Influence of Cd2+ ions on the carrier properties of NBG perovskites. a and b Normalized transient photocurrent of NBG PSCs with and without Cd2+ ions for electron (a) and hole (b) carriers. c TA kinetics near the exciton bleach (950 nm) of NBG perovskites with and without Cd2+ ions. τ is the average lifetime described in the method. d Steady-state PL of 1000-nm-thick NBG perovskite films with and without Cd2+ ions. All studies in Fig. 3 are based on 1000-nm-thick perovskite film. Source data are provided as a Source Data file
