In the past five years, power conversion efficiency (PCE) of monolithic perovskite/silicon tandem solar cells is improved from 13.7% to 29.15%, demonstrating a massive growth. The electrical and optical properties of interconnecting layers (ICLs) play one of crucial roles in determining the performance of perovskite/crystalline silicon (c-Si) tandems. And the employment of ICLs is directly related with front passivation of bottom c-Si cells. Here, we reviewed the respective development progresses of ICLs for different c-Si bottom cells in monolithic perovskite/c-Si tandem solar cells. Then we present key strategies to realize a good electrical connection and light management. Finally, optimized ICLs were designed to enhance PCE of tandems based on the balance between optical and electrical aspects for different c-Si bottom cells, which will shed light on ICLs of perovskite/silicon tandems.

在过去的五年中，整体式钙钛矿/硅串联太阳能电池的功率转换效率（PCE）从13.7％提高到29.15％，这表明它取得了巨大的增长。互连层（ICL）的电学和光学特性在确定钙钛矿/晶体硅（c-Si）鞣革的性能中起着至关重要的作用。ICL的使用与底部c-Si电池的正面钝化直接相关。在这里，我们回顾了整体钙钛矿/ c-Si串联太阳能电池中不同c-Si底部电池的ICLs的开发进展。然后，我们提出实现良好的电气连接和照明管理的关键策略。最后，根据不同c-Si底部电池的光学和电学方面之间的平衡，设计了优化的ICL以增强单晶的PCE，
