapidly increased owing to the numerous efforts in this field. A question about which type of silicon solar cell is the most suitable subcell in tandem devices emerges. Herein, three attractive silicon solar cells are summarized, including passivated-emitter rear-cell (PERC), tunnel oxide passivated contact (TOPCon), and heterojunction (HJT) cells. Their structures and features are elucidated for a clear understanding of the mechanism and potential of optimum performance. Moreover, the characteristics and performance of perovskite/silicon tandem cells with PERC, TOPCon, and HJT subcells are contrasted and discussed. The significant contribution of the passivation layer and structure design on both sides to photovoltaic properties of tandem devices is emphasized. Especially, the recombination layer between two subcells is analyzed in depth in terms of material chemistry, light absorption, and charge transport with a review on preparing the optimized structure.

钙钛矿/硅串联太阳能电池：底部器件和复合层的选择
近年来，钙钛矿/硅串联太阳能电池得到了深入研究，由于该领域的大量努力，其效率迅速提高。关于哪种类型的硅太阳能电池是串联装置中最合适的子电池的问题出现了。在此，总结了三种有吸引力的硅太阳能电池，包括钝化发射极背面电池 (PERC)、隧道氧化物钝化接触 (TOPCon) 和异质结 (HJT) 电池。阐明了它们的结构和特征，以便清楚地了解最佳性能的机制和潜力。此外，对比和讨论了钙钛矿/硅串联电池与 PERC、TOPCon 和 HJT 子电池的特性和性能。强调了两侧钝化层和结构设计对串联器件光伏特性的重要贡献。特别是，从材料化学、光吸收和电荷传输方面深入分析了两个子电池之间的复合层，并对优化结构的制备进行了回顾。
