摘要：Among lead-free halide double perovskites, Cs(2)AgBiBr(6 )is a potential alternative to substitute toxic and unstable organic-inorganic lead-based halide perovskites. However, the film forming ability and wide indirect bandgap have impeded its applications. Herein, we investigate to use MoS2 nanoflakes as a hole transport interlayer to improve the crystallinity of Cs2AgBiBr6, tailor energy level alignments and enhance the stability of solar cells. With the addition of the MoS2 nanoflakes, the Cs2AgBiBr6-based solar cell has a power conversion efficiency of 4.17% with an open circuit voltage of 1.10 V and short-circuit current of 6.12 mA cm(-2). This work would provide a new approach for developing all inorganic lead-free Cs2AgBiBr6-based solar cells with high power conversion efficiency and good stability.
