Organic–inorganic hybrid perovskites have been widely used in silicon-based tandem solar cells for their advantages of tunable bandgap, high light absorption coefficient, and high power conversion efficiency (PCE). However, the maximum PCE of perovskite/silicon tandem solar cells (PSTSCs) is still below the theoretical limit. This Review describes the PSTSCs' working principle and then summarizes the research progress in recent years, including a comparison of perovskite layers, interconnection layers, and silicon bottom cells. Then, the n-i-p PSTSCs and p-i-n PSTSCs are presented based on the PSCs' top cells, and the main factors affecting the efficiency of PSTSCs are discussed in detail. Finally, an outlook on the future development of PSTSCs is discussed.
