Development of lead-free inorganic perovskite material, such as Cs 2 AgBiBr 6 , is of great importance to solve the toxicity and stability issues of traditional lead halide perovskite solar cells. However, due to a wide bandgap of Cs 2 AgBiBr 6 film, its light absorption ability is largely limited a...
