Figure 1. (A) Comparison of CV curves of CsPbBr₃/FTO electrode and bare FTO in 0.1 M TBAPF₆ at a scan rate of 50 mV s^-1. (B) dependence of ionic conductivities of the electrolyte with different concentrations of TBAPF₆ in DCM. (C) CV curves of CsPbBr₃ electrode in electrolyte with different concentrations of TBAPF₆ in DCM at a scan rate of 50 mV s^-1. (D) domparison of GCD curves of CsPbBr₃ electrode in 0.1 M and 1 M TBAPF₆ in DCM at the current density of 0.04 A g^-1 and 0.1 A g^-1, respectively.
