Abstract: In this work, nickel silicide was applied to tandem solar cells as an interlayer. By the process of thermal evaporation, a layer of NiO x , hole transport layer (HTL) was deposited on n + poly-Si layer directly. Nickel silicide was simultaneously formed by nickel diffusion from NiO x to n + poly-Si layer during the deposition and annealing process. The I–V characteristics of NiO x /n + poly-Si contact with nickel silicide showed ohmic contact and low contact resistivity. This structure is expected to be more advantageous for electrical connection between perovskite top cell and TOPCon bottom cell compared to the NiO x /TCO/n + poly-Si structure showing Schottky contact. Furthermore, nickel silicide and Ni-deficient NiO x thin film formed by diffusion of nickel can improve the fill factor of the two sub cells. These results imply the potential of a NiO x /nickel silicide/n + poly-Si structure as a perovskite/silicon tandem solar cell interlayer.
