The environmental toxicity of Pb in organic–inorganic hybrid perovskite solar cells remains an issue, which has triggered intense research on seeking alternative Pb-free perovskites for applications. Halide based group-VA cations Bi3+ and Sb3+ with the same lone-pair ns2 state as Pb2+ are promising candidates.
