Buried Interface Regulation with TbCl₃ for Highly-Efficient All-Inorganic Perovskite/Silicon Tandem Solar Cells.

ABSTRACT: All-inorganic perovskite materials exhibit exceptional thermal stability and promising candidates for tandem devices, while their application is still in the initial stage. Here, a metal halide doping strategy was implemented to enhance device performance and stability for inverted CsPbI₃ perovskite solar cells (PSCs), which are ideal for integration into perovskite/silicon tandem solar cells. The lanthanide compound terbium chloride (TbCl₃) was employed to improve buried interface between [4-(3,6-Dimethyl-9H-carbazol-9-yl) butyl] phosphonic acid (Me-4PACz) and perovskite layer, thereby enhancing the crystallinity of CsPbI₃ films and passivating non-radiative recombination defects. Thus, the inverted CsPbI₃ PSCs achieved an efficiency of 18.68% a
