The two-terminal perovskite/crystalline silicon tandem solar cell combines a wide-bandgap perovskite with excellent optoelectronic properties and a silicon substrate to prepare a high-efficiency solar cell, breaking through the theoretical limit efficiency of single-crystalline silicon solar cells. Although the photoelectric conversion efficiency of more than 30% has been achieved, it is still a certain distance from commercialization. In this paper, the structure and working principle of the twoterminal perovskite/crystalline silicon tandem solar cell are mainly introduced;the key problems and solutions for its performance improvement are analyzed;the research progress of the two-terminal perovskite/crystalline silicon tandem solar cell is given, and its future development is prospected.
