Solubility Limit and Optoelectronic Evolution of Heterovalent Bi3+ Doping in MAPbBr3 Perovskite Powders: A Study from Electrochemical Impedance Spectroscopy (EIS)

This paper reports a comprehensive physicochemical and electrical investigation of MAPb1−xBixBr3 perovskite powders (nominal x = 0 to 0.16) synthesized by antisolvent (acetone) precipitation. Structural (XRD/Rietveld) and chemical (EDX/EDS) analyses reveal a dual-regime doping mechanism governed by a thermodynamic solu...
