Ba-induced phase segregation and band gap reduction in mixed-halide inorganic perovskite solar cells
Element doping has been proven a useful strategy to tune the properties of halide perovskites. Here Xiang et al. show that barium unexpectedly does not incorporate in perovskite lattice but induces phase segregation and bandgap reduction and inhibits non-radiative recombination.
