How It Compares
Within the halide perovskite photovoltaics class.
Unlike the widely recognized lead-based perovskites such as CsPbBr3 or CsSnI3, which are frequently utilized for their high-performance optoelectronic properties, Ag1Bi1K2 represents a distinct chemical composition that avoids the use of lead. It serves as an alternative structural candidate in the search for stable, non-toxic materials within the diverse family of perovskite-related phases.
